Overview
The Allen-Bradley 1492-SP1C060 is a single-pole supplementary protector/miniature circuit breaker designed for overcurrent protection in industrial automation systems and electrical equipment. This Type C breaker provides reliable thermal-magnetic tripping with a 6-ampere rating and 10,000-ampere breaking capacity at rated voltage. The 1492-SP series meets UL 1077 and CSA C22.2 No. 235 standards for North American applications.
