ABB Millenium 1 Gang 1 Way 45A Double Pole Switch with LED Mocha Brown AM17744-MO

This switch is suitable for compatible high-current, single-phase fixed appliances and electrical circuits where local isolation is required. Typical applications may include water heaters, cookers, selected air-conditioning equipment, and similar loads, subject to the appliance rating, starting current, circuit design, and manufacturer instructions. It must not be used where the connected load exceeds its electrical rating.

Double pole operation means the switch disconnects both the live and neutral conductors at the same time. This provides more complete local isolation than a single pole switch, which normally interrupts only the live conductor. The protective earth conductor must remain continuous and must never be switched.

The 1 gang configuration means the unit has one rocker controlling one circuit. The 1 way arrangement means that circuit is operated from this single switch position. It is not intended to provide two-location switching, such as controlling the same circuit from opposite ends of a room.

Its 250V AC rating is appropriate for consideration on the UAE's nominal 230V, 50Hz single-phase supply. Final suitability depends on the connected load, cable size, protective device, installation location, and project requirements. Installation should comply with applicable UAE electrical regulations and the requirements of the relevant authority, such as DEWA, ADDC, SEWA, or the local utility.

The circuit must first be isolated, locked out where applicable, and tested to confirm it is de-energised. A qualified electrician should install the switch in a compatible flush box, identify the supply and load conductors, and terminate live and neutral according to ABB's wiring diagram and terminal markings. The protective earth must be connected continuously through the approved earthing terminal or box arrangement. Terminals should be tightened to the manufacturer's specified torque before the faceplate is aligned and secured.

Cable and protective-device selection must be based on the actual appliance load, installation method, conductor material, ambient temperature, grouping, voltage drop, fault protection, and applicable UAE wiring rules. The 45A switch rating does not automatically mean that every connected circuit should use a 45A breaker. A qualified electrical engineer or electrician must coordinate the cable, breaker, switch, and appliance ratings.

The integrated LED provides a visible indication of the switch or connected-circuit status, depending on the specified terminal arrangement. This is useful for fixed appliances where operation may not otherwise be obvious. The installer should follow the ABB wiring diagram because the LED's behaviour can depend on how the mechanism is connected.

It may be suitable for a compatible single-phase air conditioner, water heater, or other fixed appliance when the operating and starting currents remain within the device rating and the equipment manufacturer permits this type of local isolator. For motors, compressors, three-phase equipment, or loads requiring a specific isolation category, a dedicated rated isolator or contactor may be required instead.

Yes. Its flush-mounted design conceals the fixed wiring behind the finished wall surface, making it suitable for villas, apartments, offices, hotels, and commercial fit-out projects. The listed overall dimensions are 42 x 86 x 86 mm, with an 86 mm width. Contractors should verify the compatible back-box dimensions, wiring space, wall finish depth, and Millenium accessory compatibility before installation.

The supplied information does not state an outdoor or weatherproof IP rating. It should therefore be treated as an indoor flush-mounted accessory unless ABB documentation confirms otherwise. For balconies, gardens, plant rooms, bathrooms, or other damp and dusty locations, use a suitably IP-rated enclosure or isolator selected for the environmental conditions and UAE project specifications.

A qualified electrician should inspect conductor identification, terminal tightness, earthing continuity, polarity, insulation resistance, protective-device coordination, secure mounting, rocker operation, and LED function. The circuit should then be energised safely and tested under the connected load. Test results and circuit identification should be recorded where required by the project consultant or local authority.

Key specifications include a 1 gang configuration, 1 way control, double pole switching, 45A rated current, 250V AC rated voltage, rocker operation, integrated LED indication, flush-mounted installation, mocha brown finish, and listed dimensions of 42 x 86 x 86 mm. The model number is AM17744-MO and the FEPY SKU is 82768-NOS.

Keep the faceplate clean with a soft, dry cloth and avoid solvents, abrasive cleaners, or direct water spray. If the switch becomes unusually warm, discoloured, loose, noisy, or produces a burning smell, isolate the circuit and arrange an inspection by a qualified electrician. Periodic checks are particularly important on heavily used appliance circuits because loose terminations can cause overheating.
