Allen-Bradley 1492-GH010 Circuit Breaker

The Allen-Bradley 1492-GH010 is a 1-amp, 1-pole supplementary protector—often called a miniature circuit breaker—designed to protect control circuits in industrial panels, PLC I/O modules, and motor-control circuits by interrupting overcurrent events before damage occurs. It belongs to the Bulletin 1492 high-density family, is DIN-rail mounted, and provides thermal-magnetic overcurrent protection rated for 250 VAC at 50/60 Hz, with a maximum DC rating of 65 VDC, enabling reliable protection for mixed AC/DC control circuits. With a compact DIN-rail footprint, the 1492-GH010 safeguards low-amperage control circuits—PLC inputs, I/O lines, and field wiring—in automation panels, while its thermal-magnetic design helps discern between temporary surges and sustained faults, improving system reliability. Also compatible with the broader 1492 family accessories and configurations, it supports straightforward integration into existing control schemes and is commonly used in both legacy and modern industrial automation installations.
