FAQs

The MPS8603GEAXXSW is designed for three-pole, drawout vertical mounting with extensions. Begin by confirming enclosure space, align the breaker on the drawout rails, and connect the primary conductors. Ensure the unit is paired with an appropriate Magnum PXR trip unit prior to commissioning. Follow the standard safety procedures and reference Eaton's installation guides for motorized racking and interlock checks to minimize setup time.
This breaker provides 6000 A rated uninterrupted current (Iu) and an 85 kAIC interrupt rating, three-pole configuration, and a double-standard frame. These ratings mean it can sustain high continuous loads without nuisance tripping and interrupt significant fault currents to protect downstream equipment. Use these values to coordinate protection with upstream devices and to ensure adequate fault clearance in demanding motor and feeder applications.
Yes. The unit carries UL Listed, CSA Certified, and CE Marked approvals, along with ANSI ratings, supporting compliance in North America and Europe. It also aligns with related international standards referenced in the product data, which helps streamline procurement for multinational facilities and ensures alignment with local electrical codes and safety requirements.
