FAQs
The SPM320240H3S is designed for 240 delta (4W+G) systems and uses two modular protection blocks. For installation, mount the device in a compatible enclosure, connect the phase-to-ground and phase-to-phase wiring per Eaton’s guidelines, and verify the internal circuit breaker is in the ON position. Ensure the environment meets the NEMA 4 rating requirements for weather resistance in the intended location.
This SPD MAX device is UL 1449 and UL 1283 listed and CSA-certified, supporting CSA Electrical Notice No. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986. It is RoHS compliant, aligning with materials and manufacturing standards required for many regulated industries.
Yes. The enclosure is rated NEMA 4 with an internal circuit breaker, providing weather resistance and rugged protection suitable for outdoor or harsh indoor locations. This makes it appropriate for protecting outdoor panels, entrances to motor drives, and exposed power distribution equipment.
Key ratings include a 240 delta (4W+G) voltage configuration, two protection modules, and a surge capacity of 320 kA per phase. These ratings enable robust protection for critical loads such as drives and PLCs in demanding industrial environments.
The device carries a 15-year warranty from the date of delivery, with a 20-year warranty available when registered on Eaton’s site. This extended coverage supports lower maintenance costs and a clearer long-term return on investment for mission-critical protection.
