ABB Inora 1 Gang 1 Way 20AX Double Pole Switch with Illumination, Small Rocker Classic Grey BL111S-G

One gang means the accessory has one switch control. One way means it controls a circuit from a single location rather than from two separate positions. DP stands for double pole, indicating that the switch is designed to disconnect both the live and neutral conductors when correctly installed. This provides more complete isolation than a standard single-pole switch.

The 20AX marking identifies the switch's current and load-switching classification. The AX designation is commonly used for switches designed to handle loads with higher starting or inrush current, subject to the manufacturer's specified voltage, load type and installation conditions. Circuit load, cable size and protective-device rating must still be checked by a qualified electrician before installation.

The integrated LED provides a visible indication that can help users identify the switch position or circuit status. The exact LED operating mode depends on the product's internal configuration and wiring arrangement. Installers should follow the terminal markings and ABB wiring instructions rather than assuming whether the LED operates as an ON indicator or a locator light.

This switch may be used as a local control or isolation point for compatible fixed electrical loads, including selected water heaters, ventilation equipment, lighting circuits and other appliances within its rated capacity. Suitability depends on voltage, steady current, starting current, power factor and the equipment manufacturer's isolation requirements. It must not be selected only by comparing appliance wattage with the nominal switch rating.

It can be considered for UAE residential, commercial and construction projects when its marked voltage, frequency, current rating and certification meet the project specification and local authority requirements. UAE low-voltage supplies are generally 230 V at 50 Hz for single-phase applications, but the rating printed on the product and ABB documentation should be verified before use. Installation must also comply with the applicable emirate's electricity authority regulations and approved project standards.

Installation should be completed by a licensed electrician. The circuit must first be isolated, locked out where applicable and tested for absence of voltage. The supply and load conductors should then be connected to the correctly marked double-pole terminals, with the LED wired only as shown in ABB's diagram. The switch should be secured to a compatible flush or surface box, aligned without trapping conductors, and tested for polarity, continuity, insulation resistance and correct operation before energising.

A double-pole switch normally handles both live and neutral conductors, but the precise terminal arrangement and any LED connection requirements must be confirmed from the markings on the unit and the official wiring diagram. The protective earth conductor must never be switched and should remain properly terminated in accordance with the installation design.

Use a compatible one-gang electrical back box with sufficient depth for the switch body, terminals, conductor bends and any required connectors. Box compatibility, fixing centres and minimum depth should be checked against the ABB Inora product drawing before construction or fit-out work begins. Cable and terminal sizes must suit the circuit design, protective device and manufacturer's permitted conductor range.

It should not be assumed suitable based on the 20AX marking alone. Air conditioners, pumps and motors can produce significant starting current and may require a dedicated isolator, contactor or motor-rated switching device. An electrical engineer should check the equipment's full-load current, locked-rotor or inrush current, duty cycle and manufacturer instructions before specifying the BL111S-G.

Do not install it directly outdoors, in bathrooms, wash areas or other damp and dusty locations unless the completed assembly has the required IP rating and is approved for that environment. Where exposure to water, dust, condensation or UAE outdoor conditions is possible, use a suitable weatherproof enclosure or a purpose-designed outdoor isolator selected by the project engineer.

Contractors should confirm secure termination, correct live and neutral polarity, effective earthing continuity, suitable circuit protection, correct switch and LED operation, firm plate alignment and the absence of exposed copper. Electrical test results should be recorded as required by the project specification, local authority and consultant. The circuit should also be clearly identified on the distribution board schedule and any required local labels applied.

Yes, the ABB Inora BL111S-G can be specified for villas, apartments, offices, retail units and other projects where a Classic Grey small-rocker switch matches the electrical schedule and interior finish. For new construction, designers should coordinate the accessory range, back-box dimensions, wall finishes and circuit ratings before first-fix work. For renovation, installers should verify existing box compatibility, wiring condition, earthing and available box depth.

Keep the faceplate clean using a soft, dry or lightly damp cloth, and avoid solvents, abrasive cleaners and direct water spray. If the rocker becomes loose, the LED behaves unexpectedly, the switch overheats, produces noise or shows discoloration, isolate the circuit and arrange inspection by a qualified electrician. Do not remove the faceplate or tighten live terminals while the circuit is energised.

Before approval for a UAE project, check the product label, ABB technical documentation and supplied certification for the applicable switch standard, commonly IEC 60669-1 or an equivalent adopted standard where relevant. The consultant or contractor should also confirm compliance with the relevant UAE or emirate-level electrical authority rules, project specifications and approved-material requirements. Certification should be verified for the exact BL111S-G model rather than inferred from the brand or product range.
