ABB Inora 4 Gang 2 Way 10AX Switch Starry Black BL108-885

The 10AX marking indicates that the switch is designed for lighting circuits with a rated current of up to 10 A and has been tested for loads that can produce higher switching stresses than basic resistive loads. This makes it suitable for many common lighting applications, including compatible LED drivers and fluorescent lighting equipment. The connected load, inrush current and circuit protection must still remain within ABB's specifications and the electrical designer's requirements.

Four-gang describes the number of independent switch mechanisms on the plate, so this model can control four separate circuits or lighting groups. Two-way describes the switching function: each circuit can be controlled from two locations when connected to another compatible two-way switch. The ABB BL108-885 combines both features in one unit.

This switch is suitable for indoor lighting control in villas, apartments, offices, shops, hotels and other building projects. Typical applications include controlling multiple lighting zones in living rooms, corridors, meeting rooms, bedrooms, reception areas and open-plan spaces. It should only be installed in an environment and enclosure appropriate to its stated product rating.

Yes. Each gang has a two-way switching function and can be wired with a compatible two-way switch at another location. This arrangement is useful for staircases, corridors, rooms with two entrances and bedrooms where lighting control is required at both the doorway and bedside. Correct common and traveller conductor connections are essential.

A two-way switch can generally be configured for one-way operation by using the common terminal and one switched terminal for each required circuit. The unused two-way terminal remains unconnected. Wiring must follow the terminal markings and ABB installation instructions, and the work should be completed by a qualified electrician.

It may be used with compatible LED lighting circuits, subject to the total operating current and the driver's inrush current. LED drivers can draw a brief startup current that is much higher than their normal running current, so suitability should not be determined by lamp wattage alone. For projects with numerous fittings on one gang, confirm the driver data and switching capacity with the electrical consultant or ABB.

Isolate and verify the electrical supply before installation. Confirm that the wall box, mounting arrangement and wiring space are compatible, then identify the supply common, switched outputs and traveller conductors for each gang. Connect the conductors according to the terminal markings and approved wiring diagram, secure the mechanism without trapping cables, fit the faceplate and test every circuit. Installation should be performed by a licensed or qualified electrician.

A one-way arrangement typically requires a live feed and switched-live connection for each controlled circuit. A two-location arrangement also requires the appropriate traveller conductors between the paired switches. Because four gangs can create a high conductor count, the electrician should provide a suitably sized back box, adequate cable-management space and correctly identified conductors based on the approved electrical design.

The ABB Inora BL108-885 is relevant to UAE residential and commercial fit-outs that require multi-circuit lighting control and a modern black finish. Product selection and installation must comply with the approved project specification, applicable UAE electrical requirements and the regulations of the relevant local authority or utility, such as DEWA or the competent authority in the project emirate.

Yes. The Starry Black finish works well with dark accessories, feature walls, stone surfaces, timber finishes and contemporary metal details. For a consistent fit-out, verify that matching sockets, data outlets and other wiring accessories are available within the required ABB Inora range and finish before finalising the project schedule.

The product is primarily specified as a 10AX lighting switch. It should not automatically be used for ceiling fans, motors, pumps, water heaters or heavy appliances because these loads may have different current and inrush characteristics. Use a purpose-rated control, isolator, contactor or fan controller where required by the equipment manufacturer and electrical design.

Do not assume that the switch is weatherproof or suitable for direct exposure to rain, dust, condensation or water. For bathrooms, balconies, gardens, plant rooms and other wet or outdoor areas, the installation must meet the required ingress-protection rating, zoning rules and local electrical regulations. A suitably rated weatherproof enclosure or dedicated outdoor switch may be necessary.

Confirm the model number BL108-885, four-gang configuration, two-way function, 10AX rating and Starry Black finish against the approved material submittal. Contractors should also verify wall-box compatibility, mounting dimensions, available wiring depth, circuit load, matching accessories and the quantity required for each lighting-control location.

Isolate the circuit before inspection or maintenance. Clean the visible surface using a soft, dry or slightly damp cloth, and avoid abrasive pads, solvents and strong chemical cleaners that may affect the finish. If a switch becomes loose, discoloured, unusually warm, noisy or inconsistent in operation, stop using the affected circuit and have it inspected by a qualified electrician.
