FAQs
SPD100480Y1Q uses an external sidemount design, allowing straightforward installation alongside existing distribution equipment. Connect L-N, L-G, N-G, and L-L as per the installation manual; the basic feature package simplifies wiring and mounting during retrofits. Ensure adequate clearance for accessibility and heat dissipation in the host panel.
The 100 kAIC rating indicates the device can safely interrupt and divert surge currents up to 100 kiloamps at their origin without compromising performance. This translates to better protection for downstream transformers, drives, and motors, reducing the likelihood of equipment damage during high-energy transients.
Yes. SPD100480Y1Q is UL 1449 listed and designed for 277/480V wye (4W+G) applications. This certification confirms electrical safety and performance under surge conditions, making it a dependable choice for code-compliant industrial installations.
The NEMA 4X stainless steel enclosure provides excellent protection against dust, water, and corrosion, making the SPD suitable for outdoor installations, washdown areas, and harsh industrial environments. Its rugged construction supports reliability in challenging plant conditions.
The 15-year warranty and UL-listed design reduce maintenance frequency and risk of unexpected failures. By preventing surge-related damage to sensitive equipment and minimizing downtime, this SPD lowers replacement costs and extends asset lifespans, delivering a favorable return on investment over the equipment’s operational life.
