CHINT RCBO/RCCB 25A, 1P+N, 10mA (Water Heater Earth Leakage Protection), NBH8LE / NL1-63-25A

For NL1-63-25A RCCB:
Function:
– Control electric circuits.
– Protect people against indirect contacts and additional protection against direct contacts.
– Protect installations against fire hazard due to insulation faults.
– Residual current circuit breakers are used in housing, tertiary sector and industry.

Selection:
– Detectable wave form

AC class:
Tripping is ensured for slowly increasing sinusoidal AC residual currents.

A class:
Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly.

S, G/SI class:
Tripping is ensured not only for sinusoidal AC residual currents but also for pulsed DC residual currents whether applied suddenly or increasing slowly. S, G/SI type with filters against spurious tripping caused by harmonics and transient surges.

With the impact of 8/20us surge 3000A, this high immunity
RCCB will still be in stable status.

For NBH8LE RCBO:
Function
– Personnel and fire protection
– Cable and line protection against overload and short-circuits.

Selection
– 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.
