Allen-Bradley 1492-SP2B100 Circuit Breaker

Allen-Bradley 1492-SP2B100 is a two-pole supplementary protector circuit breaker from the 1492-SP family, rated for 10 A on 480 V AC circuits. It is a bulletin 1492 device with a B-type trip curve, delivering both long-time and instantaneous trip actions to guard against overloads and short circuits. The breaker uses a fixed (non-interchangeable) trip unit and provides line- and load-side lug terminals for straightforward wiring; it can be configured for feed-through arrangements in compatible enclosures. With a nominal breaking capacity of 10 kA at 480 V, it is suitable for protecting feeders and branch circuits in industrial equipment, control panels, and power-distribution enclosures where a supplemental protection device is needed alongside a main breaker. The 1492-SP2B100 is a 2-pole, 1-phase device, aligning with typical 480 VAC control systems, and is designed for applications requiring reliable coordination in rugged industrial environments. As a molded-case breaker, it offers a compact, robust form factor suitable for modern control panels and industrial enclosures.
