    PowerPact B: A Green Premium Product

    This ecolabel guarantees compliance with the most up-to-date environmental regulations.

    Green Premium is the only label that allows you to effectively develop and promote an environmental policy while preserving your business efficiency. More than 75% of Schneider Electric manufactured products, including PowerPact B, have been awarded the Green Premium ecolabel.

  • EverLink Patented Technology

    PowerPact B-frame devices feature EverLink lugs, a new cable connection method with wire creep-compensating technology built directly into the lug. This standard lug option minimizes loose wiring caused by wire strand deformation, vibration, and shocks.
    The patented design maintains low-resistance connections for continuity of service, even with fine stranded conductors.

    • Reduce the loosening of cables over time using a spring tension design
    • Rated for bare use with fine-stranded conductors up to Class K
    • Available with unique integrated control wire terminals

Easy Unit Mount Construction for Flexibility and Versatility

PowerPact B doesn’t require DIN rail brackets, and can be mounted easily on a grid, on a DIN rail, or directly to a backpan. Unit mount construction features integrated DIN rail mounting, and traditional back pan mounting with screws, offering flexibility for the panel builder.

A hinged front cover allows a wide variety of field-installable accessories such as external operators with NEMA and IEC style rotary mechanisms, door shaft operators, and auxiliary contacts.

PowerPact B for I-Line Panelboards

A screwdriver is all you need to install an I-Line PowerPact B circuit breaker, making installation fast and easy. Circuit breakers ratchet firmly onto the bus stack with captive retaining screws to secure the circuit breaker to the mounting pan.

I-Line PowerPact B circuit breakers can be accessorized in the field, and can be installed in new or existing I-Line panelboards. This makes it easy to upgrade legacy panelboards with modern standards and features.


  • PowerPact B I-Line Accessories Flexible, for quick installation and easy retrofits

    • Save up to 40% of time spent mounting and connecting with I-Line plug-on circuit breakers or the unit-mounted circuit breakers with built-in DIN rail mounting
    • Be ready for last minute project changes with one-click, field-installable electrical accessories! Pre-wired versions available
    • Increase operational efficiency with auxiliary contacts that indicate circuit status for remote monitoring systems
    • Easily retrofit PowerPact B-frame circuit breakers into I-Line panelboards and switchboards with 25% more capacity than legacy F-frame circuit breakers
