Allen-Bradley 1492-SPM1D010 Circuit Breaker

Allen-Bradley 1492-SPM1D010 is a 1-pole supplementary circuit breaker from Rockwell Automation’s 1492-SPM family, designed to provide additional protection for individual circuits within 1492-SPM installations. This model is the 1 A, no-neutral variant (catalog number 1492-SPM1D010), featuring Trip Curve D to rapidly interrupt short-circuit faults while tolerating moderate inrush. The neutral-equipped version is 1492-SPM1D010-N. The 1492-SPM series is specified with a short-circuit current rating up to 10 kA, making it suitable for use as a compact, single-pole protection device in control panels and machine circuits that require dedicated protection for each branch. As a supplemental protector, it is designed to integrate with compatible 1492-SPM bus blocks and accessories within Rockwell Automation control architectures.
