FAQs

This four-pole, fixed-horizontal-mount breaker is designed for standard LV panel enclosures. Ensure proper busbar alignment, secure mounting hardware, and appropriate clearance around the device. The PXR20 LSIAM trip unit should be wired according to the Magnum PXr installation guide, andZone selective interlocking wiring can be enabled with compatible interlocks to optimize fault isolation and minimize downtime.
The breaker features a PXR20 LSIAM electronic trip unit and a 100 kA interrupting rating, with a main current rating of 3000 A. It supports adjustable protection settings, fast fault detection, and coordination options. This enables selective coordination across feeders and motors, reducing the scope of outages during faults.
Yes. The MPSC304HEAXX2H carries UL Listed, CE Marked, and CSA Certified approvals, along with additional certifications such as ANSI and KEMA. This combination supports global installation programs and helps satisfy regulatory requirements in both North America and Europe.
Yes. The MPSC304HEAXX2H is compatible with zone selective interlocking and Power Xpert protection workflows, enabling selective coordination to isolate faults quickly without interrupting healthy segments, which reduces downtime and arc exposure in complex switchgear configurations.
Expected ROI comes from reduced unplanned downtime, improved protection accuracy, and simpler maintenance with compatible Power Xpert tools. The 3000 A / 100 kA rating combined with UL/CE/CSA certifications supports compliant, scalable protection for critical loads, leading to lower energy waste and shorter repair windows in manufacturing and data-center environments.
