Special features
Basic
High surge handling delivers up to 120 kA per phase for a 480 Delta (3W+G) network. This level of transient suppression keeps sensitive drives, PLCs, and motor controllers from damage during voltage spikes, reducing unplanned downtime and extending equipment life. It’s well-suited for manufacturing lines, CNCs, and process controls where transients can propagate across three-phase systems. Rugged NEMA 4 enclosure with an internal circuit breaker simplifies outdoor or damp locations and streamlines service. It eliminates external disconnects, improves fault isolation, and accelerates maintenance windows, lowering labor costs. Single module footprint integrates easily into standard electrical cabinets and supports quick retrofit in mixed 480V delta installations, reducing mounting space and wiring complexity for faster commissioning. Certifications UL 1449, UL 1283, and CSA compliance reinforce regulatory alignment, with RoHS conformity and a 15-year warranty (20-year when registered) enhancing asset reliability and total cost of ownership. Installation-friendly design and documented performance specs support clean handoffs for system integrators and electrical contractors in North American projects.
