The ABB ESB40-40N-06 (1SAE341111R0640) is a 4-pole 40 A modular installation contactor with 4NO main contacts and a universal 230 V AC/DC coil. It fits in any distribution board next to your MCBs and switches single-phase and three-phase loads such as water heaters, lighting circuits, heating and ventilation from a time switch, thermostat, photocell or smart-home controller.
Unlike a conventional magnetic contactor, the ESB..N range runs completely hum-free, draws very little coil power and has integrated overvoltage protection on the coil, so it is the right choice for flats, villas, offices, hotels and hospitals where a quiet panel matters.
Key features
- Silent, hum-free operation – ideal for residential and office boards
- Universal 230 V AC/DC coil with low power consumption
- Integrated overvoltage protection on the coil
- Compact 3 modules (54 mm) modular width, same profile as MCBs
- 4NO contacts rated 40 A (AC-1)
- Suitable for household and industrial installations
- Wide choice of ABB ESB accessories and contact combinations

Frequently asked questions
What is the ABB ESB40-40N-06 used for?
It switches single-phase and three-phase resistive and lighting loads up to 40 A per pole, usually controlled by a time switch, thermostat, push button or smart-home relay – for example a water heater on a daily timer or a building lighting circuit.
Does the ESB contactor make noise?
No. The ESB..N installation contactors are designed for hum-free operation, so they can be installed in residential distribution boards and living areas without the buzzing of standard contactors.
Which coil voltage does it need?
The -06 version has a 230 V coil that works on both AC and DC (50/60 Hz), so it connects directly to a standard 220/230 V supply in Egypt.
How much space does it take in the board?
The ESB40-40N-06 is 3 modules (54 mm) wide on a 35 mm DIN rail.
