This is the iC60N Miniatur-Leistungsschalter (MCB) from Schneider Electric Acti9-Serie. It features a 3-pole design, C-curve tripping characteristic, rated current of 16A and standard breaking capacity of 6kA. It is mounted on industry-standard 35mm DIN rail. Primarily applied to three-phase AC power distribution circuits to provide dual protection against circuit overload and short circuit. Widely used for terminal power distribution in residential buildings, commercial premises and light industrial facilities. Featuring strong versatility, it is compatible with mainstream distribution boxes.
