High surge rating per phase provides robust protection against transient overvoltages, reducing the risk of downstream equipment damage and unplanned downtime. This translates to improved line uptime and longer service intervals for critical gear in demanding industrial environments. The compact form factor (3.48 in depth x 7.47 in width x 12.05 in height) and a 6.8 lb weight simplify mounting within crowded panels, accelerating installation and enabling easier retrofits in legacy switchgear. Compatibility with Power Xpert SPD and switchgear featuring a remote display enables real-time monitoring and remote diagnostics, improving maintenance planning and reducing on-site visits. The 240V high-leg delta (4W+G) configuration supports modern plant architectures while delivering reliable protection for motors, drives, and control circuits. UL 1449 certification reinforces safety and compliance, aiding supplier qualification and procurement approvals. The device’s rated 100 kA per phase protection minimizes nuisance tripping and ensures stable power delivery to essential loads.
