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-04 uses a 110–120 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 household applications 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, electrical heating, water heaters, pumps, ventilation equipment and motor control applications.
Typical Applications
- Residential and commercial lighting control.
- Building automation and energy-management systems.
- Electric heating and water-heating systems.
- Single-phase and three-phase motor switching.
- Pump and ventilation control systems.
- Distribution boards and industrial electrical control panels.
