FORMULA. Simplicity and Quality in a Single Product.FORMULA is the cumulation of ABB SACE’s long history of developing effective circuit breakers. It was developed to be simple, but amazes with its extreme quality and versatility.

The highlights of the new line 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 applications

Accompanying accessory line

Reduced circuit breaker depths

The new FORMULA family consists of two frames, A1 and A2, which reach

up to 100A and 250A respectively. Both 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 precise. A reduced number of sales codes simplifies selection and

makes ordering easier. Installation is easy and the circuit breaker is ready for

use immediately.

FORMULA. The Easy and Precise Choice.

How simple and functional can a range of molded case circuit breakers be? By asking this elementary question, ABB conceived the idea for a new family of circuit breakers. The result is FORMULA, the perfect synthesis between ABB SACE’s recognized quality, reliability and simplicity. Simple, with regard to installation, sizing and fitting of accessories.

Reducing dimensions without compromising on performance and reliability is an ABB SACE trademark that helps with installation and increases the work space inside switchboards and panels. FORMULA’s compact design is a great advantage, especially for OEMs, panel builders and installers.

IV - UL FORMULA Molded Case Circuit Breakers

FORMULA. Quality in All Applications.

Quality is great versatility. In addition to the availability of both frames in the three-pole version, for the first time ABB SACE now possesses single-pole and two-pole versions up to 250A, opening the door to the most varied application fields.

Quality is compact overall dimensions. The FORMULA A1 and A2 depth of under 2.5” is the lowest on the market up to 250A.

Construction characteristics

General information

All the molded case circuit breakers in the FORMULA family are constructed in accordance with the follow-

ing construction characteristics:

Double insulation

Positive operation

Isolation behavior

Double insulation Electromagnetic compatibility

Topicalization

Reverse feedable power supply

Versatility of the installation. It is possible to mount the circuit breaker either in the horizontal, vertical, or

lying down position without undergoing any derating of the rated characteristics;

No nominal performance derating for use up to an altitude of 6562 ft. Above 6562 ft, the properties of

the atmosphere (composition of the air, dielectric strength, cooling power and pressure) change, having

an impact on the main parameters which define the circuit breaker. The table below gives the changes to

the main performance parameters.

FORMULA circuit breakers can be used in ambient with a temperature between -25°C to 70°C

(-13°F to 158°F) and stored in a room with atmospheric temperature between -40°C to 70°C

(-40°F to 158°F).

Test pushbutton All FORMULA circuit breakers are fitted with a Test pushbutton which allows the release test to be done. This test must be carried out with the circuit breaker closed.
