FAQs

The MPSC323HEAXX2C is designed for fixed horizontal mounting in a standard Magnum frame, enabling straightforward retrofit into existing switchgear without additional hardware changes. The three-pole configuration provides uniform phase protection, ensuring alignment with existing bus bars and mounting features. This simplifies installation, reduces downtime, and supports reliable fault isolation in control panels and machine centers.
This breaker carries UL Listed, CSA Certified, CE Marked, and additional certifications such as KEMA and Lloyd's Register, ANSI, ABS, and DNV GL. These certifications validate regulatory compliance across North American and international installations, reduce procurement risk for multi-site projects, and enable deployment in industries like automotive, water treatment, and food processing where standards and audits are critical.
The PXR20 LSIG trip unit provides adjustable protection with precise short-circuit and long-time settings, enhancing selectivity and faster fault clearance. In both ANSI and IEC contexts, this reduces nuisance trips and protects critical loads. Its compatibility with Eaton’s Power Xpert Protection Manager enables remote monitoring and streamlined protection management for multi-device installations.
This breaker is rated for 3200 A with a 100 kA short-circuit withstand, making it suitable for motor control centers and medium-sized switchgear in manufacturing, process automation, and utility rooms. It excels in environments requiring robust interruption capacity and reliable protection for motors, drives, and feeders under high fault currents.
Upgrading can lower total cost of ownership through reduced downtime, easier maintenance, and standardized protection across sites. The 3200 A rating and LSIG trip units improve reliability, while Power Xpert compatibility shortens commissioning and enables proactive protection management. Consider retrofit fit, spare parts availability, and training time to estimate ROI over the equipment lifecycle.
