ABB Inora 1 Gang 1 Way 20AX Switch Classic Grey BL110-G

“1 gang” means the faceplate has one switch control. “1 way” means that control operates a circuit from a single switching point. For example, it can switch a room light on or off from one entrance. It is not the correct configuration when the same light must be controlled from two separate locations; that application normally requires two-way switches and suitable wiring.

The 20AX marking identifies the switch rating for AC lighting applications, with the AX classification addressing the demanding inrush characteristics associated with certain lighting loads. The connected load must still remain within the switch rating, cable capacity, protective-device rating and lighting manufacturer's requirements. For LED drivers, contactors or unusually high-inrush loads, an electrical engineer should verify compatibility.

It can be used as an on/off control for many LED lighting circuits when the total operating current and driver inrush current are compatible with the switch rating. Because LED drivers can draw a brief but significant current at start-up, suitability should not be assessed from lamp wattage alone. For large groups of LED fittings, use manufacturer data and consider a suitably rated contactor or relay.

This switch is suitable for indoor lighting-control applications in UAE villas, apartments, offices, retail units, hotels and other commercial interiors, subject to the project's electrical specification. Its classic grey finish can complement contemporary interiors, service areas and coordinated grey wiring accessories. Installation must follow the relevant UAE authority requirements and approved project drawings.

Installation should be completed by a qualified electrician. The circuit must first be isolated, locked out where required and proven dead with an approved tester. The incoming live conductor and switched-live conductor are then connected to the terminals identified on the product, following ABB's wiring diagram. Conductors must be correctly stripped, securely terminated and arranged without damaging insulation before the switch is fixed level to the compatible wall box and tested.

A conventional mechanical one-way light switch generally switches the live conductor and does not normally use a neutral at the switch mechanism. However, the actual terminal markings and ABB instructions supplied with the product must be followed. A neutral conductor must never be connected to a switching terminal unless the approved wiring diagram specifically requires it.

Use a concealed or surface-mounted back box that matches the switch's mounting format, screw centres and required wiring depth. Allow adequate space for cable bends and safe terminal clearance, particularly where larger conductors or multiple cables enter the box. Confirm compatibility from the ABB product documentation or approved project submittal before completing blockwork, drywall cut-outs or conduit installation.

Do not assume that this standard wall switch is weatherproof. For exposed balconies, gardens, rooftops, wash areas or other damp and dusty locations, it must be installed only within a suitably rated weatherproof enclosure if permitted by ABB and the project specification. Select an accessory with an appropriate IP rating for direct outdoor exposure and comply with local environmental and electrical requirements.

Installation should comply with the regulations of the relevant local authority, such as DEWA requirements in Dubai or the applicable authority in the project emirate, together with the approved consultant specification and current wiring rules adopted for the project. Requirements typically cover circuit protection, conductor sizing, earthing, isolation, testing and approved materials. Final selection and installation should be verified by a licensed electrical professional.

No. A one-way switch is intended to control a circuit from one location only. Staircases, corridors, bedrooms with bedside controls and rooms with two entrances normally require a two-way switching arrangement. For control from three or more positions, intermediate switching or an approved control system may also be required.

This product is primarily identified as a 20AX lighting switch and should not automatically be selected as an appliance isolator or socket control. Water heaters, air conditioners and other fixed equipment may require double-pole isolation, higher load ratings, specific contact separation and dedicated protective devices. Use an accessory specified for the appliance and follow the equipment manufacturer's instructions and UAE project requirements.

A qualified electrician should inspect terminal tightness, conductor identification, insulation condition, faceplate alignment and secure mounting. The circuit should then undergo the required continuity, insulation-resistance, polarity and functional tests, along with verification of the protective device and earthing arrangement where applicable. Test results should be recorded as required by the project's inspection and commissioning procedures.

Isolate the circuit before maintenance and wipe the visible surface with a soft, dry or slightly damp cloth. Do not use abrasive pads, solvents or excessive water, as these may damage the finish or enter the mechanism. Replace the switch if it becomes loose, cracked, discoloured, unusually warm or unreliable, and have recurring faults investigated by a qualified electrician.
