ABB Millenium 1 Gang 1 Way 45A Double Pole Switch with LED Silk Black AM17744-SB

Double-pole operation switches the live and neutral conductors together. This provides more complete isolation of a compatible single-phase fixed load than a single-pole switch, subject to correct wiring and the requirements of the applicable UAE electrical authority. The protective earth conductor must remain continuous and must not be switched.

The switch may be used for compatible fixed appliances or circuits whose operating current, voltage, load characteristics and manufacturer requirements are within the switch rating. Typical applications can include selected water heaters, cooking appliances and other high-current fixed equipment. Suitability must be confirmed from the appliance nameplate, starting or inrush current, cable size, protective device and local electrical design requirements.

The switch is rated at 250V AC and is generally compatible with correctly designed UAE low-voltage single-phase installations operating around 230V AC. Final selection and installation must comply with the regulations of the relevant local authority, such as DEWA, ADDC or the applicable emirate utility, together with project specifications and recognised wiring practices such as BS 7671 where adopted.

Installation should be completed by a licensed electrician with the circuit safely isolated, locked off where required and verified as dead. The installer should use a compatible flush box, identify the supply and load conductors, connect them to the marked terminals, maintain earth continuity, tighten terminals to ABB requirements and refit the front plate securely. The circuit should then be inspected and electrically tested before energisation. Always follow the ABB wiring diagram supplied with the product.

Cable size cannot be selected from the 45A switch rating alone. A qualified electrical designer or electrician must consider the connected load, protective device rating, installation method, conductor material, ambient temperature, grouping, insulation type, voltage drop and derating factors. This is especially important in UAE construction projects, where high ambient temperatures can affect cable current-carrying capacity.

The integrated LED provides a visible indication of switch or connected-circuit status. Its exact behaviour can depend on the terminal arrangement and wiring configuration, so the electrician should follow the product diagram to ensure the indicator operates as intended. The LED is useful for quickly identifying circuit status in kitchens, utility areas and building service spaces.

It can provide local double-pole switching for a compatible fixed appliance when its electrical ratings, terminal capacity and installation arrangement meet the appliance manufacturer's instructions and the relevant authority requirements. The project consultant or electrician must confirm whether the application requires a dedicated isolator, switched connection unit, cooker control unit or another specific device.

No. A 1 way switch controls its connected circuit from one switching position. It is not intended to provide conventional two-location control. If operation from two positions is required, a suitable two-way switching arrangement and compatible accessories should be specified.

The listed dimensions are 42 x 86 x 86 mm, and the unit is designed for flush mounting. Before installation, check the wall box dimensions, available internal depth, cable bending space and compatibility with the ABB Millenium plate or accessory system. Adequate box depth is particularly important for safely terminating larger conductors used on higher-current circuits.

Yes, it is suitable for consideration in residential, commercial, hospitality and premium interior fit-out specifications where a Silk Black electrical accessory is required. Contractors should coordinate the switch location, flush box, wiring route, appliance load and final finish before closing walls. The model number AM17744-SB should also be included in material submittals to help maintain finish and accessory consistency.

An ingress-protection or weatherproof rating is not stated in the supplied product information. It should therefore not be assumed suitable for exposed outdoor, wet or dusty locations. Such installations require an enclosure and accessory arrangement with an appropriate IP rating, selected according to the environment and UAE project requirements.

The 45A rating identifies the documented current capacity of the switching mechanism under its specified conditions. The connected load must not exceed the permissible rating, and the complete circuit must also have correctly selected cables and overcurrent protection. For loads with high starting current or unusual duty cycles, suitability should be verified with ABB technical data before installation.

A qualified electrician should check conductor identification, terminal tightness, earth continuity, insulation resistance, polarity, protective-device coordination, secure mounting, rocker operation and LED indication. The circuit should also be labelled where required and included in the project's inspection and testing records before handover.
