CNKA 100 amp dc circuit breaker Classification

The principle of DC circuit breaker topologies is intricate. Based on the primary breaking devices used, DC circuit breakers can be categorized into three types: mechanical DC circuit breakers, fully solid-state DC circuit breakers, and hybrid DC circuit breakers that integrate both mechanical and solid-state switches. These variations in structure and operational principles enable different DC circuits to achieve dependable circuit protection and switch control.

CNKA 100 amp dc circuit breaker Connection 

There are two primary wiring methods for DC circuit breakers: backplane wiring and plug-in wiring. Backplane wiring offers the advantage that during maintenance, only the front power supply needs to be disconnected without the need for rewiring. However, this method requires careful installation according to manufacturer specifications to avoid impacting the circuit breaker's normal operation.

Plug-in wiring, on the other hand, provides greater convenience. When replacing the circuit breaker, simply unplug the old one and insert the new one. It is crucial to securely fasten the plug during installation to minimize contact resistance and enhance overall safety and reliability.
