) "IEC" or "CEI 0-16" version. If the "CEI 0-16" is required, the circuit breaker is always supplied with 3 phase current sensors (Rogowsky coils) installed on the actual circuit breaker and with a
loose toroidal TA. In the "CEI 0-16" version, the REF 601 device opens the circuit breaker by means of the undervoltage release -MU
(
) the rated current of the REF 601 device must be set in the relay in accordance with the circuit breaker's rated current
