FAQs

The MPSC323MEAXXSW uses a drawout vertical mounting with motorized racking for safe extraction and reinsertion. It is built around a standard frame and three-pole configuration, enabling straightforward integration into existing switchgear assemblies. Since it ships without a trip unit, it supports PXR trip units for customized protection and selective coordination in new or retrofit installations.
This breaker is rated for 3200 A with a 100 kA interrupting capacity, suitable for large motor and feeder protection. It is a three-pole device designed for rugged industrial applications. The unit’s drawout design facilitates safe maintenance, and its compatibility with PXR trip units allows precise protection settings aligned with system coordination requirements.
Yes. The combination of a high current rating, substantial interrupting capacity, and motorized racking makes it ideal for data centers, large manufacturing lines, and critical power distribution. Its ability to integrate with PXR trip units supports selective coordination, ensuring preferential protection paths and minimized service impact during faults.
The MPSC323MEAXXSW carries UL Listed status and CE Marking, with ANSI/CSA certification among others, providing robust regulatory compliance for global deployments. This certification mix supports procurement and installation across regulated markets and helps ensure reliability and safety in mission-critical environments.
Motorized racking reduces maintenance time and exposure to energized components by enabling quicker rack/unrack cycles. This lowers labor costs, minimizes downtime during inspections or replacements, and improves overall equipment availability. When paired with protective management software, the solution also simplifies commissioning and ongoing coordination audits, delivering measurable return on investment.
