The Siemens SENTRON 5SL4416-8 is a 4-pole miniature circuit breaker (MCB) from the 5SL series, rated 16 A with a D tripping characteristic. That 10 kA rating holds under both IEC 60898 and IEC 60947-2, so it's accepted in commercial and light industrial panels, not just residential boards.
Snaps onto standard DIN rail. Occupies 4 modular width units (72 mm wide), with a depth of 76 mm and an installation depth of 70 mm. Mounting position is unrestricted — horizontal, vertical, or upside-down, no derating needed for orientation. Touch protection is built in (finger-safe terminals).
Environmental and service life
Rated for ambient temperatures from -40 °C to +75 °C, with a humidity limit of 95% at +55 °C. The unit is sealable (provision for a lead seal or tamper-evident tag), which is useful for metering or landlord-tenant subpanels where unauthorized switching must be prevented.
