201 Single-Pole Thermal-Magnetic Circuit Breakers

E-T-A Circuit Breakers 201 Single-Pole Thermal-Magnetic Circuit Breakers are designed for precision overcurrent protection in demanding industrial environments. The 201 features a tease-free, trip-free, snap-action mechanism housed in a compact, narrow-profile design with recessed terminals and standard DIN rail mounting. Designed for intuitive use, this E-T-A device features a two-button operation: a black push button for switching on and resetting, and a separate red manual release button for safe, manual disconnection. By being fully resettable, the 201 provides significantly higher system availability than conventional blade fuses, following a trip due to overcurrent or a short circuit. This versatile circuit breaker supports a wide current rating range from 0.05A to 16A and carries worldwide approvals, including VDE, UL 1077, and CSA. With voltage ratings up to 250V_AC and 80V_DC, the 201 is an ideal solution for industrial automation and process control applications.
