Allen-Bradley 1492-SP3C100 Circuit Breaker

Allen-Bradley 1492-SP3C100 is a 3-pole supplementary protector/circuit breaker from Rockwell Automation’s 1492-SP family, rated for 10 A and designed for IEC 415 V AC operation (UL/CSA compatibility for 480Y/277 V AC). It is a DIN-rail mounted, molded‑case device configured without a neutral pole in this variant. The C‑trip magnetic/thermal mechanism provides overcurrent protection tailored to inductive loads, with a magnetic trip range typically 5–10 times the rated current. Terminals are line and load side lug connections, enabling secure wiring in compact control panels. This unit supports protection in 3‑phase circuits and is intended for supplemental protection in industrial automation applications, including control panels, motor control centers, and distribution panels. It carries the Bulletin 1492-SP designation and is part of the broader 1492-SP supplemental‑protection line used when a dedicated protective device is required in 3‑phase systems.
