ABB ESB63-40N-06 63A Installation Contactor 4NO
The ABB ESB63-40N-06 is a 63A installation contactor with four normally open contacts (4NO) for four-circuit independent switching in UAE building services, commercial lighting, and load management panels. The 4NO configuration allows simultaneous control of up to four separate circuits from a single contactor, simplifying panel design.
Key Features
- 63A rated with 4 NO independent contacts
- Four-circuit switching capability in one device
- 230V AC coil for standard UAE panel supply
- DIN rail mounting for compact panel installation
- Genuine ABB ESB quality

FAQ
-
What does this contactor control?
It's an electrically-operated switch used to make/break a load circuit repeatedly under remote or automatic control — commonly lighting banks, motors, HVAC equipment, or heating loads switched via a timer, BMS, or control relay.
-
Does this need a separate overload relay for motor protection?
Yes, if it's controlling a motor — a contactor alone doesn't protect against sustained overload. Pair it with a compatible thermal overload relay (see ABB's matching TF/TA-series relays) to form a full motor starter.
-
Can I control this contactor with a timer or BMS?
Yes — the coil is designed for remote switching from a timer, PLC, BMS, or control relay rather than direct manual operation, making it suited to automated load switching.
-
Can I install this myself?
No. Contactors are wired into live control and power circuits and must be installed by a licensed electrician in accordance with UAE wiring regulations.
