The Siemens 5SL6406-7RC is a SENTRON miniature circuit breaker (MCB) rated 6 A at 415 V AC, 4-pole, with a C tripping characteristic and a breaking capacity of 7.5 kA per EN 60898. The IP20 rating applies only with connected conductors — the busbar stabs and terminals are finger-safe but the breaker itself isn't sealed against dust ingress.
Panel fit & compliance
At 72 mm wide (4 module widths) and 76 mm deep, it drops onto any standard 35 mm DIN rail. The sealable option lets you lock the toggle position to prevent unauthorized reset after a trip.
