    PowerPact Circuit Breakers Product Overview

    PowerPact® J-frame Moulded Case Circuit Breakers give you the right combination of features and performance to satisfy circuit breaker requirements. They deliver unmatched design flexibility across the entire range of 70A to 250A frame sizes offering the benefits of a flexible, modular circuit breaker that panel builders demand.

    Available trip units:
    • Thermal magnetic: Circuit protection provided by individual thermal (overload) and magnetic (short circuit) sensing elements in each pole.
    • Standard electronic: Adjustable overcurrent protection including long-time, instantaneous, and optional short-time.
    • Ammeter: Adjustable long-time, short-time, instantaneous and optional ground fault protection is coupled with integrated current metering and maintenance indicators.
    • Energy: Power and energy metering is integrated with exceptional long-time, short time, instantaneous, and optional ground fault protections. Beyond energy metering, this trip unit delivers many advanced functions including power quality (harmonics) measurement.
    • Thermal Magnetic Circuit Breakers are available from 150 to 250A at up to 600 Vac and 250 Vdc
    • Electronic Trip Circuit Breakers are Available from 70 to 250A at up to 600 Vac
    • Interrupting ratings (AIR) include D-14 kA, G-18 kA, J-25 kA, L-50 kA and R-100 kA at 600 Vac and 20 kA at 250 Vdc.
