This standard is applicable to mechanical switching devices designed as ""circuitbreakers for equipment"" (CBE) intended to provide protection to circuits within electrical equipment. NOTE 1 The term ""equipment"" includes appliances NOTE 2 The protected components are usually motors, transformers, internal wiring, etc. CBEs may have a rated short-circuit capacity higher than that required for overload conditions and may, in addition, have a conditional short-circuit current rating in association with a specified short-circuit protective device (SCPD). This standard is also applicable to switching devices for protection of electrical equipment in case of un
