Hydraulic/Magnetic Circuit Breaker
C-Series
The C-Series hydraulic/magnetic circuit breakers are designed for those applications requiring higher amperage and voltage handling capability in a smaller package. Available with American Standard or Metric Threaded Stud terminals, or Saddle Clamp screw terminals. Optional mid-trip handle style actuator allows visual indication of electrical overload with or without alarm feature. These circuit breakers are also available with new solid color rocker actuators and unique two-color Visi-rockerŪ actuators. Visi-rocker can be specified to indicate either the ON or TRIPPED/OFF mode. The exclusive Rockerguard and Push-To-Reset bezel help prevent inadvertent actuation.
The C-Series UL489 circuit breakers employ a unique arc chute design which results in obtaining higher interrupting capacities, up to 10,000 amps. New thermoset glass filled polyester half shell construction provides for increased mechanical and electrical strength. Wiping contacts, mechanical linkage with two step actuation, cleans contacts providing high, positive contact pressure and longer contact life.
C-Series circuit breakers are offered in 1-6 poles, 0.02-100amps, up to 480VAC or 80VDC, UL489 up to 240VAC or 125VDC, with choice of time delays, terminal options, actuator styles and colors.
