FAQs

The MPS8404HEAXX2C uses fixed horizontal mounting within a Magnum frame, designed for large distribution panels and switchgear. Expect a substantial footprint (approx. 16.3 in depth, 16.8 in height, 44.1 in width) and a weight around 319 lb, which informs enclosure clearances. For optimal protection, pair with PXR20 LSIG for coordinated tripping and signaling.
This breaker is four-pole with a 4000 A rating and an 85 kA short-circuit withstand rating (Icu). It uses the PXR20 LSIG trip unit, enabling selective coordination and reliable protection for high-amp feeders. The combination supports precise protection schemes in demanding industrial environments and aligns with Power Xpert protection strategies.
Yes. The unit carries UL Listed and CSA Certified marks, plus CE Marked compliance and NEMA alignment. These certifications support global installations, simplify regulatory approvals, and help ensure consistent performance across facilities that mandate recognized safety and performance standards.
PX R trip units provide enhanced protection logic, enabling selective coordination and remote signaling to central protection managers. This reduces nuisance trips, improves fault isolation, and simplifies maintenance planning, delivering measurable uptime gains in continuous manufacturing and critical process applications.
The Magnum MPS8404HEAXX2C combines high fault current capability with robust certifications, supporting long service life in tough environments. Its installation in properly sized enclosures reduces rework, while tight coordination with PXR systems lowers downtime and maintenance costs through improved protection accuracy and easier diagnostics.
