YOKG mini circuit breaker PB8N 1P,1P+N, 2P,3P, 3P+N, 4P

Application:

♦ Short-circuit protection

♦ Isolation function

♦ Overload protection

♦ Indication function of contact position

♦ Support 35mm Din-rail installation

♦ Support top incoming and bottom outgoing wiring type, or bottom incoming and top outgoing wiring type

♦ Able to select electrical accessories and achieve distant indication of MCB condition; breaking, closed, and fault tripping

♦ Able to select electrical accessories and realize under-voltage and over-voltage protection of MCB and distant shunt release

Instantaneous tripping characteristic:

Circuit breaker PB8 are designed for protection of distribution and branch circuits, having different load;

 ♦ Curve B----Device should not work in 0.1 second at current 3 In; at current 5 In should work in less than 0.1S

 ♦ Curve C---- Device should not work in 0.1 second at current 5 In; at current 10 In should work in less than 0.1S

 ♦ Curve D---- Device should not work in 0.1 second at current 10 In; at current 20 In should work in less than 0.1S
