Do not install the breaker in an abnormal environment. Protect the circuit breaker so that the foreign particles,such as dust,concrete or/and iron power, water and other moistures will not enter the breaker. Failture to do so may make the breaker inoperative. Connect the circuit breaker to power supply appropriate to the rating voltage. Failure to do so may make the breaker inoperative or damage it. The breaker is installed in a plastic or metal box on a mounting plate with latches having two fixed positions. Power can be supplied from both the upper and lower contacrts.Terminals allow to connect copper or aluminum conductors.Before connecting standed conductors, they must be tipped using an appropriate tool.
