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 UL Recognized File No. LR83454 File No. E68029 Speci cations Protection Method Electromagnetic tripping Internal Circuit Series current trip Number of Poles 1, 2 Rated Voltage 250V AC (50/60Hz), 65V DC Rated Tripping Currents 0.3A, 0.5A, 1A, 2A, 3A, 5A, 7A, 10A, 15A, 20A, 30A 2,500A, 250V AC, 50/60Hz Rated Interrupting Capacity (2-pole: 1,500A) SPDT contact output Auxiliary Contact 250V AC 3A (resistive load) 65V DC 1A (resistive load)) Reference Temperature 40C Operating Temperature 10 to +60C (avoid freezing) Insulation Resistance 100M (500V megger) Between the live part and the ground, between terminals of different poles, between terminals Dielectric Strength of the same pole, and between main circuit and auxiliary contact: 2,000V AC, 1 minute 100N (approximately 10G) Vibration Resistance (10 to 55Hz) Shock Resistance 500N (approximately 50G) Life 10,000 operations minimum Main terminal: M4 screw (20A maximum) Terminal Style M5 screw (30A model) Auxiliary terminal: M3.5 screw Weight (approximate) 1-pole: 115g, 2-pole: 230g Not suitable for branch circuit protection. 900 www.idec.com Circuit Breakers Terminal Blocks Timers Relays & Sockets Display Lights Switches & Pilot LightsCircuit Breakers Switches & Pilot Lights Display Lights Relays & Sockets Timers Terminal Blocks NRC Series Circuit Breakers Part Numbering Guide NRC series part numbers are composed of 5 part number codes.
