Siemens 5SM1 111-6 Circuit Breaker

Siemens 5SM1 111-6 is a 2‑pole residual current circuit breaker (RCCB) from the 5SM1 family, delivering earth‑leakage protection for electrical circuits with a nominal current rating of 16 A. This unit provides tripping on a residual current of 10 mA (Type A operation) to minimize shock risk while protecting equipment from leakage faults, and it is suitable for 230 V AC mains at 50/60 Hz. As a compact RCCB, it interrupts both conductors when leakage is detected, helping prevent electric shock and fire hazards in distribution panels or enclosures. Common applications include protection of lighting and outlet circuits in residential and light commercial installations where fast leakage detection is required.
