FAQ
-
What is this accessory used for?
It's a genuine ABB DIN-rail/panel accessory used alongside compatible ABB switchgear (breakers, contactors, enclosures) — check the Technical Specifications table for the exact compatible device range.
-
Is this compatible with other ABB equipment I already have?
Genuine ABB accessories are designed for ABB's own matching device ranges — confirm the exact series/model compatibility in the product's Technical Specifications before ordering, since accessory ranges are model-specific.
-
Can I fit this myself?
Simple panel accessories like pilot lamps and selector switches can often be fitted by a competent person, but anything involving live wiring or a distribution board should be done by a licensed electrician in line with UAE wiring regulations.
-
Does this come with the base device or is it sold separately?
This is sold as a standalone accessory — check the listing and your existing equipment to confirm it's the add-on rather than the complete base unit.
