CX Series Bottom Mount Fridges
MR-CX450ER-MB-A
The Mitsubishi Electric 450L 3-Door Bottom Mount fridge is designed for everyday kitchen use, offering a practical balance of capacity, organisation and cooling performance. Finished in Matte Black, it features a compact footprint suited to smaller kitchens while providing flexible storage across three clearly defined zones. With an automatic ice maker, a dedicated vegetable drawer and a bottom freezer layout, this fridge supports easy organisation and reliable food storage for daily living.
Organisation designed for everyday living
The 450L 3-Door Bottom-Mount fridge in Matte Black is designed for contemporary Australian homes where space and visual balance matter. Its clean, flat-door finish and muted matte surface minimise reflections and fingerprints, making it a practical choice for everyday kitchens. The compact footprint lets the fridge fit comfortably into smaller cavities while still delivering a generous 450-litre capacity. With a bottom-mount layout and clearly defined doors, this black fridge provides easy access to frequently used items while creating a strong, understated focal point in the kitchen.
Consistent cooling is key to keeping food fresh for longer, and this Mitsubishi Electric fridge is designed with that in mind. The Multi Airflow System circulates cool air evenly throughout the compartment, helping maintain stable temperatures across all shelves and door pockets. The Supercool Chilling Case stores meat and fish at around –3°C to 0°C without freezing, making meal preparation more convenient. In the dedicated vegetable drawer, VitaLED lighting supports produce freshness by slowing wilting, helping fruit and vegetables stay crisp for longer in daily use.
Every storage zone is designed for practical organisation and everyday use. Adjustable tempered glass shelving, including the Two-Way Flexi Glass Shelf, allows the internal space to be adapted for taller items or bulk groceries as needs change. The bottom freezer drawer provides clear visibility and generous space for frozen food, with a top tray for organising smaller items and a second section that collects ice from the Automatic Ice Maker. Wide door pockets and clearly defined compartments help keep food organised, accessible and easy to manage throughout the week.
Great for storing dairy products, fresh fish or meat and chilling drinks.
The Supercool Chilling function is ideal for storing meat, fish or other perishable food at about -3˚C to 0˚C without freezing it. This provides the convenience of food ready to cook without the need to defrost it. Please note this mode must be manually set in order to function.
There is no need for a separate plumbing connection. The removable water tank can be filled with water and the Ice Maker is ready to go!
The Tempered Glass Shelves are easy to clean and built to withstand up to 100 kilograms of weight.
Make the Tempered Glass shelf deeper or push it in for more space. It is ideal for storing taller items such as a salad or dessert bowl.
Designed to maximise the freshness of produce. The drawer features a higher humidity than the main refrigerator compartment and is ideal for storing and keeping fruit and vegetables crisper and fresher for longer.
It is roomy enough to fit bulky items such as ice cream tubs, loaves of bread and frozen vegetables. The top tray is ideal for storage and organisation of flat pack items such as meat packs. A second section of the tray at the top of the drawer collects ice made by the Automatic Ice Maker.
With different temperature points in the fridge, this technology efficiently cools all food, even in hard-to-cool places such as filled door pockets.

Three door fridges, such as the Mitsubishi Electric 450L Bottom Mount model, are designed to balance space efficiency with everyday practicality. The separate refrigerator, vegetable drawer and freezer compartments make it easier to organise food and access items without opening the entire fridge, helping reduce cold air loss and support consistent temperatures.
A key advantage is the ability to enjoy advanced features often found in larger French door fridges, including an automatic ice maker and Supercool Chilling Case, within a more compact design. This makes three door models well suited to apartments and kitchens with limited cavity space, while still delivering generous capacity and modern functionality for everyday use.
The automatic ice maker in the Mitsubishi Electric 450L fridge is designed for everyday convenience without the need for a plumbed water connection. A removable water tank is filled manually, allowing you to use tap or filtered water if preferred. Once filled, the fridge automatically produces ice and stores it in a dedicated section within the freezer drawer.
This non-plumbed design is especially useful in kitchens where installing a water line is not practical, such as apartments, rental properties, or homes without an existing water connection near the fridge cavity. It also allows greater flexibility in fridge positioning and avoids ongoing costs associated with fixed water filters.
The Mitsubishi Electric 450L 3 Door Bottom Mount fridge is available from a wide range of retailers across Australia. You can use the Find a Stockist tool to locate stores near you and see where this model is available for purchase.
Visiting a retailer lets you view the fridge in person, compare finishes, and speak with sales staff about its suitability for your kitchen space and needs.
You can use the Mitsubishi Electric Fridge Finder App to help identify fridge models that suit your lifestyle, kitchen space and design preferences. The app guides you through a few simple questions to narrow down suitable options based on capacity, layout and features.
The VR Photo feature allows you to input your fridge cavity dimensions and see which models will fit within the available space. By taking a photo of your kitchen and outlining the cavity area, the app overlays realistic fridge images so you can compare different models, colours and finishes before making a decision.
Available for iOS devices.
All Mitsubishi Electric fridges come with 5 years warranty on parts and labour and 10 years warranty on the Inverter compressor.
Yes. The Mitsubishi Electric 450L 3 Door Bottom Mount fridge is designed with a compact footprint that suits smaller kitchens and apartment living, while still offering generous internal capacity. Its three-door layout helps maximise usable space without requiring the wider cavity often needed for larger French door models. If you’re comparing options for limited spaces, our guide to the top refrigerators for small spaces and apartments provides helpful insights.
Does the Mitsubishi Electric 450L fridge require plumbing for the ice maker?
No. The automatic ice maker operates without a plumbed water connection. It uses a removable water tank that is filled manually, allowing greater flexibility in where the fridge can be installed. This design is particularly useful in apartments, rental properties, or kitchens where installing a water line is not practical, while still providing the convenience of automatic ice production.
The CX Series features steel door finishes, available in the following colours:
The CGX Glass Series offers a glass door finish, available in:
The differences between the CX and CGX Series relate primarily to the front doors and drawer finishes. Internal layout, capacity and core features are comparable across both series, allowing you to choose the finish that best suits your kitchen design.
To allow for proper airflow and efficient operation, the following minimum clearance dimensions are recommended:
Ensuring these clearances are met helps support performance and longevity. Always confirm your fridge cavity dimensions before installation and refer to the installation instructions for full guidance.
The Matte Black finish is designed for everyday use and helps minimise the appearance of fingerprints and reflections compared to high-gloss surfaces. Regular cleaning with a soft cloth and mild detergent is usually sufficient to keep the finish looking its best. Avoid abrasive cleaners or harsh chemicals to maintain the appearance of the front doors and drawers over time.
Moving a fridge requires care to protect both the appliance and your home. Key considerations include transporting the fridge upright, allowing time for the refrigerant to settle before switching it on, and checking access points such as doorways and hallways in advance. Our fridge moving FAQs cover the most common questions to help make installation and relocation smoother.
Mitsubishi Electric has been recognised for quality and reliability, earning the CHOICE Best Brand Fridges Award multiple times.
