MCCB circuit breakers
Inquire NowDescription
MCCB circuit breakers are essential components designed for reliable protection in electrical systems. These molded case circuit breakers (MCCBs) are equipped with rated insulation voltage of 800V, making them suitable for AC power systems operating at 50Hz or 60Hz with rated voltages of 690V and below. With a rated current capacity of up to 1250A, these MCCBs are intended for infrequent transfer applications, ensuring the safety and efficiency of electrical power distribution.
Featuring built-in protection devices against overload, short circuits, and undervoltage, these circuit breakers safeguard circuits and power equipment from potential damage. The MCCBs are categorized into four types based on their rated short circuit breaking capacity:
- C type (basic)
- L type (standard)
- M type (high breaking)
- H type (higher breaking)
With a compact design, high breaking capacity, reduced electric arcing, and anti-vibration features, these MCCBs are the ideal choice for both land and maritime applications. They can be installed in either a vertical or horizontal orientation and adhere to international standards including IEC60947-2 and GB14048.2.
