SACE FORMULA DSA overview and distinctive
features
Simplicity and quality in a single product

SACE FORMULA DSA range is the outcome of ABB SACE long history providing
effective circuit-breakers. It was developed to be simple but amazing with its
extreme quality and versatility.

The highlights of SACE FORMULA DSA range of

molded case circuit-breakers include:
• Quick and easy selection and ordering with
few, but essential, versions of circuit-breakers
• Multiple polarities, dedicated to various appli-
cations
• Accompanying accessory line
• Reduced circuit-breaker depths
• A new installation system making assembly of
the circuit-breakers easier;
• Suitable for use at 50°C without derating.

The SACE FORMULA DSA family consists of four

frames (A0, A1, A2 and A3) which reach up 630A.
These frames are available in the fixed version,
with front terminals.

The protection trip unit has fixed thermal and

magnetic threshold values to put the cir-
cuit-breaker into service more rapidly. A reduced
number of product codes simplifies selection and
makes ordering easier. Installation is easy and the
circuit-breaker is ready for immediate use.

Thermal-magnetic trip units

The thermal-magnetic trip units TMF, with fixed circuit due to the magnetic device:
thermal and magnetic threshold, are generally • Thermal protection (L): fixed threshold I 1= 1x1In,
used in power distribution plants. with long inverse time trip curve
They allow protection against overloads due to • Magnetic protection (I): fixed threshold
the thermal device and protection against short I 3= 10xIn, with instantaneous trip curve
• Neutral at 100% for 4 -pole circuit-breakers.

For example for overload current 2xI 1 , the trip
