Chint 25A 2P RCCB Residual Current Protection Enhanced Safety

The CHINT 25A 2-Pole RCCB is designed to provide effective protection against electric shock, earth leakage, and insulation faults in residential and light commercial electrical systems. With a rated current of 40A and two-pole configuration, it disconnects both live and neutral lines when leakage is detected, ensuring comprehensive safety.

RCCB Residual Current Circuit Breaker determine fault currents against earth and protect persons against too high contact voltage in direct and indirect contact. They protect equipment against fire hazard due to insulation faults and are used both in building installation and in industry.

Type A: The tripping takes place at alternating fault current as well as at slowly rising and also at immediate pulsating DC fault current.

Function
Control electric circuits.
Protect people against indirect contacts and additional protection against direct contacts.
Protect installations against fire hazard due to insulation faults.
Personnel and fire protection
Overload protection, short circuit protection, residual current operation
Cable and line protection against overload and short-circuits.
I∆n = 10mA, 30mA: additional protection in the case of direct contact.
C curve (5-10 In) protection and control of the circuits against overloads and short-circuits; protection for resistive and inductive loads with low inrush current.
AC class – Tripping is ensured for sinusoidal, alternating currents, whether they be quickly applied or slowly increase.

Tripping sensitivity:
10mA – precision instrument leakage protection and bathroom use.
30mA – additional protection against direct contact.
100mA – co-ordinated with the earth system according to the formula IΔn ＜50/R, to provide protection against indirect contacts;
300mA/500mA – protection against indirect contacts, as well as fire hazard.
