FAQs
Plan for proper panel alignment and clearance, verify the panel is rated for surge protection devices, and route conductors per Eaton installation guidelines. Mount the unit within reach of the main power distribution and ensure the NEMA 4X enclosure is suitable for the environment. Connect line and load terminals per the catalog sheet and verify the internal circuit breaker is accessible for maintenance.
A 300 kA per phase rating indicates the device can absorb very large surge events without failing, protecting downstream equipment like drives, PLCs, and sensors. This rating is crucial in facilities prone to lightning strikes, electrical storms, or heavy motor startup transients, delivering higher reliability and reduced risk of uncontrolled outages.
Yes. The SPM300240S3V uses a NEMA 4X enclosure designed for indoor and outdoor installations and challenging environments. The enclosure provides weather resistance and corrosion protection, enabling reliable operation in plant yards, outdoor panels, and retrofit sites where environmental exposure is a concern.
The unit is UL 1449 and UL 1283 listed, CSA recognized, and RoHS compliant. These certifications support meeting electrical safety standards, industry procurement requirements, and environmental regulations, aiding in cross-site deployments and supplier validations.
The surge counter provides visibility into event frequency, enabling targeted preventive maintenance. The 15-year warranty (20 years with registration) reduces lifecycle risk and replacement costs, while high energy absorption minimizes downtime and equipment damage, delivering favorable total cost of ownership for critical loads in data centers, manufacturing lines, and automation cabinets.
