The SPD100480D1L delivers a high surge capacity with a 100 kAIC interrupt rating, providing fast clamping and safe dissipation of surge energy. This reduces the risk of insulation damage to transformers and motors, improving uptime for critical manufacturing lines and mission-critical equipment. It is designed for 480V delta systems and features a 640 V-L-G and 640 V-L-L operating range, enabling reliable protection across common industrial feeders while accommodating mixed Three-Wire Plus Ground configurations. The rugged NEMA 1 flush enclosure and external side-mount installation simplify retrofits and new builds, enabling rapid deployment in control cabinets and distribution panels without altering existing infrastructure. UL 1449 listing and a 15-year warranty offer long-term compliance and predictable lifecycle costs, making this SPD a cost-effective component in quality-assurance programs. Documentation and installation resources, including brochures and datasheets, support procurement and field commissioning, reducing the risk of misapplication. In practice, users see fewer nuisance trips, extended asset life for drives and transformers, and streamlined maintenance planning for 480V protection schemes. This aligns with industry best practices for external protection devices and SPD series compatibility in modern facilities.

Use the provided installation manual IM01005031E.pdf for mounting steps, wiring diagrams, and safety precautions to prevent misapplication and ensure compliant, reliable surge protection.
Yes. This device is rated for 480V delta systems (3W+G) with a 640 V L-G and 640 V L-L operating voltage and a 100 kAIC interrupt rating, making it appropriate for motor feeders, drives, and control cabinets in demanding manufacturing environments seeking robust surge suppression.
The SPD100480D1L carries UL 1449 listing for surge protection devices and is designed with a NEMA 1 indoor enclosure. Its 15-year warranty further supports long-term reliability and compliance with typical industrial protection programs. Always verify project-specific standards, but this model is aligned with common U.S. electrical protection requirements.
By limiting voltage spikes, the SPD reduces nuisance trips and insulates downstream equipment from surge damage, lowering maintenance costs and extending the life of motors, transformers, and drives. Over time, this translates to higher equipment availability, less unplanned downtime, and a favorable return on investment within 3–5 years in many industrial settings.
