ABB Inora 1 Gang 1 Way 20AX Double Pole Switch with Illumination, Small Rocker Starry Black BL111S-885

One gang means the unit has one independently operated rocker. One way means it controls a circuit from a single switching location. DP stands for double pole, indicating that the switch can disconnect two conductors simultaneously when correctly wired. In UAE installations, this is commonly used where isolation of both live and neutral is required by the circuit design.

The 20AX designation identifies the switch's rated switching capacity and suitability for certain loads with demanding inrush characteristics, including compatible lighting loads. It should not be selected solely from the normal running current: the electrician must also consider startup current, power factor, load type, cable size, protective device rating and the manufacturer's technical limits.

The integrated LED provides a visible status or location indication, depending on the product's terminal arrangement and approved wiring method. This can be useful in utility rooms, plant areas, kitchens and other locations where users need to identify or monitor the switch easily. The installer should follow the ABB wiring diagram because LED behaviour can depend on how the indicator terminals are connected.

It can be used in compatible UAE low-voltage installations when the circuit voltage, frequency, load and wiring arrangement match the product specifications. UAE buildings commonly operate on a nominal 230 V, 50 Hz single-phase supply, but suitability must be confirmed by a qualified electrician. Installation should follow ABB instructions, applicable IEC requirements, BS 7671 where adopted, and the regulations of the relevant UAE authority or utility.

Yes, the 20AX rating is intended to accommodate compatible lighting applications, including circuits that may create higher switching inrush than basic resistive loads. For LED drivers, fluorescent ballasts or multiple luminaires, the total wattage alone is not sufficient for selection; the electrician should verify inrush current and the maximum number of drivers permitted by the switch and lighting manufacturer.

It may control compatible fixed loads within its electrical rating, but equipment suitability must be checked individually. Water heaters, fans, pumps and motors can have different current, isolation, overload protection and inrush requirements. High-load appliances may require a dedicated isolator, fused connection unit, contactor or higher-rated device rather than direct switching through this product.

Installation should be completed by a qualified electrician with the supply isolated, locked out where appropriate and verified dead. The electrician should identify the incoming and outgoing conductors, connect them only to the terminals shown in the ABB wiring diagram, confirm the LED connection, tighten terminals to the specified torque and ensure no bare conductor remains exposed. After fitting the switch to a compatible box, continuity, insulation resistance, polarity and functional tests should be performed before energising the circuit.

Because this is a double-pole switch with an LED indicator, its terminal requirements may differ from those of a standard single-pole light switch. A neutral conductor may be switched or required for the indicator arrangement, depending on the approved circuit configuration. The electrician must check the terminal markings and ABB wiring diagram rather than relying on conductor colour or assumptions.

Compatibility depends on the wall box format, mounting centres, box depth, cable capacity and the associated ABB Inora plate or frame configuration. Before installation, confirm the product dimensions and required accessories against the box already installed. Adequate depth is particularly important for a double-pole mechanism because it may require more wiring space than a basic single-pole switch.

Yes, the Starry Black finish is suitable for modern villas, apartments, offices, hotels, retail spaces and other interior projects where dark electrical accessories complement the design scheme. The small-rocker format provides a compact appearance, while the LED improves visibility. For project consistency, verify that matching ABB Inora sockets, plates and accessories are available in the same finish.

Do not assume that the switch is weatherproof or suitable for exposed outdoor use unless the official ABB documentation states an appropriate IP rating. For gardens, balconies, wash areas, temporary construction locations or dusty and wet environments, use a correctly rated weatherproof enclosure or an outdoor switch with the required IP protection. Installation must also account for condensation, direct sunlight, dust and water exposure.

Contractors should confirm the load type and inrush current, circuit voltage, protective device rating, cable size, double-pole isolation requirement, wall-box compatibility, LED function and required finish. They should also review the approved material submittal, project specifications, local authority requirements and ABB technical documentation. A sample installation can help verify appearance, box depth and coordination with other Inora wiring accessories.

Isolate the circuit before inspection or maintenance. Clean the visible surface with a soft, dry or slightly damp cloth and avoid solvents, abrasive cleaners and excessive water, which may damage the finish or enter the mechanism. If the rocker feels loose, the LED stops operating, overheating is noticed or discoloration appears, stop using the circuit and have the switch and connected load inspected by a qualified electrician.

The ABB Inora BL111S-885 combines double-pole switching, a 20AX rating, LED indication, a compact small rocker and a contemporary Starry Black finish. These features make it relevant to residential, hospitality and commercial fit-out projects requiring coordinated wiring accessories and clear local control. Final selection should always be supported by electrical load calculations, approved project specifications and compliance with applicable UAE installation regulations.
