FAQs

Installation begins with confirming panel compatibility for Magnum PXR devices, wiring to the three-pole bus and busbar stabs, and securing the unit in the standard frame with vertical drawout rails. Follow the MN013016en manual for step-by-step isolation, torque specs, and LSIG/trip unit integration. The drawout design speeds replacement and minimizes exposure during servicing.
The PX R release supports LSIG electronic protection, offering long-time and short-time protection with adjustable curves and coordination settings. This enables precise fault discrimination, reduced nuisance trips, and streamlined commissioning. For applications requiring motor protection and feeders, the LSIG option simplifies tuning while maintaining robust protection performance.
Yes. With a three-pole configuration, drawout mounting, and high interrupting capacity (100 kA), the breaker is well-suited for motor control centers and industrial switchgear. Certification coverage (UL Listed, CE Marked, CSA Certified) supports global deployments, while the rugged Magnum platform and PX R compatibility provide reliable protection across demanding environments.
The MPSC303WEAXX2C carries UL Listed, CE Marked, and CSA Certified approvals, plus Lloyd's Register certification. These attest to safety and performance per global standards, simplifying cross-border procurement, equipment acceptance by regulators, and conformity to NEC/NEMA requirements. For multi-region projects, these certifications reduce qualification time and regulatory risk.
Expect reduced downtime due to easier drawout maintenance, faster fault isolation from precise LSIG protection, and improved protection coordination with PX R integration. Remote monitoring and faster protection tuning further lower field service costs, shorten mean time to repair, and deliver a lower total cost of ownership for critical power systems.
