Circuit Breaker System
The ESS20 circuit breaker system selectively protects individual components powered by a 24 V DC switch-mode power supply. Switch-selectable to either 3 A or 6 A rating, the ESS20 may be added to a DIN-rail power supply system to provide advanced circuit protection to sensors, actuators, field bus couplers, and controls. A thermal trip mechanism is controlled by a solid-state switch that actively limits inrush currents to no more than 1.8 times the set rated current of the circuit breaker. The switch also protects against reverse polarity.
