The Siemens SENTRON 5SJ6216-7KS is a 2-pole miniature circuit breaker rated 16 A with a C tripping characteristic, designed for 400 V AC residential and infrastructure branch circuits. Its 6 kA breaking capacity is certified to both EN 60898 and IEC 60947-2, covering the majority of domestic and light commercial fault-current scenarios.
Occupies 2 modular width units (36 mm) on a DIN rail, with a body depth of 76 mm and an installation depth of 70 mm behind the panel face. The 90 mm height is standard for the SENTRON 5SJ6 family, so it aligns vertically with adjacent breakers and accessories.
Environmental and service ratings
Rated for ambient storage from -40 °C to +75 °C, with periodic operating exposure up to +55 °C and 95% humidity. Halogen-free and silicon-free construction suits environments sensitive to outgassing — data centers, medical facilities, or clean manufacturing zones. Mechanical service life is 20 000 operating cycles typical.
Termination and installation notes
Equipped with screwless outgoing terminals — push-in or cage-clamp style — which speed wiring and reduce torque verification steps during panel build. Mountable in any position. Degree of pollution 2 and overvoltage category III cover fixed-installation environments.
