FAQs
For 240V delta (4W+G) configurations, mount the SPM250240H1T in a suitable enclosure with adequate clearance. Utilize the internal terminal breaker to streamline wiring, verify RoHS and regulatory compliance, and ensure compatibility with existing suppression networks within the panel. Consider downstream protection coordination to optimize reliability during transients.
The 250 kA per phase rating means the device can absorb substantial transient energy without compromising downstream equipment. This translates to reduced likelihood of insulation damage, fewer protective blows to the main drives, and lower repair or replacement costs after lightning or switching surges in industrial facilities.
Yes. The unit uses a NEMA 4 enclosure suitable for wet, dusty, and demanding industrial environments. It carries UL 1449 and UL 1283, CSA Electrical Notice No. 516 Edition 1, CSA Std. C22.2 No. 8-M1986, and RoHS compliance, offering robust regulatory alignment for global deployments.
The SPD MAX device carries a 15-year warranty from delivery, extending to 20 years when registered on Eaton’s SPD portal. This longevity reduces replacement cycles and maintenance costs, contributing to a lower total cost of ownership, especially in facilities with high surge exposure.
By minimizing transient damage, preventing unplanned downtime, and protecting critical equipment like motors and drives, the SPM250240H1T helps sustain production throughput. The combination of high surge rating, reliable enclosure, and long warranty delivers measurable uptime gains and lower total maintenance expenses over the asset lifecycle.
