FAQs
Install the device inside a compatible panel with a NEMA 4 rating or better. Ensure wiring to the 240 Delta (3W+G) system, connect to the internal terminal breaker, and observe proper clearance for heat dissipation. Refer to Eaton’s datasheet and install guides for torque specs and safe commissioning steps.
The SPM400240D1U provides up to 400 kA per phase with a two-module design configured for 240 Delta (3W+G). This arrangement delivers robust transient suppression across three phases while maintaining a grounded reference, reducing risk of equipment damage during voltage spikes.
Yes for heavy machinery and panel-based applications in manufacturing; however, data centers should evaluate their UPS and SPD topology. The unit’s 240 Delta configuration and NEMA 4 enclosure fit rugged environments, with a two-module layout offering scalable protection for expanding lines.
UL 1449 and UL 1283 listings, plus CSA C22.2 No. 8-M1986, verify electrical safety and surge protection performance. These certifications help satisfy regulatory requirements for industrial installations and support safe operation within controlled environments.
The SPD carries a 15-year warranty from delivery, extended to 20 years when registered on Eaton’s SPD site. This long-term coverage reduces maintenance costs, minimizes downtime, and protects critical assets, delivering a favorable total cost of ownership for durable protection.
