Special features
Standard with surge counter
The Max series provides robust protection for demanding power networks with a 200 kA per phase surge rating on 277/480 V Wye systems. This single-module design concentrates surge mitigation at the point of entry, helping downstream drives, PLCs, and motors survive transient events. In industrial environments, this level of protection translates to reduced nuisance tripping, less equipment wear, and fewer emergency service calls during voltage disturbances. It’s well suited for manufacturing lines and critical plant feeders.Durability and installation ease come from a NEMA 4 enclosure with an internal terminal breaker, enabling reliable outdoor and rugged indoor service. The unit fits in standard 4W+G panels, with a predictable footprint (9.3 in depth, 17.5 in height, 14.91 in wide) and a 50 lb weight that supports quick field retrofits without enclosure upgrades. This design minimizes disruption during upgrades and shortens commissioning time.A built-in surge counter provides real-time monitoring and historical event tracking, supporting proactive maintenance and regulator audits. The device is RoHS-compliant and carries UL 1449, UL 1283, and CSA certifications, delivering tested performance data to simplify compliance. Quick wiring, durable contacts, and a well-documented installation procedure reduce risk during expansion projects and improve overall protection certainty.Compatibility and maintenance advantages include seamless integration with Eaton Max series infrastructure and other 4W+G systems, minimizing wiring complexity and spare-part overlap. The RoHS compliance reduces regulatory concerns, while UL/CSA approvals streamline supplier qualification and audits. The result is faster deployment, fewer revision cycles, and reliable protection for mixed automation environments, from robotic cells to packaging lines.Warranty and lifecycle value are substantial. Eaton offers a 15-year warranty from delivery, with a 20-year option upon registration, reflecting confidence in long-term performance. This coverage, together with the surge counter and durable enclosure, reduces risk of unexpected replacement costs and supports total-cost-of-ownership targets. For plant managers, the combination translates to improved asset reliability, predictable maintenance budgeting, and higher uptime for mission-critical equipment.
