NXBL-40Y Residual Current Operated Circuit Breaker

1.1 Function
Personnel and fire protection: Cable and line protection against
overload and short-circuits.
1.2 Selection
Rated residual operating current
IΔn ≤30 mA: additional protection in the case of direct
contact.
IΔn ≤300 mA: preventative fire protection in the case of
ground fault currents.
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.
Tripping curve
B curve (3-5 In) protection and control of the circuits against
overloads and short-circuits; protection for
people and big length cables in TN and IT systems.
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.
1.3 Approvals and certificates
