AC DC Mini MCCB Molded Case Circuit Breaker 3P 4P

ERM1E series moulded case circuit breaker(hereinafter referred to as the circuit breaker),is suitable for occasional conversion and motor protection under the circuit of AC 50Hz,60Hz,rated insulation voltage of 800V,rated operational voltage of 400V and rated operational current to 800A.Circuit breaker has functions of overload long time delay inverse time,short time delay inverse time of short circuit,short time delay definite time of short circuit,short circuit instant,under-voltage protection,residual current protection(optional) and open phase protection function (optional),and can also prevent the line and power equipment from being damaged.The circuit breaker has complete and precise protection features,can improve power supply reliability and avoid unnecessary power outages.The ‘Z.B’ type control has communication interface,and can be ‘four control’ to mee the requirement of control center and automation systems. The leakage circuit breaker ca be classified into two types of M(moderate high breaking) and H(high breaking) according to the rated limit short circuit breaking capacity(Icu).Is has features of small volume,high breaking,short flashover and vibration resistance,etc. It can be installed vertically (vertical assembly) or horizontally (horizontal assembly). The reverse incoming line of circuit breaker shall not fall into the line is not acceptable,i.e.,it’s only allowed to connect power line of 1,3,5 and 2,4,6 of load line.
