Feature → Business Impact → Application: The SPD100208Y3H delivers a high surge capability of 100 kA per phase with a 200 kAIC short‑circuit rating and a 20 kA nominal discharge current, protecting critical loads from dangerous transients while minimizing downtime and replacement costs in commercial and light industrial panels. This translates to improved equipment longevity and reduced maintenance cycles on 120/208V wye systems, especially in environments with frequent switching or lightning events. Application-wise, it suits panelboards (PRL-C) with four‑wire + ground configurations, benefiting data centers, manufacturing lines, and building automation where reliability is essential and EMI/RFI must be minimized. The device also features EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz, enhancing signal integrity for sensitive controls and sensors. Installation is further simplified by internal integration and left-terminal wiring, reducing wiring complexity and fault potential during retrofit projects. Additionally, the audible alarm with silence button, surge counter with rest button, and Form C relay contact offer quick status checks and remote signaling to maintenance systems, supporting proactive asset management and faster fault isolation.

FAQs
SPD100208Y3H is designed for panelboards and specifically used with PRL‑C configurations. It features internal integrated mounting and left-terminal (LT) wiring, simplifying installation and reducing wiring complexity in retrofit or new build projects. This compatibility supports streamlined onboarding for service teams and reduces installation time while maintaining code compliance.
Key specifications include a 100 kA per phase interrupt rating, 200 kAIC short‑circuit rating, 20 kA nominal discharge current, and a 120/208 V wye (4W+G) voltage rating. It operates at 50/60 Hz and provides up to 150 V between L-N, L-G, and N-G with 300 V MCOV between L-L. These figures define the protection level and compatibility with standard commercial/industrial power systems.
Yes. The SPD100208Y3H is UL listed and carries UL 1449 and UL 1283 certifications. These approvals validate performance and safety for use in building electrical distribution and support compliance with applicable codes and standards in many commercial/industrial environments.
Key considerations include leveraging the internal integrated mounting design and left-terminal wiring for faster, less error-prone installation. The device includes an audible alarm with a silence button, a surge counter with a rest button, and a Form C relay contact for remote signaling. EMI/RFI filtering up to 50 dB helps maintain sensor and control signal integrity, reducing nuisance trips and extending equipment life.
The unit provides robust transient protection, reducing downtime and equipment damage from voltage surges. It helps ensure regulatory compliance through UL certifications, supports longer asset life, and offers visibility via the surge counter. For operations relying on panelboard stability, the SPD delivers predictable maintenance costs and improved system reliability.
