Allen-Bradley 1492-GH100B Circuit Breaker

Allen-Bradley 1492-GH100B High-Density Supplemental Circuit Breaker is a 1-pole, 10 A miniature circuit breaker with a push-to-set mechanism for supplemental overcurrent protection in electrical panels and equipment. This thermal-magnetic device supports 250 VAC and 65 VDC ratings and is designed for 50/60 Hz operation, enabling reliable protection for both AC control circuits and DC logic rails in compact DIN-rail installations. The unit’s footprint is a high-density profile: depth about 73.4 mm, height 80 mm, and width roughly 12.4 mm (0.488 in), and it mounts on standard DIN rails to maximize panel space in compact control cabinets. Catalog references frequently list the model as 1492-GH100/B, tying it to Allen-Bradley’s 1492 high-density family of protective devices and indicating its role as a supplementary protector within that family. The 1492-GH series is described as a high-density, thermal-magnetic miniature circuit breaker used for supplemental overcurrent protection in industrial control applications, with certifications including UL, CE, CSA, and CUL, reflecting broad compatibility with North American and international electrical standards.
