Class B leakage circuit breaker: Class B leakage circuit breaker can reliably protect sinusoidal AC signals, pulsating DC signals and smooth signals. It has higher design requirements than Type A leakage circuit breaker and is guaranteed under the following conditions.
(A) Same as type A
(B) Residual sinusoidal alternating current up to 1000Hz
(C) The residual AC current is superimposed with a smooth DC current of 0.4 times the rated residual current
(D) Residual pulsating DC current plus 0.4 times the rated residual current or 10mA smooth DC current (whichever is greater)
(E) Residual DC current produced by the following rectifier circuits:
Suitable for 2-pole, 3-pole and 4-pole residual current circuit breakers, line-to-line half-wave bridge connection
