NRC Series
Circuit Breakers
NRC S eries
NRC series circuit breakers offer circuit protection which is far superior to using fuses in
applications containing relay circuits, motor circuits, heater circuits, transformers, solenoid
valves, and semiconductors.
Key features of the NRC series include:
Mounting options include DIN rail, direct surface, or panel cut-out
Rated interrupting capacity of 2,500A (1-pole) and 1,500A (2-pole)
Choice of slide or lever actuators
All models equipped with reset trip indicators
Four curves available for standard or very short delay
Available in 11 rated currents from 300mA to 30A
UL1077 recognized Supplementary Protectors
CSA Certi ed
