ABB Inora 1 Gang 1 Way 45A Double Pole Switch with Illumination Royal Gold BL179-PG

1 gang means the faceplate controls one circuit. 1 way means the circuit is operated from one switching location. Double pole, or DP, means the switch simultaneously interrupts both live and neutral conductors, providing more complete isolation than a single-pole switch. The protective earth conductor remains continuous and must not be switched.

This 45A switch is generally used as a local isolating switch for high-current fixed appliances such as electric cookers, ovens, water heaters and certain air-conditioning equipment. Suitability depends on the appliance rated current, starting or inrush current, circuit design and manufacturer instructions. It should not be selected for a load exceeding its 45A rating.

It may be used as a cooker or oven isolator where the calculated design current and the appliance manufacturer's requirements are compatible with a 45A double-pole switch. The electrician must also verify cable size, circuit breaker rating, diversity calculations, mounting position and any local requirement for the isolator to be accessible and located away from direct heat or cooking splashes.

It can be considered for compatible fixed water-heater or air-conditioning circuits, subject to the equipment nameplate current and installation instructions. Air conditioners may have significant starting current and can require a purpose-designed AC isolator, contactor or weatherproof enclosure. For outdoor condensers, use an appropriately rated weatherproof isolator rather than assuming this decorative indoor switch provides environmental protection.

The LED gives a clear visual indication associated with the switch or connected circuit. Depending on the product's terminal arrangement, it may indicate that the circuit is energised or that the switch is on. The installer should follow the ABB wiring diagram supplied with model BL179-PG to obtain the intended indication and should not infer safe isolation from the LED alone.

Installation should be completed by a qualified electrician. The supply must be isolated, locked off where appropriate and proven dead with an approved tester. The electrician should confirm the correct back box, cable conductor size, terminal identification and stripping length, connect live and neutral through the designated double-pole terminals, maintain earth continuity, tighten terminals to ABB's specified torque and refit the plate without trapping conductors. Insulation resistance, polarity, earth continuity and functional tests should be completed before energising the circuit.

Cable and protective-device selection cannot be based on the switch rating alone. The electrician must calculate the design current and consider installation method, conductor material, ambient temperature, grouping, thermal insulation, voltage drop, fault-loop impedance and appliance requirements. The breaker must protect the cable and circuit, while the switch rating must be equal to or greater than the intended load current. Final selection should follow the approved project design and applicable UAE authority requirements.

The 45A double-pole format is relevant to UAE villas, apartments, hotels and commercial fit-outs that require local isolation of higher-load fixed appliances. Before specification, the consultant or contractor should verify the ABB technical datasheet, required product approvals, project specifications and the rules of the relevant UAE electricity authority, such as DEWA or the applicable authority in the project emirate.

It may be installed in suitable indoor locations when permitted by the project design, but placement must account for moisture, heat, steam and splash zones. Do not use it outdoors or in wet, dusty or exposed locations unless ABB confirms an appropriate IP rating and it is installed in a suitable enclosure. Bathroom and wet-area installations must comply with electrical zoning, supplementary protection and local authority requirements.

The contractor should confirm that the wall box is compatible, securely fixed, correctly aligned and deep enough for the heavy-gauge conductors without excessive bending or terminal stress. Cable routes should be coordinated with MEP drawings, fire-stopping must be reinstated where required, and the switch should remain accessible for operation and maintenance. The Royal Gold faceplate should be protected from paint, plaster, grout and abrasive cleaning during finishing works.

No. Although double-pole switching disconnects live and neutral, safe electrical work still requires proper isolation procedures. The correct circuit must be identified, isolated at the distribution board when necessary, secured against reconnection and proven dead using an approved voltage indicator. The LED is a convenience indicator and must never replace formal safe-isolation testing.

Isolate the electrical supply before inspection or cleaning. Wipe the faceplate with a soft, dry or slightly damp cloth and avoid abrasive pads, solvents, acidic cleaners and excessive water, as these can damage the Royal Gold finish or enter the mechanism. Arrange inspection by a qualified electrician if the switch becomes hot, discoloured, loose, noisy, difficult to operate or produces a burning smell.

Check the project switch schedule, appliance load, circuit current, gang and switching requirements, finish, back-box compatibility and LED function against ABB's current technical documentation. Buyers searching for an ABB Inora 1 gang 1 way 45A DP switch with LED should also confirm the model number BL179-PG and Royal Gold finish before ordering, especially when matching other accessories in an existing installation.
