 New SACE FORMULA.
Quality For You.

How simple and functional can a range of moulded-case circuit-breakers be? It

was answering this question, which would appear very elementary, that the idea for
a new family of circuit-breakers was conceived at ABB SACE. The result is SACE
FORMULA, the perfect synthesis between ABB SACE’s great quality and reliability
and all-round simplicity: installation, sizing and fitting with accessories.

SACE FORMULA is the expression of all ABB SACE’s long experience of several
decades in all its effectiveness: SACE FORMULA was born basic, but is able to
amaze with its extreme versatility of use.

 The main strong points of the new moulded-case circuit-breakers are:
- just a few but essential versions of the circuit-breakers, easy to select and order;
- availability of circuit-breakers of all polarities, dedicated to the various
different applications;
- possibility of using the accessories most often requested;
- circuit-breaker depths even further reduced;
- a new installation system making assembly of the circuit-breakers easier.
