ABB Inora 1 Gang 1 Way 20AX Switch White BL110

“1 gang” means the switch has one control rocker. “1 way” means it operates one circuit from a single switching point. “20AX” identifies the switch rating and indicates suitability for switching compatible lighting loads, including certain fluorescent or inductive lighting circuits with inrush current. The connected load, voltage and lighting-driver characteristics must remain within the switch and manufacturer-specified limits.

The BL110 is relevant to UAE villas, apartments, offices, shops and other indoor projects where a compatible 20AX one-way lighting switch is specified. UAE low-voltage supplies are generally 230 V, 50 Hz, but installers must verify the product markings, circuit design and project requirements before use. Installation should follow applicable UAE electrical regulations, local authority requirements and approved project specifications.

It is primarily intended for controlling one compatible lighting circuit from one location, such as a room light, corridor light, office lighting group or shop lighting circuit. It may also be considered for other fixed loads only when the load type, operating current and inrush characteristics are compatible with the switch rating. It should not be used as a socket outlet, dimmer, motor controller or double-pole isolator.

It can be used with compatible LED lighting circuits when the steady-state current and driver inrush current are within the switch manufacturer's permitted limits. LED drivers can draw a high momentary current at startup, so the total lamp wattage alone is not enough to confirm compatibility. For large LED groups, contractors should check the driver data and consider a suitably rated contactor or relay where required.

Installation should be completed by a qualified electrician. Isolate and lock off the circuit, confirm it is de-energised with an approved tester, identify the permanent live and switched-live conductors, and connect them to the terminals indicated on the switch. Secure the mechanism to a compatible flush or surface back box, align the faceplate, restore power and test operation. Follow the terminal markings and ABB installation instructions supplied with the product rather than relying only on generic wiring diagrams.

A conventional mechanical one-way switch normally interrupts the live conductor and commonly uses a permanent live input plus a switched-live output; a neutral connection is generally not made to the switch mechanism. However, wiring arrangements can vary, so the electrician must follow the BL110 terminal markings and the approved circuit design. The neutral should never be used as the switched conductor.

Use a back box and fixing arrangement compatible with the switch dimensions, mounting centres and project wiring system. The box must provide enough depth for terminals, conductor bending radius and safe cable management without crushing insulation. Because exact back-box dimensions are not included in the available product data, verify the ABB datasheet or measure the supplied unit before first-fix work or bulk procurement.

No. A one-way switch is intended to control one circuit from one location. To control the same light from two locations, such as at both ends of a staircase or corridor, use a compatible two-way switching arrangement. Intermediate switches may also be required when control is needed from three or more locations.

The available product information does not state an IP rating, so it should not be assumed suitable for exposed outdoor, wet or dusty locations. For bathrooms, utility areas, balconies and external installations, select equipment with the required IP protection and install it in the permitted electrical zone. During construction, protect the switch from water, cement dust, paint, impact and chemical cleaners.

Confirm the required gang and switching configuration, connected-load type, operating current, inrush current, circuit voltage, back-box compatibility, cable size, indoor environmental conditions and desired white finish. Contractors should also check approved material submittals, consultant specifications, local authority requirements and the latest ABB technical documentation. Where a particular standard or certification is mandatory, verify it from the product marking and conformity documents before approval.

Wall switches are commonly assessed against standards such as IEC or BS EN 60669-1, while the complete installation must comply with applicable UAE wiring regulations, local electricity authority rules and project requirements. Compliance should not be inferred from the product name alone. Review the BL110 label, ABB datasheet and available conformity certificates to confirm the exact standards applicable to the supplied model.

It should not automatically be specified as an appliance isolator. The BL110 is described as a 1-gang, 1-way 20AX switch, and a one-way switch may disconnect only one conductor. Fixed appliances may require a double-pole switch, fused connection unit or dedicated isolator with a suitable load category and contact separation, depending on the equipment and UAE project regulations.

Isolate the electrical supply before inspection or maintenance. Clean the faceplate with a soft, lightly damp cloth and avoid solvents, abrasive pads or excessive water. Periodically check for heat discoloration, cracking, loose mounting, unusual noise, arcing or intermittent operation. Any damaged or overheating switch should be replaced by a qualified electrician after the circuit load and terminations have been checked.
