Feature → Business Impact → Application: The SPD100480D2G delivers a 100 kA per-phase surge current and a 200 kAIC interrupt rating, with 640 V L-G and 640 V L-L operating voltages. This capability limits damage from lightning and switching surges, reducing unplanned downtime and equipment replacement in industrial panelboards, especially in 480V delta systems such as manufacturing lines and distribution centers. EMI/RFI filtering provides up to 50 dB attenuation from 10 kHz to 100 MHz, improving drive and PLC reliability by minimizing conducted noise on control circuits, ideal for panelboards and control cabinets. An audible alarm with silence button, surge counter with rest button, and Form C relay contact enable proactive maintenance and rapid fault diagnosis. Right-terminal wiring and internal mounting simplify installation and reduce wiring errors in existing protective schemes. Meets or exceeds IBC 2006, CBC 2007, and UBC Zone 4 for compliant, resilient protection.

FAQs
Install the SPD100480D2G using the internal mounting, wiring it to the panelboard with the right-terminal configuration as specified. Ensure clearances per сайe requirements, connect to the PRL-C compatible bus, and verify terminal torque. After wiring, test the optional surge counter and confirm the audible alarm functions to verify protection integrity without disrupting normal operations.
Key specs include a 480V delta rating (3W+G), 100 kA per-phase surge current, 20 kA nominal discharge current, 200 kAIC interrupt rating, and 640 V L-G / 640 V L-L operating voltages. It operates at 50/60 Hz, within -40 to 50 °C, and supports panelboard protection with UL 1449, UL 1283, and UL Listed certifications.
Yes. It is designed for industrial 480V delta panelboards and is compatible with PRL-C panelboards. The device provides high-energy surge suppression, EMI/RFI filtering, and diagnostic features (surge counter, audible alarm, Form C relay), enabling reliable protection for drives, PLCs, and other critical equipment in manufacturing and processing facilities.
The device holds UL 1449, UL 1283, and UL Listed certifications. These indicate compliance with essential safety and performance standards for surge protection devices, reducing risk of failure, ensuring predictable behavior during transient events, and supporting regulatory compliance for industrial electrical installs.
Maintenance benefits include an audible alarm with silence button, a surge counter with a rest button for fault tracking, and a Form C relay contact for remote signaling. By mitigating surges, it reduces downtime, extends the life of protected equipment, and lowers repair costs, delivering a favorable return on investment for industrial facilities.
