Allen-Bradley 1492-SP1D070 is a one-pole supplementary protector (circuit breaker) rated for 7 A at 277 V AC, part of the 1492 family used for compact protection in control circuits. It is UL/CSA-listed for 277 V AC operation and configured as a single-pole device with a 7 A continuous rating. The 1492-SP1D070 line has been discontinued by the manufacturer, with the recommended replacement being 1492-SPM1D070-N, which preserves the same 7 A rating and adds a magnetically-tripped variant for inductive loads.
