Special features
Basic
High surge rating with two modules provides robust protection for critical loads, reducing the risk of equipment damage and downtime in demanding applications. This translates to fewer unscheduled outages and lower repair costs in manufacturing lines, packaging machines, and process controls. The NEMA 4X enclosure with an internal circuit breaker enables safe, reliable installations in harsh environments, including outdoor panels or wash-down areas, while simplifying fault isolation and service. The device carries RoHS compliance along with UL 1449, UL 1283, and CSA certifications, supporting regulatory audits and component traceability across global supply chains. A 15-year warranty (20 years when registered with Eaton) improves total cost of ownership by delaying replacement cycles and protecting long-term capital investments. The two-module design and compact form factor ease retrofit and new-build deployments in existing switchgear and control cabinets, reducing installation time and associated labor costs.

FAQs
The SPM400240D1W is designed for 240 Delta (3W+G) configurations and fits standard electrical protection layouts. Plan for two modules in a compact enclosure, ensuring the internal circuit breaker is accessible for quick fault isolation during commissioning.
It provides up to 400 kA per phase surge protection and carries UL 1449 and UL 1283 certifications, plus CSA Electrical Notice and CSA standards recognition, offering robust regulatory compliance for industrial installations.
Yes. The unit uses a NEMA 4X enclosure, designed to withstand wet, dusty, and corrosive environments, with an internal circuit breaker for safe operation and easier maintenance.
Its two-module design simplifies retrofits and new installs, while the RoHS compliance and long warranty (15 years, 20 years with registration) reduce lifecycle risk and maintenance costs. The internal breaker also streamlines fault diagnostics without external accessories.
By protecting critical loads from transients, it lowers downtime, preserves sensitive equipment, and extends asset life. The long warranty and certified compliance support lower total cost of ownership while improving reliability across industrial controls and drives.
