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)
((1)
rated current of the current sensors (the PR521 device and the current sensors are available on request)
(2)
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
(3)
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
(4) HD4/UniAir for Unit P1/F (unit with plug-in circuit-breaker)
HD4/UniAir-2R for Unit P1E/2R (unit with plug-in circuit-breaker on the supply and load sides)
(5)
HD4/UniAir-A for Unit P1/A (unit with fixed "upside-down" circuit-breaker)
(6)
HD4/UniAir-F for P1/F Unit (unit with fixed circuit-breaker without wheels and cabled to terminal box); the 12-17.5-24 kV types available are 630 A, 12.5 and 16 kA only
(7)
at 12 and 17.5 kV and at 630 A rated current, the rated short-time withstand current is 20 kA for 1 second
