Characteristics and features of CCB5 DC circuit breaker
Description of instantaneous trip types
C Type
Protect inductive loads and high sensitivity lighting systems
Rated current: 1-63A (at 30 ℃)
Release characteristics: instantaneous release range (7-14) In
K-type
Suitable for providing reliable protection for line equipment in fields such as electric motor systems and transformer distribution systems. The 1.3-fold thermal trip action current of its K-characteristic can effectively protect the motor circuit equipment, while the 14-20-fold magnetic trip action range can be conveniently applied to photovoltaic applications with high resistance to impact current.
The CCB5 series DC circuit breaker can achieve polarity free wiring, ensuring reliable equipment safety.
