Mission Critical Circuit Breakers

Selective Coordination

Designed for selectively coordinated systems, mission critical circuit breakers maximize continuity of the electrical

service by allowing the branch circuit breaker to clear the fault.

Mission critical circuit breakers are engineered with technology that optimizes current, time and energy selectivity

so the fault is cleared by the circuit breaker immediately upstream of the occurrence. This technology (see figure

below) allows the remaining areas of the electrical system to continue operation without disruption. In addition to

unique design attributes, Square D mission critical circuit breakers have also undergone rigorous testing

procedures to certify the coordination with downstream circuit breakers—combining innovative engineering with

validated test results.

Apply Square D mission critical circuit breakers in emergency power distribution systems, data centers, hospitals

or anywhere continuity of service is desired.

The PowerPact™ J- and L-Frame Mission Critical circuit breakers deliver high levels of selective coordination in a flexible design that can be easily

configured for a variety of applications. Tested to be selectively coordinated with the QO™ family of miniature circuit breakers and the ED, EG, and EJ

circuit breakers, this solution provides peace of mind when power availability is critical.

An electronic trip unit provides adjustable long-time settings in four sensor sizes, allowing coverage from 70 A through 600 A on a 120–240, 208Y/120,

240, 480Y/277, and 480 V systems.
