Carling Technologies' C-Series hydraulic-magnetic circuit breakers provide a robust solution for applications demanding high amperage and voltage capabilities within a smaller footprint. Available in configurations from 1 to 6 poles and amperage ratings from 0.02 to 100 amps, these breakers are UL Recognized up to 480VAC and UL489 Listed up to 240VAC or 125VDC. Key features include a unique arc chute design for high interrupting capacities (up to 10,000 amps), a new thermoset glass-filled polyester half-shell construction for enhanced mechanical and electrical strength, and options for terminal styles and actuator types. Ideal for marine, telecom/datacom, military, renewable energy, and generator/welder applications.
Environmental: Withstands 100 Gs, 6ms sawtooth while carrying rated current; Withstands 0.060” excursion from 10-55 Hz & 10 Gs 55-500 Hz; Method 106D, i.e., ten 24-hour cycles @ +25°C to +65°C, 80-98% RH; Method 101, Condition A (90-95% RH @ 5% NaCl Solution, 96 hrs); Method 107D, Condition A (five cycles @ -55°C to +25°C to +85°C to +25°C)
Maximum Voltage: AC, 480 WYE/277 VAC, 50/60 Hz (see Table A.); UL489: AC,240 VAC. (See Table D), 50/60 Hz, 125 VDC
Current Rating: Standard current coils: 0.100, 0.250, 0.500, 0.750, 1.00, 2.50, 5.00, 7.50, 10.0, 15.0, 25.0, 30.0, 35.0, 40.0, 50.0, 60.0, 70.0, 80.0, 90.0 and 100 amps. Other ratings available
Insulation Resistance: Minimum of 100 Megohms at 500 VDC
Dielectric Strength: UL, CSA: 1960 V 50/60 Hz for one minute between all electrically isolated terminals
Resistance Impedance: Values from Line to Load Terminal - based on Series Trip Circuit Breaker
Endurance: 10,000 ON-OFF operations @ 6 per minute; with rated current & voltage
Trip Free: All C-Series circuit breakers will trip on overload, even when actuator is forcibly held in the ON position
Trip Indication: The operating actuator moves positively to the OFF position when an overload causes the breaker to trip. With mid-trip, handle moves to the mid position on electrical trip of the circuit breaker.
Number of Poles: 1-6 poles ≤ 50A; 1-4 poles @ 51-70A; 1-2 poles 71-100A
Internal Circuit Configuration: Series (with or without auxiliary switch, mid trip & mid trip with alarm switch) Shunt & Relay with current or voltage trip coils, Dual Coil, Switch Only (with or without aux. switch)
