NB3LE-B\C\D Residual Current Operated Circuit Breaker with Over-current Protection (Electronic)
Rated residual operating current I△n=30mA;
additional protection in the case of direct contact.
Tripping class
AC class-Tripping is ensured for sinusoidal, alternating 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. General
1.1 Approvals and certificates
Detailed information, please refer to Certificates Table on the last page.
2.3 Temperature derating
The maximum permissible current in a circuit breaker depends on the ambient temperature where the circuit breaker is placed. Ambient temperature is the temperature inside the enclosure or switchboard in which the circuit breakers are installed.
The reference temperature is 30℃
