ABB-ESB series building contactorsDetailed product description：

ABB's ESB building contactors are suitable for achieving automatic control of building equipment, especially for switching and controlling lighting, heating, ventilation, water pumps, heat pumps, and other equipment. It can be installed on a 35mm guide rail.

Features:
Silent electromagnetic operating mechanism. Switch position indication. Contains surge voltage absorber. Additional auxiliary contacts. Enhance the capacity and lifespan of the switch. Open large-scale wiring method.
Structure:
ESB24、 40 and 63 are equipped with diode rectifiers and are AC/DC operating systems, with no noise at all when closed. It is also equipped with a varistor to protect the coil from surge voltages up to 5KV, thus suppressing electromagnetic system interference voltage. And the contactor can be combined with PLC for use. The contacts inside the contactor are the main contacts and can also be used as auxiliary contacts, which are not limited to switch control signals. The half modulus wide bipolar auxiliary contact EH04 can be installed on ESB24, 40, and 63.
