Description
The SACE FORMULA circuit-breakers from 15A to 630A consist of the interruption part together
with the trip unit and they can be installed:
? directly on the back plate of the cubicles;
? on a DIN rail (A1 and A2);
? back door (A1, A2 and A3, 2-3 4 poles).
They are characterised by:
? fixed version;
? polarity: 1 pole (A1 and A2), 2 poles (A1 and A2), 3 poles (A1, A2 and A3), 4 poles (A1, A2
and A3);
? maximum breaking capacity of 36kA for A1 and A2 and of 50kA for A3 at 415V AC;
? fixed thermomagnetic trip unit (TMF) for protection of networks in alternating and direct
current (A1, A2, A3);
? ELT LI electronic trip unit with fixed thresholds for the protection of networks in alternating
current (A3);
? only two depths: 60mm (A1, A2) and 103.5mm (A3);
? standard front terminals;
? the possibility of use at 50?C without derating up to 250A (except for A1 125A);
? a special version for A3 300A-400A for use at 50?C.
