Reliable Switching for Building and Industrial Loads

Installation contactors provide electrically controlled switching for loads that need to be operated automatically or remotely. The ABB ESB25-40N-07 uses a 400–415 V AC/DC control circuit to operate its four normally open main contacts, allowing multiple conductors or phases to be switched simultaneously from a compatible controller or automation system.

The ESB25..N series is designed for building installations as well as industrial environments. Its hum-free operation, low power consumption, integrated overvoltage protection and modular DIN rail construction make it suitable for modern building automation, lighting, heating, motor control and electrical distribution systems.
