FAQs

When installing the MPS8404VEAXX2S Magnum breaker, ensure a fixed vertical mounting arrangement within a suitable panel space that supports four-pole operation. Confirm compatibility with standard bus bars and adequate clearance for heat dissipation. Use the correct torque specs for terminal connections and follow the Power Xpert Release trip unit installation guidelines to enable full protection features and remote diagnostics.
Key specs include a four-pole configuration, a 4000 A frame, and an 85 kA interrupting rating. The device is UL Listed and CE marked with NEMA compliance, supporting ANSI and CSA certifications. It uses the PXR25 LSIGAM trip unit for advanced protection, and it is designed for fixed vertical mounting in demanding industrial environments.
Yes. The MPS8404VEAXX2S is designed for high-current motor protection with a four-pole configuration and high interrupting capacity, enabling selective coordination in motor control centers. Its PXR trip unit supports precise protection settings, reducing nuisance trips while safeguarding motors and drives. Its compatibility with Power Xpert Protection Manager aids centralized monitoring and fast fault isolation.
This breaker carries UL Listed, CE Marked, and ANSI/CSA certifications, along with additional approvals like KEMA, Lloyd's Register, ABS, and DNV GL. Such certifications support global deployments, regulatory compliance, and supplier risk reduction. They validate safety, performance, and reliability, enabling procurement teams to meet diverse international standards without component-level substitutions.
Magnum PXR breakers offer durable protection with reduced maintenance through diagnostics-enabled trip units and remote monitoring. The PXR system simplifies protection coordination, lowers downtime, and improves mean time to repair (MTTR) when faults occur. Over time, this translates to lower total cost of ownership, fewer nuisance trips, and better asset longevity in complex automation and power distribution networks.
