Why Choose the ABB EN40-31N-01 Installation Contactor?
The ABB EN40-31N-01 is a compact and reliable 4-pole installation contactor with manual override designed for switching electrical loads in residential, commercial and industrial applications. As part of the ABB EN40..N installation contactor series, it combines a 40 A class design with three normally open and one normally closed main contact and a 24 V AC/DC control circuit.
The EN40..N series provides flexible electrical and manual control through a built-in toggle switch for manual or automatic operation. Hum-free operation, low power consumption and integrated overvoltage protection make the series particularly suitable for distribution boards, building automation systems and industrial control panels.
With a 3NO/1NC contact configuration, a 24 V AC/DC control circuit and four-pole construction, the EN40-31N-01 provides versatile switching where both normally open and normally closed functions are required. Its compact three-module format enables straightforward DIN rail integration into electrical installations.
