ABB Inora 1 Gang 2 Way 10AX Switch Classic Grey BL105-G

One gang means the unit has one switch control. Two way means it can be paired with another two-way switch to control the same light from two positions, such as the top and bottom of a staircase. The 10AX designation is a lighting-switch rating intended to account for the higher switching currents that can occur with certain fluorescent, LED-driver and other inductive or capacitive lighting loads. The connected load must still remain within ABB's specified limits.

This switch is suitable for indoor lighting control in UAE homes, villas, apartments, offices, hotels, retail premises and other commercial buildings. Typical applications include bedrooms with two entrances, corridors, staircases and passageways where one light needs to be controlled from two locations. Use in bathrooms, outdoor spaces or damp areas requires an appropriately rated enclosure and compliance with applicable electrical-zone and ingress-protection requirements.

A two-way switch can generally be wired for one-way operation by using the common terminal and one switched terminal. However, terminal markings and the ABB wiring information should be checked before connection. Installation should be completed by a qualified electrician to ensure correct conductor identification, earthing and circuit protection.

For standard two-way control, the permanent live conductor is connected to the common terminal of the first switch, two traveller conductors link the corresponding two-way terminals of both switches, and the common terminal of the second switch feeds the lighting load. The neutral normally runs directly to the luminaire rather than through a conventional mechanical switch. Isolate and verify the circuit is dead before work, follow the terminal markings and ABB instructions, and have the installation tested by a licensed electrical professional.

It can be used with many compatible LED lighting circuits, but suitability depends on the LED driver's inrush current and the total connected load, not only the lamps' combined wattage. Large groups of LED drivers can produce a brief startup current that exceeds the switch mechanism's capability. Check the luminaire or driver data and ABB's technical documentation, and use a contactor or suitable control device when switching larger lighting banks.

The switch is relevant to common UAE residential and commercial lighting applications, subject to confirmation that its marked voltage, frequency, certification and installation conditions match the project requirements. Electrical work should follow the applicable UAE authority regulations, approved project specifications and relevant wiring standards, such as BS 7671 where adopted. Contractors should also confirm requirements with the responsible authority in the emirate, including DEWA, ADDC or the applicable local utility.

Use a compatible single-gang flush or surface back box with sufficient depth for the switch mechanism, conductors and terminal bend radius. Compatibility should be checked against the ABB Inora product dimensions and the project's box standard before ordering. Use approved copper conductors of the correct size, suitable terminals where required, an earth connection, matching mounting screws and appropriate circuit protection.

The BL105-G is primarily intended as a lighting switch. It should not be assumed suitable for socket outlets, water heaters, pumps, air conditioners, large ventilation fans or other heavy or motor-driven loads. Such equipment can have high running or startup currents and may require a correctly rated isolator, double-pole switch, contactor or dedicated motor-control device selected by an electrical engineer.

It should not be installed directly outdoors or in exposed dusty, wet or humid locations unless it is housed in a compatible weatherproof enclosure that provides the IP rating required by the site conditions. UAE heat, dust, UV exposure and moisture can affect indoor wiring accessories. For gardens, balconies, service yards and outdoor construction areas, use purpose-designed weatherproof switching equipment.

Confirm the approved material submittal, model number BL105-G, 1-gang 2-way function, 10AX rating, supply characteristics, faceplate finish, back-box compatibility and required certifications. Contractors should also verify cable sizes, circuit protection, earthing, installation height, coordination with architectural finishes and accessibility requirements. After installation, inspect terminal tightness and polarity, test protective conductors and insulation as applicable, and complete the required functional and circuit tests.

First isolate the electrical supply and verify it is safely de-energised. Common causes include a loose terminal, permanent live or switched live connected to the wrong common terminal, crossed or disconnected traveller conductors, a faulty lamp or LED driver, or incompatibility between accessories. A qualified electrician should compare the wiring with the ABB terminal markings and circuit diagram, then carry out continuity, polarity and functional testing before re-energising the circuit.

Switch off the circuit before cleaning and use a soft, dry or lightly damp cloth on the visible surface. Do not apply abrasive pads, solvents, strong chemicals or excessive water, as these may damage the classic grey finish or enter the mechanism. Periodic electrical inspection should check for discoloration, overheating, cracking, looseness or abnormal operation; any damaged accessory should be replaced rather than repaired on site.
