The ABB ESB63-40 is a high-performance modular contactor designed for switching and controlling three-phase loads in residential, commercial, and industrial applications.

Part of ABB’s ESB series, this device is engineered for DIN rail installation inside electrical distribution boards and control panels.

It features a 230V AC/DC coil (40–450 Hz) and a 4-pole configuration (3NO main contacts + 1NO auxiliary contact 13-14), making it ideal for controlling resistive loads, motors, lighting systems, heating systems, and automation circuits.

The compact modular design ensures easy integration into standard panels while maintaining high switching reliability and long operational life.
