(1) increase the indicated weight by 20 kg for circuit-breakers with REF 601 devices and 3 current sensors (15 kg only with 2 current sensors)
the REF601 device and the current sensors are available on request. The rated current of the REF 601 must be set in the relay and must be compatible with the rated current of the
(2)
circuit-breaker. The rated current that can be set with CEI 0-16 is 80 A or 250 A. With the CEI 0-16 version of REF 601, the circuit-breaker is always supplied with 3 phase sensors
(Rogowsky coils) on the circuit-breaker itself, one 40/1 A closed-core toroidal TA and a -MU undervoltage release for relay-controlled opening
at 12 and 17.5 kV and at 630 A rated current, the rated short-time withstand current is 20 kA for 1 second
(3)
(4) at 12, the rated short-time withstand current is 25 kA for 2 seconds
at 17.5 kV, the breaking capacity is 21 kA and the rated short-time withstand current is 21 kA for 3 seconds
