8.2.2 Selection creep age breaker
8.2.2.1 The creep age protection switch consists of creep age, zero-phase current mutual
inductance and automatic switch. It is applicable to AC 60Hz, single-phase, 220V or three-
phase, 380V. It can prevent person from getting an electric shock and protect device from creep
age. In normal case, it can provide conversion for circuit.
