FAQs

The MPSC324HEAXX2F uses the Magnum standard frame with fixed horizontal mounting, ensuring straightforward retrofit into existing four-pole switchgear and compatible panels. Its four-pole design supports synchronous installation with standard bus bars, while the PXR20 LSIGAM trip unit helps maintain proper coordination with upstream protection devices. This minimizes panel rework and reduces commissioning time during upgrades.
This breaker provides a Rated Uninterruptible current (Iu) of 3200 A and an Interrupt Rating of 100 kAIC. It is a four-pole device in the Magnum PXR family, with a standard frame and fixed horizontal mounting. These specs enable reliable protection for high-demand feeders and motors while supporting fast fault clearance and safe energy dissipation.
Yes. With a 3200 A Iu and 100 kAIC interrupt rating, the MPSC324HEAXX2F is well-suited for data centers, manufacturing lines, and heavy industry where large fault currents and strict protection coordination are common. Its PXR20 LSIGAM trip unit supports selective tripping, reducing unnecessary outages and improving panel uptime in active environments.
The unit carries CE Marked and UL Listed certifications, is NEMA compliant, and aligns with ANSI and Lloyd’s Register certification scopes. Additional marks such as CCC and other regional approvals support deployment in international installations, simplifying regulatory clearance and customer acceptance across sites.
Long-term value comes from reduced downtime due to fast fault clearance, improved coordination with upstream devices, and compatibility with Power Xpert Protection Manager. The unit’s standard frame and mounting ease retrofit, while broad certifications minimize site approval effort. Together, these factors contribute to lower lifecycle costs and faster project delivery.
