GeneralWCM1 sereis moulded case circuit breaker (MCCB for short) is one of new type MCCBs researched and developed by using advanced design and manufacture technolgy internationally. The rated insulation voltage is 800V (WCM1-63 is 500V). It applied for infrequent switch of the line of AC 50Hz, rated operation voltage 690V and below (WCM1-63 is 400V), and for infrequent starting of the motor. The MCCB with overload, short circuit and under-voltage protection fitting can protect the line and power device from demage. The MCCB is classfied into four types individually as Type C (low breaking), Type L (standard), Type M (higher breaking), Type H (high breaking according to the rated ultimate short circuit breking capacity (Icu) ranking. The MCCB is small volume, high breaking capacity, short flashover (zero flashover of some spare parts), and vibration resistance, is the ideal product for using on land and at ship. The MCCB can be installed vertically (vertical mounting) and horizontally (horizontal mounting).Main technical parametersModelframe level rated current (A)Current Rating (A)Rated operation voltage (V)Rated insulation voltage (V)Rated ultimate short circuit breaking capacity (kA) 400VRated operation short circuit breaking capacity (kA) 400VWCM1-63L63(6), 10, 16, 20, 25, 32, 40, 50, 63 AC400AC5002518WCM1-63M5035WCM1-125C100(10), 16, 20, 25, 32, 40, 50, 63, 80, 100AC690AC8002010WCM1-125L3517.5WCM1-125M5035WCM1-125H8550WCM1-250L225100, 125, 140, 160, 180, 200, 225AC690AC8003518WCM1-250M5035WCM1-250H8550WCM1-400L400225, 250, 315, 350, 400AC690AC8005025WCM1-400M6542WCM1-400H10065WCM1-630L630400, 500, 630AC690AC8005025WCM1-630M6542WCM1-630H10065WCM1-800M800630, 700, 800AC690AC8007550WCM1-800H10065WCM1-12508001000, 1250AC690AC8006540WCM1-200012501400, 1600, 1800, 2000AC690AC8006540Attached catalogue
