DC Residual Current Circuit Breaker

Basic Information
  1. Model TSL3-63B

Product Description


TSL3-63B is a kind of circuit breaker with complete update of residual currentdetection, based on current type A RCCB. It can not only effectively protect AC and pulsing DC (A type), the possible compound residual current(F type ) , but also smoothing DC and high frequency residual current(1KHz) .In a circuit consisting of rectifier, inverter, frequency inverter, etc, the leakage current caused in DC loop circuit can be effectively detected and protected.


Industry, medical, EV charger, elevator, etc
