ESM1 LE series moulded case circuit break with residual current protection. Rated insulation voltage is 800V. It applies to circuit of AC 50Hz , rated working voltage 400V and rated working current up to 630A ,for infrequent switch over and infrequent start of motor. With overload, Short circuit and under-voltage protection,it can protect circuits and power-supply equipment from damage, can also be used for protection from damage and any potential fire hazard caused by long existing earth fault which can not be detected by over-current protection. The value of residual current is selectable.
