C-SC-Series eries
HYDRAULIC-MAGNETIC CIRCUIT BREAKER
The C-Series hydraulic-magnetic circuit breakers are ideal for applications that require higher amperage and
voltage handling capability in a smaller package. They are available in 1-6 poles, 0.02-100amps, UL Recognized
up to 480VAC or 150VDC, UL489 Listed up to 240VAC or 125VDC, with choice of time delays, terminal
options, actuator styles and colors. The C-Series employs a unique arc chute design which allows for higher
interrupting capacities of up to 10,000 amps. Thermoset glass filled polyester half shell construction provides
for increased mechanical and electrical strength. The wiping contacts mechanical linkage, with two step
actuation, cleans contacts providing high, positive contact pressure and longer contact life. Available with
American Standard or Metric Threaded Stud terminals, or Saddle Clamp screw terminals. The optional mid-trip
handle style actuator allows a visual indication of electrical overload with or without alarm feature.
