Description:
-Application:
SMC4 Connector Systems used to connect Renogy Solar Panels consist of male and female SMC4 connectors and branch connectors. This type of connector system is easy to install and uses “snap-in” safety locking tabs to lock two mating connectors, thereby avoiding unintentional disconnection. Also, the mating contacts are sealed against ingress of dust and water.

FAQ:
What is a circuit breaker?
Generally speaking, a circuit breaker is a type of switch that protects us from dangerous electrical situations by automatically turning off the flow of electricity when an overload or other fault occurs.
What's The Miniature Circuit Breaker Working Principle?
There are two arrangement of operation of miniature circuit breaker. One due to thermal effect of over current and other due to electromagnetic effect of over current. The thermal operation of miniature circuit breaker is achieved with a bimetallic strip whenever continuous over current flows through MCB, the bimetallic strip is heated and deflects by bending. This deflection of bimetallic strip releases mechanical latch. As this mechanical latch is attached with operating mechanism, it causes to open the miniature circuit breaker contacts. But during short circuit condition, sudden rising of electric current, causes electromechanical displacement of plunger associated with tripping coil or solenoid of MCB. The plunger strikes the trip lever causing immediate release of latch mechanism consequently open the circuit breaker contacts. This was a simple explanation of miniature circuit breaker
