NL1 Residual Current Operated Circuit Breaker without Over-current Protection (Magnetic)

Modular DIN Rail-Residual Current Circuit Breaker

1.1 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.

1.2 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 Class type with filters against

spurious tripping caused by harmonics and transient surges.

With the impact of 8/20us surge 300A, this high immunity

RCCB will still be in stable status.
