FAQs
Install the SPM100240H4R in a suitable enclosure using standard panel mounting provisions. Connect the line and load conductors per the 240V high-leg delta configuration (4W+G on B phase), ensuring proper grounding. Verify the internal circuit breaker is engaged after wiring and perform post-installation testing to confirm surge protection operation. Follow local codes and Eaton’s wiring diagram for best results.
Yes. The unit is specified for 240V high-leg delta (4W+G) on the B phase, enabling straightforward integration with common delta-fed industrial equipment without complex reconfiguration. This compatibility supports motor controllers, MCCs, and distribution panels commonly found in manufacturing environments.
The SPM100240H4R delivers 100 kA per phase surge protection, providing strong transient suppression during voltage spikes from faults, switching, or lightning events. This rating helps prevent insulation damage, sensor faults, and downstream equipment failures, contributing to higher line reliability and reduced maintenance costs over time.
The device uses a NEMA 4 enclosure designed for harsh industrial environments, including washdown and outdoor applications. It also includes an internal circuit breaker, eliminating the need for an external disconnect and simplifying installation while improving protection against accidental energization.
With dimensions of 9.5 in depth, 17.05 in height, and 15 in width, and a weight of 52 lb, the SPM100240H4R is compact enough for retrofit in many existing panels while providing robust protection. The upfront fitment ease reduces installation time, and the 100 kA per phase protection supports longer equipment life and lower downtime, improving overall ROI.
