Product Description

Chint Nb1-63 277V 440V 480V 50Hz 60Hz MCB 1 2 3 4 Pole 1 2 3 4 6 10 16 20 25 32 40 50 63 AMP UL1077 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).
