Built for residential load centers requiring high-density circuit configurations, this 15-amp single-pole component utilizes a slim half-inch form factor. The thermal-magnetic mechanism ensures consistent response to overcurrent events on standard branch wiring. Electricians rely on this classified model to fit Challenger, Crouse-Hinds MH, Murray MP, and Thomas & Betts enclosures. It seamlessly replaces legacy A115 and MH115 units during panel maintenance.
