NL210 Residual Current Operated Circuit Breaker without over-current protection
General
- protection prople against indirect contacts and additional protection against direct contacts.
- protect installations against fire hazard due to insulation faults.
Detectable wave form
- B Class Tripping is ensure for sinusoidal AC resisdual currents pulsed DC residual currents, alternating residual sinusoidal currents up to 1000Hz, pulsating direct residual current and for smooth direct residual currents, whether applied suddenly or increasing slowly.
Tripping sensitivity
- 30mA-additional protection against direct contact
Tripping time
- Instantaneous it ensures instantaneous tripping (with out time-delay.)
NXL-63
General
- 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.
Tripping sensitivity
10mA – precision instrument leakage protection and bathroom use.
30mA – additional protection against direct contact.
300mA – protection against indirect contacts, as well as fire hazard.
Tripping time Instantaneous
It ensures instantaneous tripping (without time-delay)
