SACE FORMULA.
Simplicity and Quality in aSingle Product.

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 ofcircuit-breakers of all polarities, dedicated to the various applications;
- possibility of using the accessories most often requested;
- circuit-breaker depths further reduced;
- a new installation system making assembly of the circuit-breakers easier;
- suitable for use at 50°C without derating.

The new SACE FORMULA family consists of three new A1,
A2 and A3 frames which reach up to 125A,250A and 630A
respectively.
The three frames are available in the fixed version, with front
terminals.
The protection trip unit has fixed thermal and magnetic
threshold values for putting the circuit-breaker into service
more rapidly. This way selection becomes simple and precise.
Whit a few sales codes which simplify selection and make
ordering easier. Installation is simplified, andthanks to easy
and rapid fixing operations and set-up, the circuit-breaker is
ready for use immediately.

SACE FORMULA.
The Easy and Precise Choice.

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 SACEFORMULA, the perfect synthesis between
ABB SACE’s recognized quality, reliability and all-round simplicity:
with regards to installation, sizing and fitting with accessories.
Reducing the dimensions without compromising on
performance and reliability further helps installation, increasing
the work space inside the switchboards. Compactness of
dimensions is a great advantage, especially forOEMs, panel
builders and installers.

SACE FORMULA.
W inners in All Applications.

Quality is great versatility. In addiction to proposing all three
frames in the three-pole and four-pole version, for the first time
ABB SACE now proposes single-pole and two-pole versions up
to 250A, opening the door to the most varied application fields.
Quality is compact overall dimensions. The SACEFORMULA
A1 and A2 depth of just 60 mm is the lowest on the market up
to 250A. Simplicity is this, too.
