Special features
Standard with surge counter
High surge current rating of 300 kA per phase gives you headroom for both lightning transients and heavy switching surges, reducing the risk of downstream equipment damage. This translates into fewer outages, lower repair costs, and improved uptime for critical lines such as CNC machines or data-center feeds. The single module with an internal terminal breaker and a rugged NEMA 4 enclosure simplifies installation in many environments—from outdoor panels to damp plant rooms. For installers, the integrated wiring path minimizes field modifications and speeds up commissioning without compromising protection. A standard surge counter enables proactive maintenance and regulatory traceability, helping teams confirm ongoing protection and plan replacements before failures occur. UL 1449, CSA, UL 1283 certifications and RoHS compliance provide regulatory alignment and risk mitigation. Extended warranty of 15 years, up to 20 years when registered, adds long-term cost savings and predictable budgeting. The 120/240 V split-phase rating makes it compatible with many commercial and light-industrial distribution systems, and its RoHS and UL listings support cross-site deployments.
