Quick Summary

Eaton Magnum low voltage power circuit breaker protects electrical systems in industrial facilities. Engineers often face nuisance trips and downtime when protection coordination isn’t precise, so the MPSC324HEAXX2C uses a PXR20 LSIG trip unit to enable selective protection and rapid fault clearance. This unit carries UL Listed, CE Marked, and Lloyd’s Register certifications, with CSA and KEMA certifications supporting global deployment. By pairing a standard frame four-pole Magnum design with 3200 A Iu and 100 kAIC interrupt capability, it integrates easily into existing protection schemes, delivering reliability while simplifying maintenance and sparing project timelines. The result is improved uptime and lower total cost of ownership through proven protection coordination and ready compatibility with Power Xpert and zone-selective strategies.
