FAQs
Install the SPD100240D4M inside a suitable enclosure, preferably a NEMA 1 enclosure with an internal disconnect for service access. Connect the three phase conductors and the ground to the device per the panel schematic, ensure correct polarity, and verify the UL 1449 labeling. Follow local codes, secure all terminations, and test operation after wiring to confirm proper surge protection activation.
100 kA per phase means the device can withstand high-energy transients per phase, providing substantial protection against damaging surges from utility events or switching. This rating translates to longer equipment life, reduced repair costs, and lower risk of nuisance trips in environments with frequent electrical disturbances, such as machine rooms and line-side power panels.
Yes. The SPD100240D4M is designed for use with NEMA 1 enclosures and includes an internal disconnect option, simplifying serviceability and safe maintenance access. This makes it well-suited for industrial control panels where quick isolation of protection components is desired during diagnostics or replacement without exposing personnel to live circuits.
The device is UL 1449 listed, providing recognized safety and performance validation for surge protection devices. It is designed for industrial environments and is compatible with Eaton’s Power Xpert SPD ecosystem, helping ensure reliable protection across Eaton protection products and simplifying compliance and documentation for audits.
While exact ROI depends on site-specific surge frequency and equipment value, the SPD100240D4M reduces downtime, extends the life of connected equipment, and lowers maintenance costs by preventing surge-related damage. Routine checks focus on visual inspection and connection integrity; the UL 1449 listing supports long-term reliability and regulatory compliance.
