Product Description
Chint NB1-63 Nb1-63h CCC CE CB UL Semko VDE MCB 1A 2A 3A 4A 6A 10A 16A 20A 25A 32A 40A 50A 63A 1p 2p 3p 4p 6ka 10ka Chnt Mini Miniature Circuit Breaker 
1. General
1.1 Function 
protection of circuits against short-circuit currents, protection of circuits against overload currents, switch,isolation.
NB1 circuit-breakers are used in domestic installation, as well as in commercial and industry electrical distribution systems.

1.2 Selection
Technical data of the network at the point considered: short-circuit current at the circuit-breaker installation point, which must always be less than the breaking capacity of this device, etwork 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.

D curve(10-14In)
protection for circuits which supply loads with high inrush
current at the circuit closing (LV/LV transformers, breakdown lamps).
