ABB Metal Clad 2 Gang 2 Way 10AX Switch BM106

The term 2 gang means that the switch has two independently operated rockers for controlling two circuits. The term 2 way means that each circuit can be controlled from two different switch locations when the BM106 is connected to another compatible two-way switch. This configuration is commonly used in corridors, staircases, warehouses and rooms with more than one entrance.

The 10AX designation indicates a nominal 10-amp switch rating with additional suitability for certain lighting loads that can produce higher switching currents, such as fluorescent or inductive lighting circuits. The actual connected load must still be checked against the lamp type, driver characteristics, inrush current, circuit protection and ABB technical documentation.

The ABB BM106 is relevant to UAE villas, apartment service areas, workshops, warehouses, plant rooms, garages, retail back-of-house spaces and light-industrial projects where a durable metal-clad accessory is preferred. Its construction is particularly useful in areas exposed to frequent handling or minor mechanical impact, subject to the environmental rating required by the project.

Yes. A two-way switch mechanism can generally be wired for one-way operation by using the common terminal and one of the switched terminals. The unused terminal should remain correctly isolated within the enclosure. Wiring must follow the terminal markings, ABB instructions and the approved project circuit diagram.

Installation should begin by isolating and verifying the electrical supply as dead. The installer should mount the compatible enclosure securely, route and terminate the conductors according to the marked common and two-way terminals, connect the protective earth to the designated earthing point, refit the front plate and test both circuits. Installation and testing should be completed by a qualified electrician.

Yes. Because the accessory has exposed conductive metal parts, effective protective earthing is essential. The circuit protective conductor should be connected to the designated earth terminal, and earth continuity should be verified after installation. Any metallic back box or connected metal conduit must also be bonded as required by the applicable wiring regulations and project specification.

It should not be treated as weatherproof unless the complete installed assembly has a confirmed IP rating suitable for the location. For outdoor, wash-down, dusty or humid UAE environments, use an appropriately rated enclosure and accessories selected for expected rain, dust, condensation, heat and UV exposure. Check ABB documentation and the project requirements before outdoor use.

It may be used with compatible LED lighting, but selection should not be based only on the total wattage. LED drivers can create significant inrush current that may exceed the switch's practical capacity even when the steady-state current is low. Confirm the driver load, quantity of fittings, inrush data and switching recommendations; use a contactor or suitable control device where necessary.

Cable size and protective device selection depend on the design current, installation method, ambient temperature, grouping, voltage drop, fault protection and local project requirements. The switch rating must not be used as the sole basis for cable selection. A qualified electrical designer or electrician should coordinate the BM106 with the circuit breaker, conductor size and connected lighting load.

Installation should comply with the applicable UAE authority regulations, approved project specifications and recognized wiring practices, commonly including BS 7671 where adopted. Requirements can vary between authorities and developments, including DEWA, ADDC or TAQA distribution requirements and other local entities. Product conformity, circuit protection, earthing, conductor identification and final testing should be verified before energization.

A metal-clad switch provides a rigid, durable finish suited to workshops, stores, garages, service corridors and similar working environments where plastic accessories may be more vulnerable to accidental impact. It also offers a practical industrial appearance. Metal cladding does not automatically provide water or dust protection, so the required IP rating must be assessed separately.

The electrician should inspect terminal tightness and conductor identification, verify protective-conductor continuity, confirm insulation resistance and polarity, and test the operation of both gangs from every control location. Relevant circuit protection and earth-fault performance should also be checked in accordance with the approved testing procedure before the installation is placed into service.

Keep the switch clean and dry, and inspect it periodically for loose mounting, damaged metalwork, overheating, discoloration, abnormal noise or unreliable switching. Do not spray water or cleaning liquid directly onto the accessory. Isolate the circuit before inspection or replacement, and have any damaged or overheated unit assessed by a qualified electrician.
