Moulded Case Circuit Breaker, MCCB

Moulded Case Circuit Breaker, MCCB Standards GB14048.2Low Voltage Circuit Breaker IEC60947-2 Low Voltage Circuit Breaker Working Condition 1. Altitude <=2000m 2. Ambient temperature: -5'C +40'C (+45'C for marine products) 3. 3 class pollution 4. Inclination <=22.5 degree 5. Work reliably with normal vibration of ships or no more than 4g earthquake 6. No explosion, no gas or conductive dust that would erode the metal or damage the insulation 7. Keep away from rain and snow Features and Benefits 1. High interrupt ratings for the expanding available short circuit currents associated with networked transformers. 2. Overload, short circuit, under voltage protection and isolation function 3. Thermal magnetic and electronic trip for broad applications 4. Large range of rating plug sizes to provide design flexibility 5. Compact size for easy integration into switchboard and power panels 6. Short flashover (some models have no flashover), vibration proof. 7. Endurable in moist air, salt or oil fog and mold environment 8. Either vertical or horizontal installation, complete set of field installable accessories 9.
