CB2-B0-26-615-121-D is a C-Series hydraulic-magnetic circuit breaker designed for electrical overload and short-circuit protection in compact applications. This 15-amp rated breaker features screw terminal configuration with saddle and washer clamps (10-32 size), and an ON-OFF actuator with white color marking. The breaker employs a unique arc chute design enabling interrupting capacities up to 10,000 amps, with thermoset glass-filled polyester construction for enhanced mechanical and electrical strength. It is UL Recognized up to 480VAC or 150VDC, and UL489 Listed up to 240VAC or 125VDC. The wiping contacts and mechanical linkage with two-step actuation provide high positive contact pressure and extended contact life, making it ideal for industrial control panels, motor protection, and power distribution systems requiring reliable overcurrent protection.
