NL1 Residual Current Operated Circuit Breaker

Detailed Product Description

NL1 Residual Current Operated Circuit Breaker

Product Features:

1.1 Protection against risk of fire
1.2 Protection against risk of electric shock
1.3 3 protection class: AC, A,
1.4 Tripping class
AC class Tripping is ensured for sinusoidal, alternating currents, whether they be quickly
applied or slowly increase.
A class Tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed
DC residual currents, whether they be quickly applied or slowly increase.
class- can be used as upstream group switch for selective tripping contrary to a
downstream standard RCCB
1.5 Rated residual operating current
30mA- to give a high degree of protection against electric shock in a situation where
supplementary protection against shock from accidental direct contact is required when it
must be able to trip within 40 milliseconds when a fault current of 150mA is detected.
100mA- to give a degree of protection against electric shock due to indirect contact situation.
300mA- to gives overall protection against risk of fire form electrical faults in wiring etc, only
where sufficient current (typically less than 500mA) may cause incandescence of metal parts
in suitable circumstances and in consideration that installed over current devices would
require far in excess of 300mA to operate.
1.6 Fault current indicator
