... A noncontinuous load.” Frequency Rating 40 A The standard-rated frequency for circuit breakers is 60 Hz, but Square circuit breakers can be applied systems without thermal magnetic rerating. Other frequencies can affect the thermal, magnetic and 15 A short-circuit tripping characteristics of circuit breakers. ...
Page 11
... At frequencies above 60 Hz, the interrupting rating of thermal-magnetic circuit breakers is less than the 60 Hz interrupting rating. Unless specifically marked for use of 400 Hz systems, the interrupting rating of Square D circuit breakers is reduced to 1/10th of the 60 Hz interrupting rating. Magnetic Tripping Performance At frequencies above 60 Hz more current is necessary to magnetically trip a circuit breaker than ...
