Choosing the right DC circuit breaker
When purchasing a DC MCB , there are three core points: matching the voltage and current of the system, ensuring that protection does not "fail" under extreme operating conditions, and controlling the full...
• ventilation slot The ventilation slot and cooling chamberhave strong
heat dissipation performance.
• red copper terminal block Thickness up to 1.0mm.
• indication window design Signal whether the fused core is fused or
not(light on fused, off on normal)
