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 250VAC and 80VDC, the 201 is an ideal solution for industrial automation and process control applications.
