Allen-Bradley 1492-GS1G100 Circuit Breaker

The Allen-Bradley 1492-GS1G100 High Density Supplemental Circuit Breaker is a compact, toggle-type protective device engineered for DIN-rail mounting in industrial control panels. This 1-pole miniature circuit breaker is rated at 10 A and supports 277 V AC and 65 V DC, making it suitable for protecting small control circuits, signaling lines, and auxiliary equipment in automation environments. The GS1G100 variant is part of the high-density 1492-GS family, offering reliable overcurrent protection in a space-saving form factor. The housing is glass-filled polyamide 6.6, designed for rugged industrial use, and it employs tubular screw terminals with a self-lifting box lug for secure wire termination on conductors from 22 AWG to 10 AWG. Typical applications include DIN-rail mounted protection within control panels, PLC enclosures, and compact automation cabinets where space optimization is key. Manufactured by Allen-Bradley (Rockwell Automation), this part integrates with the broader 1492-GS line and its accessories, ensuring compatibility with common panel-mounted protection schemes in automation installations.
