Manage your high-current circuits with this contactor from ABB. It can switch currents up to 30A to give you convenient control over large electrical loads. With response times between 4 and 26ms, the device quickly reacts to inputs and delivers efficient appliance management. The three poles work with three-phase voltages for compatibility with common industrial power supplies. A built-in auxiliary contact means the contactor signals your control device when your equipment switches, letting you remotely monitor your hardware for efficient operations.
