High interrupting capacity and a robust current rating translate into safer protection of feeders, motors, and panels in harsh industrial environments. The four-pole design improves protection coordination and fault current handling across three phases plus neutral, reducing the risk of cascading trips. The drawout vertical mounting simplifies insertion and removal during maintenance, enabling faster replacements and lower downtime in production lines. Being shipped without a trip unit provides flexibility to pair with a specific external protection scheme or retrofit with an appropriate release at a later date, supporting long-term asset optimization. Global certifications and compliance—UL Listed, CE Marked, ANSI/CSA—reduce regulatory risk and facilitate cross-border sourcing for multinational projects. The standard frame and defined dimensions help with panel planning and retrofits, while the 3000 A / 100 kA ratings ensure resilience for high-demand power systems. Renewal parts and broad Magnum family compatibility further boost serviceability and lifecycle economics.

FAQs

For installation, plan for a four-pole, drawout vertical mounting in a standard frame panel. Ensure adequate clearance for insertion/removal, proper rail alignment, and clearance around bus bars. Confirm the breaker is compatible with the existing protection scheme and that any required external trip unit or relays are sourced separately to meet your coordination strategy.
The MPSC304WEAXXSW carries UL Listed, CE Marked, ANSI and CSA certifications, among others. These approvals validate safety, performance, and cross-border compliance, reducing regulatory risk for installation in multiple regions and easing procurement for multinational projects while supporting audit readiness.
This model ships without a trip unit, so it does not include an internal release. For customized protection, pair it with a compatible external trip unit or protection relay, or upgrade to a Magnum PXr assembly when a built-in protection module is required, ensuring proper coordination with upstream and downstream devices.
Its four-pole design and 100 kA interrupting capacity suit motor control centers, conveyors, pumps, and process panels in manufacturing, as well as power distribution cabinets in data centers. The drawout feature supports quick maintenance and the high current rating supports large motors and critical loads without compromising safety.
Plan for periodic inspection of the drawout mechanism, ensure compatibility with any required external trip unit, and track renewal parts availability for the Magnum family. With a 3000 A rating and 100 kA capacity, schedule regular fault-current testing and panel checks to minimize downtime and optimize total cost of ownership.
