FAQs
Install the SPD100480D4N in a standard electrical cabinet with adequate space for ventilation. Mount upright in the enclosure, connect line, neutral, and ground terminals per the Eaton installation guide, and ensure proper cable routing to minimize EMI. Verify UL 1449 compliance, tighten terminals to the recommended torque values, and perform a continuity check before energizing the system.
Yes. The device is designed for 480V delta (3W+G) systems and offers 100 kA per phase surge capability, delivering robust protection for motors, drives, and associated control panels in manufacturing and processing environments. For best results, coordinate with upstream protection and ensure panel ratings match the protection strategy.
A 100 kA per phase rating means each phase can safely absorb up to 100 kiloamps of surge energy without device failure. This translates to superior transient suppression for high-energy events, reducing the likelihood of insulation breakdown, drive damage, and motor faults in demanding industrial conditions.
Yes, the SPD100480D4N is UL 1449 listed, indicating compliance with recognized safety standards for surge protective devices. This certification supports reliability in industrial installations and helps streamline procurement and safety audits for facilities employing NEMA 4 enclosures in harsh environments.
By limiting transient events that shorten equipment life, the SPD100480D4N reduces drive and motor failures, lowers maintenance costs, and minimizes unplanned downtime. The predictable protection also simplifies procurement and spares planning, supporting faster project approvals and a clearer path to achieving uptime targets across production lines.
