Key Features of Miniature Circuit Breaker

• are compact in size
• Covering entire range of B Type [L Series], C Type [G Series] and "DC" Series, from 0.5 to 100 Amps and isolators upto 63 Amps.
• Life expectancy are tested for 1,0,000 mechanical operations and 25,000electrical operations thereby making the MCB a life service device
• Available in single and multiple versions with or without neutral breaking.
• Especially suitable for installations with a heavy short- circuit and in load up to 10 KA. Under short- circuit conditions high values of over current occur.
• Under these circumstances a plunger in the solenoid moves with sufficient force to physically separate the contacts.
• Thermal Release: Small overloads are detected by a finally calibrated bimetal element. If the current is greater than the rated current of MCB, the deflection bimetal will be sufficient to trip the MCB.
• Magnetic Release: When a over current of between 3 to 5 times rated current for B Type[L Series] and 5 to 10 times rated current of C types[ G series] MCB changes from thermal to magnetic. The MCB will trip in less than 100 m sec. This is the reason of instaneous tripping.
