FAQs
Installation starts with selecting a suitable enclosure and mounting in a clean, accessible panel. Connect conductors per the 240 delta (4W+G) configuration, observe proper grounding, and attach the unit to the panel according to Eaton’s wiring diagram. Verify tight torque on terminations and perform a functional check by simulating a transient to confirm proper response and fault isolation.
The SPM250240H1R delivers 250 kA per phase of surge protection. This high rating limits voltage rise during transient events, safeguarding sensitive drives, motors, and control circuits. In practice, it reduces nuisance tripping, minimizes wear on downstream components, and supports extended equipment life even in environments with frequent surges or lightning activity.
Yes. The unit uses a NEMA 4 enclosure designed for rugged, outdoor, and damp environments. Combined with its internal circuit breaker, it provides reliable protection and safe fault isolation in harsh facilities such as manufacturing floors, loading docks, and outdoor electrical rooms, helping maintain uptime in challenging conditions.
Compliance highlights include UL 1449 and CSA certifications, along with RoHS conformity. These standards support product safety and environmental requirements, making the SPM250240H1R suitable for regulated industrial settings and easy inclusion in compliant power protection audits and documentation.
The SPM250240H1R carries a 15-year warranty from the date of delivery. If you register the product on Eaton’s site, you extend coverage to 20 years. This extended warranty enhances ROI by reducing long-term maintenance risk and providing greater protection against component aging in critical power paths.
