FAQs
SPD100208Y1N is designed for external sidemount installation on electrical distribution equipment. This enables mounting outside the main panel, reducing enclosure footprint and allowing direct protection of 120/208V four-wire systems. Follow manufacturer mounting guidelines and ensure proper clearance for heat dissipation and service accessibility to maximize reliability and safety during maintenance.
A 100 kAIC interrupt rating indicates the device can safely interrupt extremely high surge currents without compromising itself or downstream equipment. This translates to better protection of downstream transformers, switchgear, and sensitive electronics, reducing the likelihood of catastrophic damage during major surge events and improving uptime in high-energy environments.
Yes. The SPD100208Y1N uses a NEMA 4X enclosure designed for rugged indoor and outdoor exposure. This enclosure protects against dust, water, and corrosion, making it suitable for harsh environments such as loading docks, weather-exposed panels, and outdoor distribution equipment while maintaining performance integrity.
SPD100208Y1N is UL 1449 certified, ensuring surge protection performance and safety compliance. It is built to endure in standard industrial conditions with a 15-year warranty, providing long-term reliability and support for regulatory and facility-maintenance requirements.
ROI derives from reduced downtime, lower maintenance costs, and extended life of downstream equipment. The 100 kAIC protection, UL certification, and 15-year warranty translate to fewer outages and lower lifecycle costs, making this sidemount SPD a cost-effective choice for facilities prioritizing uptime and asset preservation.
