Product Description

Chint NBH8-40 NBH4-40H MCB 1P+N DPN 1A 2A 3A 4A 6A 10A 16A 20A 25A 32A 40A Chnt Chint NBH8 Mini Circuit Breaker 
 

1.1 Function

protection of circuits against short-circuit currents,protection of circuits against overload currents,switch,isolation.

 

1.2 Selection

- Technical data of the network at the point considered: the earthing systems (TNS, TNC),

- Short circuit current at the circuit-breaker installation point,  which must be less than the breaking capacity of this device,

- Network normal voltage.

- Tripping curves:

B curve (3-5In)  protection for people and big length cables in TN and IT  systems. 

C curve (5-10In) protection for resistive and inductive loads with low inrush current.
