increase the indicated weight by 20 kg for circuit-breakers with PR521 / REF 601 devices and 3 current sensors (15 kg only with 2 current sensors)
(4)
rated current of the current sensors (the PR521 device and the current sensors are available on request); at 24 kV, only 2 current sensors for PR521 (installed on the circuit-breaker’s
lateral poles) can be used with 230 mm center-distance between poles
(5)
the REF 601 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
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
(6) at 12 and 17.5 kV and at 630 A rated current, the rated short-time withstand current is 20 kA for 1 second
