Special features
Standard with surge counter
High-energy protection at 300 kA per phase provides robust defense against industrial transients. This capability translates to measurable business impact: fewer unexpected failures in motors, drives, and PLCs, lowering replacement costs and unplanned downtime. In manufacturing and process environments, it supports uptime for CNC machines, conveyors, and variable-frequency drives, especially where external mains disturbances or switching events are common. Configuration for 127/220 V Wye (4W+G) ensures compatibility with common plant power systems and simplifies wiring in existing panels. The single-module design reduces cabinet footprint and streamlines installation in new builds or retrofit projects, minimizing labor and material costs while maintaining clear protection boundaries for each phase and ground. Enclosure rated NEMA 4 with internal circuit breaker provides weather resistance and added protection against dust and water ingress. This feature reduces the need for outdoor cabinet upgrades and supports compliant installations in damp or dirty environments, even near washdown zones, while protecting the SPD's internal electronics and extending service life. Standard with surge counter enables real-time visibility into surge events without separate metering. This data improves asset management, supports maintenance planning, and aids root-cause analysis after disturbances. Engineers can correlate surge activity with equipment performance, driving targeted improvements in protection strategies. 15-year warranty from delivery, increasing to 20 years when registered on Eaton's SPD portal, reduces lifecycle risk and total cost of ownership. RoHS compliance ensures material-safety and easier supplier audits. Alongside UL 1449 and CSA certifications, this device aligns with procurement requirements for regulated industries and sustainability programs. Certifications like UL 1449 and CSA, plus RoHS compliance, help with risk management in critical facilities. The Max series single-module design supports modular upgrades across a site, while the built‑in surge counter simplifies compliance testing and maintenance planning.
