ABB Inora 1 Gang 2 Way 20AX Switch Starry Black BL112-885

“1 gang” means the switch has one control rocker for one lighting circuit. “2 way” means the circuit can be controlled from two separate switch positions, such as at both ends of a corridor or at the top and bottom of a staircase. “20AX” indicates a 20-ampere switch rating intended to handle lighting loads, including the higher switching currents associated with some fluorescent or inductive lighting circuits, subject to the connected load and applicable electrical regulations.

This switch is suitable for residential villas, apartments, offices, hotels, retail spaces and other commercial interiors in the UAE. Typical applications include bedrooms with entrance and bedside controls, corridors, staircases, meeting rooms and large living areas where convenient two-location lighting control is required.

Yes. A two-way switch can normally be wired for one-way operation by using the common terminal and one of the switched terminals. The exact terminal markings and wiring diagram supplied with the product should be followed, and installation should be completed by a qualified electrician.

Isolate and verify the electrical supply before installation. Mount the switch mechanism in a compatible flush or surface back box, connect the incoming live conductor to the common terminal, and connect the switched live or two strapper conductors according to the required one-way or two-way circuit arrangement. Maintain earth continuity, secure all terminals to the manufacturer’s specified torque, fit the faceplate evenly and test polarity, insulation, continuity and switching operation before energising the circuit.

A conventional two-way lighting circuit requires two compatible two-way switches connected by two strapper conductors, with the permanent live and switched live arranged through the common terminals. Cable selection, conductor identification and termination must comply with the approved project design and local electrical requirements. A neutral conductor is generally not connected to a conventional mechanical switch, although project wiring practices may require a neutral to be available in the switch box for future controls.

It can be used to switch compatible LED lighting circuits, provided the total load and LED driver inrush current remain within ABB’s applicable switching limits. LED drivers can create a brief startup current significantly higher than their normal operating current, so large groups of LED fittings should be assessed by the electrical consultant or electrician rather than selected only by their total wattage.

This product is primarily intended as a lighting switch and should not automatically be treated as an appliance isolator or socket control switch. Air conditioners, water heaters, pumps and other high-load equipment may require double-pole isolation, motor-rated switching, contactors or dedicated control devices. Use it only where the equipment design, ABB technical documentation and local regulations confirm suitability.

Yes. The Starry Black finish complements contemporary residential, hospitality and commercial interiors, especially dark hardware, black metalwork and modern decorative themes. During construction, the faceplate should be protected from paint, plaster, cement dust, cleaning chemicals and abrasive tools to preserve its appearance.

Use a back box that is compatible with the ABB Inora mounting format, fixing centres and mechanism depth. The box should provide sufficient space for conductor bending and secure terminations without compressing the wiring. Confirm the product dimensions and back-box requirements from the ABB datasheet or approved project submittal before wall chasing, blockwork closure or gypsum-board completion.

Do not assume outdoor or wet-area suitability unless the confirmed product documentation provides the required IP rating. For bathrooms, balconies, gardens, plant rooms or exposed areas, the switch location, enclosure and ingress-protection rating must comply with the applicable zone and environmental conditions. A suitably rated weatherproof enclosure or dedicated outdoor switch may be required.

Installation should follow the applicable regulations of the relevant UAE electricity authority and municipality, together with the project specification and recognised standards such as BS 7671 where adopted. Requirements can differ between emirates and developments, so a UAE-licensed electrical contractor should verify circuit protection, conductor size, earthing, back-box installation, testing and authority approval requirements.

Contractors should verify the model number BL112-885, 20AX lighting-circuit rating, required one-way or two-way function, back-box compatibility, terminal arrangement, finish approval, load type, LED driver inrush current and environmental conditions. Samples and technical submittals should also be coordinated with the consultant, interior designer and MEP drawings before bulk installation.

Switch off the circuit before inspection or maintenance. Clean the faceplate with a soft, dry or slightly damp cloth and avoid solvents, abrasive pads and strong chemicals. Periodic electrical inspection should check for loose mounting, discoloration, overheating, unusual sounds or intermittent switching; any damaged or overheating unit should be isolated and assessed by a qualified electrician.
