FAQs
Installers should power down the panel, verify space for a 17.5 in height by 14.91 in width by 9.3 in depth footprint, and mount the unit within the NEMA 4 enclosure as specified. Connect conductors per 240V delta (4W+G) with appropriate sized lugs, then arm the internal circuit breaker. After mounting, perform a visual inspection and test per Eaton’s datasheet and your control panel’s wiring standards.
SPM100240H1R delivers 100 kA per phase surge capability, designed for 240V delta (4W+G) configurations. This rating translates to powerful transient suppression for motors, drives, PLCs, and contactors, reducing the risk of insulation damage and unexpected equipment failures during lightning or switching events, and supporting ongoing production uptime.
Yes. The SPM100240H1R is specified for 240V delta with a 4W+G high-leg arrangement, providing targeted protection for the B phase high-leg while maintaining full protection of connected loads. Its internal circuit breaker also aids in safe servicing after a surge event, making it a good fit for systems with high-leg delta wiring in manufacturing floors.
The device carries RoHS compliance and multiple certifications, including UL 1283 and UL 1449, as well as CSA standards (C22.2 No. 8-M1986) and CSA Electrical Notice No. 516 Edition 1. These certifications help ensure regulatory compliance, safety, and compatibility with international electrical codes for industrial installations.
The SPM100240H1R offers a 15-year warranty from the date of delivery, rising to 20 years if registered on Eaton’s SPD site. This extended coverage reduces maintenance and replacement costs over the asset life. Combined with its robust surge rating and durable enclosure, the unit delivers predictable TCO for mission-critical panels and automation equipment.
