From the supplier

Function

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.

Application

Industry, medical, EV charger, elevator, etc

Conforms to standard

IEC/EN61008-1, IEC/EN62423

Detection residual current type

AC+A+ smoothing DC +F+ high frequency signal (1K Hz)
