CM1 Kompaktleistungsschalter

Wenzhou City POJAL Electric Co.,Ltd. PJM1-630L low- voltage type seriesCM1 moulded case circuit breaker (hereinafter referred to as “Breakers” ) are one of novel breakers designed and developed with internationally advanced technique. These breakers feature small size, high breaking capability, short flashover (zero flashover for partial specifications) and anti-vibration.Breakers are provided with devices to protect circuits and power units from damage caused by overload, short circuit or under voltage. They are ideal products applied in land and vessels. These breakers can either be vertically or horizontally installed. These breakers are in conformity with the standards as follows: IEC60947-1 and GB/T14048.1 General Provisions IEC60947-2 and GB/T14048.2 Low-voltage breaker IEC60947-4 and GB/T14048.4 Contactor and motor starter IEC60947-5.1 and GB/T14048.5 Electromechanical control circuit devices Usual service condition: Altitude 2000m or below;Ambient temperature on higher than +40 centigrade +(45 centigrade for marine products) and no lower than -5centigrade;With resistance against moist air;With resistance against salt fog and oil fog;With resistance against mould; Max gradient:±22.5° Reliably work when suffering normal vibration of the vessel; Safely work during earthquake (4g); In medium free of explosion hazard, no air sufficient to corrode metal and damage insulation, no conductive dust; In a position free of invasion from rain and snow. Application and maintenance: Various characteristics and accessories of the breaker have been fixed by the manufacturer and shall not be arbitrarily adjusted in use.
