The circuit breakers produced by square D are many and varied. The miniature circuit breakers protect electrical circuits from over-current by thermal and magnetic trip. They are small and protect at low amperage, between 10 and 150A.

Two products for this category are the QO(B) circuit breakers and the Multi 9 System UL 489 Miniature circuit breakers. The QO(B) features exclusive Visi-Trip Indicator to provide clear and instant identification of a tripped breaker.

The Multi 9 system carries UL 489 rating for branch circuit protection in amperage under 10A. It is also marked with CE, UL 489, and IEC 947-2. The molded square D breakers are 11, including Mission Critical circuit breakers, ...
... LE/LX molded case electronic breakers, and PowerPact D-Frame molded case breakers.

The PowerPact H-framed molded case breakers handle ratings from 15 to 150A. The PowerPact GJL molded case handle ratings from 15 to100A. The PowerPact P-frame molded case breakers handle ratings from 300 to 800A.

For 240 to 3000A ratings, the PowerPact R-frame molded is ideal. The Masterpact Universal Power circuit breakers are the industry's leading line of medium to large sizes of breakers that feature the Masterpact NT/NW series.

To this category belong 5 different products. These are the Multi 9 C60H-DC, the 500 Vdc Thermal magnetic, Masterpact DC, and Dual rated AC/DC. The dual rates have both dc and ac ratings for application of either system.

The Masterpact dc is an insulated case circuit breaker designed for dc voltage system only. The 500 Vdc thermal-magnetic breakers serve as protection for underground systems of up to 500 Vdc nominal from 30A-2500A.

The Multi 9 C60H is designed per UL 1077 for protection against over current incidences within appliances or electrical equipment. Besides the circuit breakers, square D also provides supplementary protectors, motor circuit protectors, and ground-fault protection products.

In choosing electrical supplies, it is important to consider the reputation of the manufacturer. Having solid experience in delivering excellent products and services are one factor. Square d breakers are designed by experts of remarkable training, experience and knowledge.

Many industries are using square d breakers because of their reliability and performance. What the manufacturer promises, it delivers. Residential houses, schools, corporate and IT towers, as well as power plants rely on square D.
