ABB Inora 1 Gang 1 Way 20AX Switch Starry Black BL110-885

“1 gang” means the switch has one control rocker, while “1 way” means it operates one circuit from one location. The 20AX marking indicates a 20 A switch rating designed to accommodate the higher inrush currents that can occur with certain lighting loads. The connected load must still be checked against the circuit design, protective device and manufacturer requirements.

It can be used in compatible UAE residential, commercial and hospitality projects where the electrical system, back box, wiring method and connected load match the switch specifications. UAE supplies are commonly 230 V at 50 Hz, but suitability must be confirmed by the project electrical engineer or a licensed electrician in accordance with the relevant local authority regulations, approved drawings and project specifications.

The switch is suitable for single-point control of compatible lighting circuits in villas, apartments, offices, shops, hotels and other indoor spaces. Typical applications include controlling ceiling lights, wall lights or grouped luminaires from one entrance point. It should not be used as a substitute for a dedicated isolator, motor controller, dimmer or high-load appliance switch unless the complete application is specifically approved.

No. A one-way switch is intended to control a circuit from one location only. For controlling the same light from two positions, such as at both ends of a corridor or at the top and bottom of a staircase, a suitable two-way switching arrangement and compatible switches are required.

Installation should be completed by a qualified electrician. The circuit must be isolated at the distribution board, locked out where applicable and tested to confirm it is de-energised. The live supply and switched-live conductors are then connected to the correctly identified terminals, the conductors are secured without exposed copper, and the switch is fitted to a compatible wall box. Terminal identification and tightening requirements should be verified from the ABB product instructions before energising and functional testing.

A conventional mechanical one-way switch normally interrupts the live conductor and generally does not require a neutral connection at the switch position. However, the actual wiring arrangement must follow the terminal markings, ABB instructions and the approved circuit design. Neutral and earth conductors must be terminated or continued safely as required by the installation.

Use a compatible single-gang wall box with adequate depth for the switch mechanism, terminals and conductor bend radius. Compatibility should be checked against the ABB Inora mounting system and the project’s flush-mounted or surface-mounted box before installation. Do not force the mechanism into a shallow or incompatible box, as this can damage conductors or prevent the faceplate from sitting correctly.

It may be used with compatible LED lighting circuits, subject to the total load and the inrush current produced by the LED drivers. Multiple LED drivers can generate a brief starting current significantly higher than their normal operating current. For larger lighting groups, the electrician or electrical engineer should check the driver data and consider using a contactor or relay rather than switching the complete load directly.

It should not automatically be selected for air conditioners, water heaters, pumps or other heavy loads based only on the 20AX marking. Such equipment may require a double-pole isolator, fused connection unit, contactor, motor-rated control device or a higher-duty switch. Selection must consider running current, starting current, pole configuration, isolation requirements and applicable UAE authority rules.

This product should be treated as an indoor wiring accessory unless ABB documentation confirms a suitable ingress-protection rating for the intended environment. For gardens, balconies, external walls, wash areas or dusty construction zones, install an appropriately rated weatherproof enclosure or choose a dedicated outdoor switch with the required IP rating.

Contractors should verify model BL110-885, one-gang one-way operation, 20AX rating, Starry Black finish, wall-box compatibility, circuit load, conductor size and required quantity. They should also compare the item with the approved material submittal, electrical drawings, finish schedule and local authority requirements to avoid mismatched switch types or colours during fit-out.

After fitting, the electrician should confirm secure terminal connections, correct polarity, continuity of protective conductors where applicable, insulation integrity and proper switch operation. The faceplate should sit level without trapping wires, and the circuit should be labelled correctly at the distribution board. Testing and documentation should follow the project specification and the requirements of the relevant UAE electrical authority.

Isolate the circuit before maintenance and clean the surface with a soft, dry or slightly damp cloth. Do not use abrasive pads, solvents or strong chemical cleaners, as they may damage the Starry Black finish. Replace the switch if it develops cracking, overheating, discoloration, loose operation, arcing sounds or intermittent switching, and have the circuit inspected by a qualified electrician.
