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.
• Standards – IEC 60947-2 - UL 489 (Underwriters Laboratories Incorporated)
• Directives – EC directive: “Low Voltage Directives” (LVD) no. 2006/95/CE (in replacement of 73/23/CEE and subsequent amendments); – EC directive: “Electromagnetic Compatibility Directive” (EMC) no. 89/336 EEC.
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
• 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.

Rated service voltage, Ue Rated uninterrupted current
6600 ft A1 A2 [V] 240 240 % 100 100
8500 ft A1 A2 228 228 99 99
13000 ft A1 A2 192 192 96 96

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.
• Circuit breaker weights
Weights Circuit breaker 1 pole Circuit breaker 2 poles Circuit breaker 3 poles
A1 [Lbs] 0.54 1.04 1.54
A2 [Lbs] 0.82 1.61 2.43
• 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).

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.
• Positive operation
• Isolation behavior
• 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;
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 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.
