UL FORMULA Molded Case Circuit Breakers - I
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
• panying accessory line
• Reduced circuit breaker depths
II - UL FORMULA Molded Case Circuit Breakers
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 ic threshold values
for putting the circuit breaker into service more rapidly. This way selection
es 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.
UL FORMULA Molded Case Circuit Breakers - III
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 promising on performance and reliability is an ABB SACE trademark that helps with installation
