Question:
With which safety integrity according to IEC 62061 and ISO 13849-1 can a combination of a power contactor and a circuit-breaker (with undervoltage release) be assessed in a safety function?

Answer:
Max. SIL 2 according to IEC 62061 or PL d in accordance with ISO 13849-1 can be achieved in conjunction with a safety-related evaluation, for instance a fail-safe controller or a safety relay.
