ABB Inora 1 Gang 2 Way 20AX Switch Royal Gold BL112-PG

One gang means the switch has one control rocker for operating a single circuit. Two way means it has common and changeover terminals, allowing one lighting circuit to be controlled from two different positions when connected to another compatible two-way switch. Typical applications include staircases, corridors, bedrooms and rooms with two entrances.

The 20AX marking identifies the switch's rated current category, with the AX designation intended to account for the demanding switching characteristics of certain lighting loads. Actual load suitability depends on the lamp type, driver, ballast, inrush current, supply conditions and ABB's technical limits. The connected load should therefore be checked by a qualified electrical professional rather than selected from wattage alone.

It can be used as an on/off control for compatible LED lighting circuits, subject to the total operating current and the inrush current produced by the LED drivers. Large groups of LED fittings can create a brief start-up current substantially higher than their normal running current, so contractors should confirm driver data and ABB's switching-load guidance before installation.

Two-way switching is commonly specified for villa staircases, apartment corridors, hotel rooms, office passages, majlis entrances and rooms with more than one access point. It improves convenience by allowing the same lighting circuit to be switched from either end of the area.

A two-way switch can generally be wired for one-way operation by using the common terminal and one changeover terminal. Terminal identification must be confirmed on the product, and the connection should be completed by a licensed electrician in accordance with ABB instructions and the approved project wiring diagram.

Installation normally involves isolating and proving the circuit dead, confirming the line and traveller conductors, terminating them at the marked common and changeover terminals, securing the switch to a compatible flush or surface box, and fitting the front plate correctly. The circuit must then be tested for polarity, continuity, insulation resistance and functional two-way operation. Electrical installation should only be performed by a qualified electrician.

A conventional two-way arrangement requires two compatible two-way switches, a permanent line connection, two traveller or strapper conductors between the switches, and a switched line to the luminaire. The neutral normally runs directly to the light rather than through a standard mechanical switch. Conductor identification and wiring methods must follow the approved design and local electrical regulations.

The ABB BL112-PG is a mechanical two-way switch and typically does not require a neutral connection at the switch itself. However, the complete circuit still requires a neutral at the lighting load. Contractors should follow the terminal markings, project drawings and ABB installation documentation rather than relying solely on wire colour.

Yes, the Royal Gold finish is suited to decorative interiors where electrical accessories must complement gold-toned hardware, lighting fixtures or luxury finishes. It can be considered for villas, hotels, reception spaces, executive offices and premium apartments. A physical sample should be reviewed where exact colour coordination is important, as appearance can vary with lighting and surrounding materials.

It may be used in UAE projects when its electrical rating, wiring configuration, back-box compatibility and documented approvals meet the project specification and the requirements of the relevant authority. Contractors should verify compliance documents and installation requirements applicable to DEWA, ADDC, SEWA or the relevant local authority, as well as the project's adopted wiring regulations.

Before specification, confirm the current ABB technical datasheet, conformity documentation and any applicable switch standard, commonly the relevant parts of BS EN or IEC 60669 for household and similar fixed electrical installations. Installation should also comply with the UAE authority requirements, approved project specifications and the wiring regulations adopted by the relevant emirate. The product name alone should not be treated as proof of a particular certification.

It should not be selected for fans, motors, pumps or other inductive equipment based only on its 20AX marking. Such loads may have high starting currents and can require a dedicated isolator, motor-rated switch, contactor or controller. Use the BL112-PG primarily for an approved lighting application unless ABB documentation specifically confirms suitability for the intended load.

Do not install it directly outdoors, in bathrooms, wash areas or other damp and dusty locations unless the complete assembly has an appropriate IP rating and the installation is permitted for that zone. Outdoor UAE conditions can expose accessories to heat, humidity, dust and water ingress, so a suitably rated weatherproof enclosure or outdoor switch should be used where required.

Verify the model number BL112-PG, Royal Gold finish, one-gang two-way configuration, 20AX rating, required quantity, compatible mounting box, plate system, wiring arrangement and project approval requirements. For refurbishment work, also check box depth, fixing centres, cable condition and compatibility with the existing ABB Inora accessories.
