ABB Millenium 13A Fused Connection Unit with Flex and LED Black Glass AM50853-BG

A 13A fused connection unit, commonly called an FCU or fused spur, is used to connect a fixed or semi-fixed appliance to the building's electrical circuit through a replaceable fuse. The flex outlet allows the appliance cable to leave the faceplate neatly, making this unit suitable for equipment that requires a dedicated local isolation and connection point.

It may be used for compatible fixed appliances such as water heaters, extractor fans, kitchen equipment, ventilation equipment and selected pumps or building services accessories, provided the appliance voltage, current, starting load and manufacturer instructions are compatible. The connected load must not exceed the FCU's 13A rating, and the fuse should be selected to protect the appliance flex rather than automatically using the maximum fuse size.

The documented specifications include a 13A rated current, 230V AC rated voltage, 1-gang configuration, fused connection unit connector type, switched local control, LED status indication, flex outlet and flush-mounted installation. Its stated dimensions are approximately 42 x 86 x 86 mm, and the faceplate is finished in black glass.

The integrated LED provides a visible indication of the switch or connected-circuit status, helping users identify whether the supply has been locally switched on. The precise indication can depend on the product's internal wiring arrangement, so the terminal diagram and ABB installation instructions should be checked during installation.

Yes. The FCU incorporates a fuse that provides localized overcurrent protection for the connected appliance and its flexible cable. Correct protection depends on fitting the fuse type and rating specified by the appliance manufacturer and electrical design. The fuse does not replace the distribution board's required circuit breaker, RCD or other protective devices.

The unit is designed for flush installation with the permanent wiring and mounting box concealed behind the finished wall. The supply, load, neutral and earth conductors must be terminated at the correctly marked terminals, while the appliance flex should pass through the designated outlet and be secured as instructed. Installation, isolation, testing and energisation should be completed by a qualified electrician using ABB's wiring diagram.

The electrician should confirm the 230V AC supply, connected-load current, cable size, fuse rating, earthing arrangement, back-box compatibility, circuit protection and required isolation method. The installation should follow the current regulations of the relevant UAE authority, such as DEWA or the applicable local utility, together with project specifications, manufacturer instructions and recognized low-voltage wiring practices.

It should only be used within its documented 13A, 230V AC rating and where its switching and isolation arrangement satisfies the appliance manufacturer's requirements. High-load equipment, motors with significant starting current, air-conditioning equipment or loads requiring double-pole isolation may need a dedicated isolator, contactor or higher-rated protective arrangement selected by the electrical designer.

Confirm the ABB model number AM50853-BG, SKU 82100-NOS, black glass finish, 1-gang format, 13A rating, 230V AC rating, flex outlet, LED indicator and flush-mounted configuration. Also check compatibility with the selected ABB Millenium frame or surrounding accessories, the available back box and the project's approved electrical accessory schedule.

Isolate the circuit before inspection or maintenance. Clean the glass surface with a soft, dry or slightly damp non-abrasive cloth, and do not use aggressive solvents, abrasive pads or excessive water. A qualified electrician should investigate heat discoloration, looseness, cracking, unusual odours, repeated fuse operation or an LED that no longer indicates the expected status.

Contractors should coordinate the mounting height, back-box position, cable route and appliance flex exit before plastering, tiling, glass installation or joinery completion. The box should be level and set at the correct finished-wall depth so the black glass faceplate sits evenly without pressure or gaps. The surface should be protected from cement, paint, grout and impact until final testing and handover.

The finished wall should provide a compatible 1-gang flush box with sufficient internal depth for the mechanism, cable bend radius and safe conductor termination. The stated product dimensions are approximately 42 x 86 x 86 mm, but the installer should verify the ABB mounting drawing, fixing centres and required box depth before cutting walls, closing gypsum partitions or completing tile and joinery work.

It may be considered for an appropriate indoor location, but it should not be assumed to be water-resistant because no IP rating is stated in the supplied specifications. In kitchens, bathrooms, utility rooms or other damp areas, the electrician must assess the installation zone, moisture exposure, required IP protection, RCD requirements and local regulations. Use a suitably rated accessory or enclosure where water or condensation may reach the unit.

The ABB Millenium AM50853-BG is a 1-gang, flush-mounted fused connection unit designed to provide local control and fused protection for a fixed electrical appliance or load. It has a 13A rated current, 230V AC rating, flex outlet, switched operation, LED status indication and a premium black glass finish.
