The CA3-B0-24-620-31A-D is a C-Series hydraulic-magnetic circuit breaker rated for 20 amps, engineered for applications requiring higher amperage and voltage handling capability in a compact package. This breaker features a unique arc chute design enabling interrupting capacities up to 10,000 amps, with thermoset glass-filled polyester half-shell construction providing increased mechanical and electrical strength. The device incorporates wiping contacts with mechanical linkage and two-step actuation, delivering high positive contact pressure and extended contact life. It is available with multiple terminal options including American Standard or Metric Threaded Stud terminals, or Saddle Clamp screw terminals, and supports optional mid-trip handle actuators for visual indication of electrical overload. The CA3-B0-24-620-31A-D is ideal for industrial control systems, motor protection, and distribution panels where reliable overcurrent protection and compact form factor are essential.
