Overview
The Square D Multi 9 C60SP (M9F23316) is a 3-pole miniature circuit breaker engineered for distribution applications in commercial and industrial control panels. Rated 16A at 480Y/277V AC with a 10kA breaking capacity, it delivers reliable overcurrent and short-circuit protection using thermal-magnetic trip technology with a D-curve characteristic. Designed to the Multi9 multistandard platform, it meets UL 1077, CSA C22.2 No. 235, IEC/EN 60947-2, and GB 14048.2 simultaneously — enabling a single panel design for North American and international markets. Clip-on DIN rail mounting and tunnel-type terminals on both line and load ends make installation fast and flexible.
