ABB Inora 1 Gang 2 Way 10AX Switch Starry Black BL105-885

“1 gang” means the switch operates one circuit. “2 way” means it can be connected with a second two-way switch to control that circuit from two positions. “10AX” indicates a 10-amp switch rating tested for lighting loads, including loads that can create higher switching currents than basic resistive loads. The connected load and driver inrush current must remain within ABB’s specified limits.

Two-way switching is commonly installed in villas, apartments, offices, hotels and other UAE buildings. Typical locations include opposite ends of corridors, the top and bottom of staircases, bedrooms with switches at the entrance and bedside, and rooms with more than one access point.

A two-way switch can generally be wired for one-way operation by using the common terminal and one switched terminal. The exact terminal arrangement should be checked on the product markings or ABB wiring instructions. Installation should be completed by a qualified electrician rather than relying only on generic wiring diagrams.

For two-way control, two compatible two-way switches are connected using the common and traveller terminals. The permanent live supply is connected at one switch, the traveller conductors run between both switches, and the switched live to the luminaire is connected at the second switch. Terminal labels can vary, so the markings supplied with the switch must be followed. Isolate and verify the circuit is dead before installation, and use a qualified UAE electrical professional.

A conventional mechanical two-way switch normally switches the live conductor and does not usually require a neutral connection at the switch. However, the actual wiring arrangement must be confirmed from the ABB terminal markings and the project drawings. Neutral conductors should never be connected to switching terminals unless specifically required by the manufacturer.

The switch can be used in many LED lighting circuits, but the total wattage alone is not sufficient for selection. LED drivers can produce a high inrush current when switched on, particularly where several fittings are connected to one circuit. The electrician or electrical engineer should check the number of luminaires, driver specifications, inrush current and ABB switching limits before installation.

This product is principally intended for switching suitable lighting circuits. It should not be used as a substitute for a socket outlet, fan speed controller, isolator or heavy-load control switch. Motors, pumps, water heaters and other high-load equipment may require dedicated isolators, contactors or control devices selected according to their current and starting characteristics.

It is suitable for consideration in UAE residential and commercial projects when its electrical rating, wiring method and mounting system match the approved project specification. Installation must comply with applicable local authority requirements, approved electrical drawings and relevant UAE wiring regulations. For regulated projects, the consultant or contractor should confirm product approval and documentation before procurement.

Use in kitchens or bathrooms depends on the installation zone, exposure to moisture and the required enclosure protection. Unless an appropriate IP rating is confirmed for the complete installed assembly, it should be treated as an indoor switch for dry locations. Outdoor, wash-down or high-humidity areas require a suitably rated weatherproof enclosure or switch system compliant with the project requirements.

Contractors should verify that the wall box, mounting centres, box depth, cable capacity and fixing arrangement are compatible with the ABB Inora assembly. The box should be level, firmly secured and flush with the finished wall. Conductors must have sufficient length for termination without overcrowding, and the decorative surface should be protected during painting and finishing work.

Cable size, conductor type and circuit protection must be selected from the connected load, installation method, ambient temperature, grouping and local regulations. The switch rating does not replace the need for correctly rated MCB or RCBO protection. Fixed wiring should use approved cables, suitable earthing arrangements and properly terminated conductors in accordance with the project design.

The Starry Black finish works well with dark door hardware, black lighting fixtures and modern wall finishes in villas, apartments, offices, retail spaces and hotels. For multi-unit construction projects, contractors should confirm finish samples and maintain the same ABB Inora range across switches and accessories to achieve a consistent appearance.

This model is an on/off two-way switch and does not provide dimming by itself. A compatible dimmer and an approved wiring configuration are required for adjustable light levels. The lamps and LED drivers must also be dimmable and compatible with the selected dimmer technology.

Switch off the circuit before inspection or maintenance. Clean the visible surface with a soft, dry or slightly damp cloth, and avoid abrasive pads, solvents and strong chemical cleaners that may damage the Starry Black finish. If the switch becomes loose, overheats, crackles, discolours or operates intermittently, stop using it and have the circuit inspected by a qualified electrician.
