ABB Inora 1 Gang 1 Way 20AX Double Pole Switch with LED Classic Grey BL111-G

One gang means the plate contains one switch control. One way means the connected circuit is operated from a single switching point rather than from two locations. Double pole, or DP, means the switch isolates both the live and neutral conductors simultaneously, providing more complete circuit disconnection than a standard single-pole switch.

The 20AX marking indicates a 20-amp switch with enhanced switching capability for certain lighting loads that may produce high inrush currents, such as fluorescent or LED driver circuits. The connected load, cable size, protective device and installation method must all be checked by a qualified electrician; the 20AX marking should not be treated as permission to connect any appliance or load up to 20 amps without a circuit assessment.

The LED provides a convenient visual indication and may function as a power-status indicator or locator, depending on the switch design and permitted wiring arrangement. This can be useful in plant rooms, kitchens, utility areas, offices and residential service spaces. The installer should follow the ABB wiring diagram supplied with model BL111-G because LED terminal arrangements can vary.

It can be used in compatible UAE residential, commercial and light-duty construction applications when its voltage, frequency, load rating, enclosure location and wiring requirements match the project specification. UAE supplies are generally 230 V, 50 Hz for single-phase circuits. Installation must comply with applicable local authority requirements, project specifications and relevant wiring regulations, such as BS 7671 where adopted.

Typical applications include controlling or isolating compatible lighting circuits, exhaust fans, water heaters, fixed appliances and other electrical loads that benefit from double-pole switching. Final suitability depends on the equipment current, startup current, manufacturer instructions and circuit protection. It is not a substitute for a dedicated isolator where regulations or the connected equipment require a specific isolation device.

No. The BL111-G is identified as a one-way switch, so it is intended to control one circuit from one location. A staircase, corridor or room requiring control from two positions normally needs compatible two-way switches and the appropriate wiring arrangement.

Installation should be completed by a qualified electrician. The circuit must first be isolated at the distribution board, locked out where required and verified dead with an approved tester. The electrician should confirm the terminal identification, connect the live and neutral conductors according to ABB's diagram, terminate the earth conductor correctly, tighten terminals to the specified torque, mount the switch level in a compatible box and test polarity, continuity, insulation resistance, operation and LED function before energising.

Use a compatible single-gang back box with sufficient depth for the switch body, double-pole conductors and safe cable bending. Cable type and conductor size must be selected according to the connected load, installation method, ambient temperature, voltage drop and protective device. UAE construction projects should follow the approved electrical drawings, local authority requirements and the ABB product datasheet rather than choosing cable size from the switch rating alone.

The switch should not be exposed directly to rain, irrigation water, dust or severe outdoor conditions unless it is installed within a suitably rated weatherproof enclosure. For balconies, gardens, workshops and external service areas, select an enclosure with an IP rating appropriate to the location. UAE heat, humidity, condensation and dust exposure must also be considered during product and enclosure selection.

The 20AX rating makes the switch relevant to many compatible LED lighting circuits, including circuits whose drivers create higher inrush currents. However, suitability must be verified against the total steady-state load, driver inrush current, number of fittings and switching frequency. For large LED lighting groups in commercial construction, a contactor or dedicated control device may be required.

Double-pole switching disconnects both live and neutral conductors together, which can improve isolation for maintenance and is commonly specified for selected fixed appliances and building-service circuits. Whether it is mandatory depends on the application, local regulations, authority requirements and project consultant's specification. Protective earthing remains continuous and must never be switched.

It may be a suitable replacement if the existing installation requires a one-gang, one-way, double-pole switch and the electrical rating, terminal arrangement, back-box dimensions and load characteristics are compatible. A qualified electrician should inspect the wiring and circuit protection before replacement. A 20AX DP switch should not automatically replace a two-way switch, cooker control unit, fused connection unit or higher-rated isolator.

Keep the faceplate clean with a soft, dry or lightly damp cloth and avoid solvents, abrasive cleaners and excess water. Periodically check for discoloration, unusual heat, buzzing, loose mounting, intermittent operation or LED failure. If any fault is found, isolate the circuit and have the switch and terminations inspected by a qualified electrician rather than opening or repairing it while energised.

Contractors should verify the approved brand schedule, model number BL111-G, 20AX load requirement, one-way control arrangement, need for double-pole isolation, LED operating mode, classic grey finish, back-box compatibility and environmental conditions. They should also confirm compliance documentation and coordinate the switch with the distribution-board protection, cable schedule, architectural finishes and relevant UAE authority or consultant approvals.
