Product Description

                                           Newly  designed  Mini  Circuit  Breaker 
                                                       GKB-63 1P



GKB-63 three-phase unbalanced treatment circuit breaker is suitable for AC 50/60Hz, rated voltage does not exceed 415V, rated
current to 63A circuit overload and short-circuit protection. Each phase of three-phase and four-wire has its own dedicated connection
channel, which is non-interference with each other.

Technial Parameters

Installation and maintenance

• Check whether the circuit breaker mark is consistent with the normal working conditions before installation;
• Before power on, manually operate the circuit breaker for several times, the mechanism action should be flexible, reliable, no blocking
phenomenon;
• Circuit breaker should be checked periodically during operation;
• After breaking the overload or short circuit current, the circuit breaker shall frst remove the fault and then restore the closing;
• Circuit breaker shall not fall or be affected by rain during use, storage and transportation
