Schneider Electric M9F22116 Miniature Circuit Breaker

Schneider Electric M9F22116 Miniature Circuit Breaker is a single-pole MCB from the Multi9 C60SP family, rated for 16 A with a C-type trip curve. It is designed for protective switching in low-voltage distribution panels, interrupting fault currents up to 10 kA in both UL 1077 and IEC/EN 60947-2 environments and is rated for 277 V AC circuits. This thermal-magnetic device protects branch circuits in commercial and light industrial applications such as lighting runs, general power distribution, and control circuits, providing overload protection and short-circuit protection in a compact, molded-case form factor. With a 1P configuration, it supports straightforward integration into standard distribution assemblies and coordinates with other protective devices in typical panel architectures. The M9F22116 carries the standard trip characteristics of the C60SP line, offering reliable, predictable protection for circuits with moderate inrush currents while meeting key global safety standards. Whether replacing a failed breaker or stocking spares for a maintenance program, this Schneider Electric MCB fits common 277 V AC distribution schemes and supports rapid protection updates in retrofit projects or new-build panels.
