FAQs

Yes. The MPSC304MEAXXSW is a four-pole Magnum frame designed for drawout vertical mounting and motorized racking, and it is compatible with Magnum PXR trip units when a protection scheme is specified. Note that the unit ships without a trip unit, so you must select a suitable Power Xpert Release or equivalent trip unit to meet your protection requirements.
This breaker has a 3000 A continuous current rating and a 100 kA short-circuit interruption rating in a four-pole configuration. It is intended for large motor feeders and heavy-duty loads in industrial settings. Proper coordination with upstream devices and correct trip-unit selection are essential to achieve optimal protection across the system.
Yes. The 3000 A / 100 kA-rated Magnum frame supports MCCs and heavy motor loads found in manufacturing plants, including pumps, conveyors, and process equipment. Its drawout mounting and motorized racking simplify maintenance, while its robust protection capacity helps prevent cascading trips and downtime during start-up and fault events.
The MPSC304MEAXXSW carries UL Listed, CSA Certified, CE Marked, and Lloyd's Register certifications, with additional compliance marks such as CCC Marked and NEMA compatibility noted. This broad certification footprint supports global procurement, regulatory approvals, and cross-border installations with reduced compliance risk.
The drawout design with motorized racking enables faster, safer maintenance and easier hot-swaps, reducing downtime during inspections or replacements. The absence of a fixed trip unit at purchase allows staged protection upgrades, lowering initial capital expenditure. Over the life of the installation, you gain improved uptime, easier upgrades, and alignment with evolving protection schemes.
