Molded case circuit breakers

Molded case circuit breakers from Schneider Electric include the Square D Powerpact 150A H-frame and 250A J-frame units. The circuit breakers feature common mounting points and handle locations.

Both frames use many types of actuation, including cable-operated handles, rotary handles and electrical motor operators. Changing terminations from bus bar to lug applications can be done with a unique snap-in design.

Many field installable accessories are available, including auxiliary switches, alarm contacts and shunt trips. Both circuit breakers are equipped with a thermal magnetic trip system that may be field installed. Certifications include UL, IEC, CSA and NOM standards.

The circuit breakers are available either as unit mount breakers or fully integrated into Square D Ready-to-Assemble and Factory-Assembled power distribution equipment.
