CHINT NB310L(3PN) Residual Current Operated Circuit Breaker with over-current protection (Magnetic)

1.1 Function

Personnel and fire protection: Cable and line protection against overload and short-circuits.

1.2 Selection

Rated residual operating current

I∆n ＝30 mA: additional protection in the case of direct contact.

Tripping class

A and AC class

A class tripping is ensured for sinusoidal, alternating residual

currents as well as for pulsed DC residual currents, whether they be quickly or slowly increase.

AC class tripping is ensured for sinusoidal, alternating residual currents, whether they be quickly or slowly increase.

Tripping curve

B curve (3 In-5 In) protection and control of the circuits against  overloads and short-circuits; protection for people and big length cables in TN and IT systems.

C curve (5  In-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
