Allen-Bradley 1492-SPM2B160 is a 2-pole, 16 A supplementary circuit breaker (Bulletin 1492-SPM) with Trip Curve B and no neutral, designed for 480Y/277 VAC and 96 VDC circuits and delivering up to 10 kA of short‑circuit breaking capacity. It serves as a supplementary protector in industrial control panels and branch circuits, protecting both conductors in the protected path. The 1492-SPM2B160 is intended for resistive or slightly inductive loads and is part of the 1492-SPM family of miniature circuit breakers, commonly used where additional local protection is required alongside a main disconnect.
