Allen-Bradley 1492-SPM1D150 Circuit Breaker

Allen-Bradley 1492-SPM1D150 is a 1-pole supplementary circuit breaker (Bulletin 1492-SPM) with a trip curve D and a 15 A rating, designed for use with Allen-Bradley 1492-SPM modular protection in control panels. The No Neutral variant is identified by the 1492-SPM1D150 designation and does not provide a neutral connection. The 1492-SPM family typically lists voltage ratings of 240 VAC and 62.5 VDC with a 15 kA short-circuit breaking capacity, making it suitable for protecting small loads or PLC I/O circuits in industrial control applications. This miniature breaker is compact for 1-pole configurations in 1492-SPM enclosures and supports selective tripping to guard downstream devices.
