Allen-Bradley 1492-SP1B100N Circuit Breaker Module

The Allen-Bradley 1492-SP1B100N is a 1-pole supplementary circuit breaker with a neutral option (N) designed for Bulletin 1492 SP series protection modules. It provides overcurrent protection for control circuits with a B-type trip curve and is rated at 10 A, using thermal-magnetic principles for reliable protection. The unit supports 277 V AC applications with a short-circuit interruption rating up to 10 kA at 277 V, and it features line- and load-side lug terminals for straightforward wiring; the neutral option enables 1P + N installations in compatible panel assemblies. This module is typically used in industrial automation to protect individual circuit branches within Allen-Bradley 1492-based control and power protection schemes.
