ABB Inora 1 Gang 1 Way 45A Double Pole Switch with Illumination Starry Black BL179-885

One gang means the plate contains one switch mechanism, while one way means the connected circuit is controlled from a single location. Double pole, or DP, means the switch disconnects both live and neutral simultaneously. This provides more complete isolation than a single-pole switch and is commonly specified for dedicated high-current appliances.

A 45A DP switch is commonly considered for dedicated fixed appliances such as electric cookers, ovens, water heaters and similar high-load equipment. Suitability depends on the appliance nameplate current, starting characteristics, circuit design and manufacturer instructions. The actual connected load must not exceed the switch or circuit rating.

The integrated LED provides a visible indication associated with the switch or connected circuit, helping users identify its operating status. The exact indicator behavior can depend on the product's terminal arrangement and wiring method, so installers should follow the ABB wiring diagram supplied with the unit rather than assume the LED configuration.

It can be used in UAE projects when its marked voltage, current rating and installation conditions match the approved electrical design. Installation should comply with applicable UAE requirements, the relevant emirate authority's regulations, project specifications and current BS/IEC-based wiring practices. Approval requirements should be confirmed with authorities such as DEWA, ADDC or the applicable local utility before project use.

Installation should be completed by a licensed electrician. The supply must be safely isolated, locked out where required and verified dead before work begins. The appropriate conductors are connected to the clearly marked line and load terminals according to ABB's wiring diagram, after which terminal tightness, polarity, insulation resistance, earth continuity and functional operation should be tested before energising.

Cable size cannot be selected from the 45A switch rating alone. A qualified electrical designer or electrician must consider the appliance load, protective-device rating, cable type, installation method, ambient temperature, grouping, route length, voltage drop and thermal insulation. UAE conditions, including high ambient temperatures, may require derating or a larger conductor size under the applicable wiring regulations.

No. This wall switch provides local switching and double-pole isolation for the connected appliance, but it does not replace circuit overcurrent or earth-leakage protection. The circuit should still have correctly rated protective devices, such as an MCB or RCBO, as required by the approved electrical design and local regulations.

Contractors should verify the compatible box dimensions and depth, mounting arrangement, terminal space and cable bending radius. A 45A circuit may use larger conductors that require more room than standard lighting wiring. The box must be securely fixed, aligned with the finished wall, free from plaster contamination and deep enough to avoid compressing or sharply bending conductors.

The switch should only be installed where the product's stated environmental and ingress-protection ratings are suitable. In kitchens or utility spaces, keep it away from direct water, steam and excessive heat. Bathroom and outdoor installations require compliance with electrical zones, IP-rating requirements and local regulations; use an appropriately rated weatherproof enclosure or accessory where exposure is possible.

Double-pole switching disconnects both live and neutral conductors, providing clear local isolation for appliance servicing and maintenance. This is useful in villas, apartments, commercial kitchens, staff accommodation and hospitality fit-outs where dedicated high-load equipment must be safely controlled. The LED also supports quick visual identification during operation and maintenance.

It may be suitable as a cooker control switch when the cooker circuit's design current is within the switch's 45A rating and the appliance manufacturer permits this arrangement. The electrician must also confirm cable capacity, protective-device coordination, isolation requirements, mounting location and any need for a separate cooker connection unit.

After installation, a qualified electrician should inspect conductor termination and torque, verify polarity and protective-earth continuity, and perform the electrical tests required by the project and local authority. The switch and LED should then be functionally tested under controlled conditions. Test results should be recorded as part of the circuit commissioning documentation.

Isolate the circuit before maintenance and clean the faceplate with a soft, dry or slightly damp cloth. Do not use abrasive pads, solvents or aggressive chemicals, as they may damage the Starry Black surface. Periodic electrical inspection should check for discoloration, unusual heat, loose mounting, buzzing or a burning smell; any such issue requires immediate assessment by an electrician.
