FAQs

Install the four-pole, drawout breaker into a suitably rated low-voltage panel designed for 4000 A and 100 kA fault current. Use the vertical drawout mechanism with the motorized racking to engage and withdraw the unit safely, following the manufacturer's interlock procedures. Ensure the Protection Unit (PXR20 LS IAM) is configured for the system and verify control wiring, alignment, and panel clearance to prevent arcing or mis-trips.
The PXR20 LSIAM trip unit provides advanced protection logic with adjustable, state-specific curves and instantaneous trip settings to optimize coordination along the feeder chain. This reduces unnecessary trips on non-fault alarms and limits arc energy exposure. It is particularly beneficial for motor feeders and multi-load buses where precise selectivity minimizes downtime while preserving protection integrity.
Yes. With a 4000 A rating and 100 kA short-circuit capability, four-pole configuration, and motorized racking, it suits high-energy manufacturing lines and data center feeders requiring robust protection and rapid, reliable switching. Its PXR20/LUIs trip unit supports selective coordination across complex power architectures, helping maintain uptime and protect valuable equipment under fault conditions.
The MPSC4A4MEAXX2H carries UL Listed and CE Marked status, along with SABA listing and ANSI, CSA certifications. Additional approvals include Lloyd's Register, KEMA, ABS, and DNV GL, enabling confident deployment in diverse regions and stricter regulatory environments. Always verify local requirements to ensure full conformity for your installation site.
Investing in the Magnum breaker with motorized racking and a PXR20 trip unit reduces maintenance labor through faster drawout operations and safer, simpler maintenance cycles. The enhanced protection coordination lowers unexpected downtime, while widely recognized certifications simplify vendor qualification across sites. Access to technical papers and protection software also supports proactive maintenance and lifecycle planning.
