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 ESB25-30N-06 uses a 230–240 V AC/DC control circuit to operate its three normally open main contacts, allowing three 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, heating, motor control and electrical distribution systems.
Typical Applications
- Residential and commercial lighting control.
- Building automation and energy-management systems.
- Electric heating and resistive load switching.
- Single-phase and three-phase motor switching.
- Distribution boards and electrical control panels.
- Industrial control and automation systems.
