Allen-Bradley 1492-SPM3C060 Three-Phase Circuit Breaker

The Allen-Bradley 1492-SPM3C060 is a three-pole, 6 A miniature circuit breaker from Rockwell Automation’s Series D, engineered to provide overcurrent and short-circuit protection for three‑phase control and power circuits in industrial electrical distribution systems. It is commonly installed in control panels, machinery enclosures, and industrial distribution boards, with a compact DIN rail–mountable design that helps maintain compliance with industrial safety and protection standards and supports neat, scalable panel layouts. This C‑curve device protects three‑phase circuits and is rated for industrial AC systems, with voltage rating and breaking capacity described as application dependent. It serves to protect motors, drives, and control circuits across manufacturing plants, material handling, HVAC equipment, and process automation facilities. Common replacements include Allen-Bradley 1492-SPM3C100, Schneider Electric A9F74306, and Siemens 5SY4306-7.
