Eaton SPM400240D1R Surge Protection Device NEMA 4
Part Number: SPM400240D1R
Quick Summary
The Eaton SPM400240D1R surge protection device shields critical electrical systems from transients in industrial panels and facilities. Operators often face expensive downtime and equipment damage from spikes, and this unit mitigates that risk with robust, field-proven surge suppression. Certified to UL 1449, UL 1283 and CSA standards, it also aligns with RoHS requirements for safe, compliant installations. Its NEMA 4 enclosure and internal circuit breaker simplify installation, while a long warranty supports reliable operation and lowers total cost of ownership in industrial protection programs.

Special features
Basic
High-energy surge capacity of 400 kA per phase provides robust protection for PLCs, drives, and instrumentation, translating into fewer unscheduled outages and reduced repair costs. In a manufacturing line, this energy absorption means less wear on sensitive electronics and safer startup sequences. The unit uses a single module with a 240 Delta (3W+G) configuration, simplifying integration into three-wire systems and saving panel space while preserving wiring simplicity. The NEMA 4 enclosure with an internal circuit breaker ensures reliability in harsh environments and enables safer, easier mounting and maintenance. A 15-year warranty (20 years when registered) lowers lifecycle risk and total cost of ownership for continuous operations. RoHS compliance and certifications, including UL 1283, UL 1449, and CSA, help meet stringent regulatory and safety standards while supporting ongoing audits and compliance. With a compact footprint (50 lb, 9.3 in deep × 14.91 in wide × 17.5 in high), the SPM400240D1R integrates neatly into existing protection schemes and is compatible with Eaton’s SPD MAX series for scalable protection across facilities.

FAQs
Install the unit in a suitable panel space with a rigid mounting approach, connect the three-wire delta supply (3W+G) per the catalog drawing, ensure the internal circuit breaker is wired into the protection scheme, and verify compliance with NEC and local codes. Refer to Eaton’s specification sheet for wiring diagrams and torque values to avoid loose connections that could compromise protection.
400 kA per phase indicates the maximum surge current the SPD can safely divert per phase without damage. This rating supports protection for high-energy transients typical in industrial environments, reducing the risk of equipment failure and extending the life of sensitive devices like PLCs and drives.
Yes. The device is specified for 240 Delta (3W+G) systems, providing phase-to-ground protection in three-wire configurations commonly found in industrial machinery, control panels, and plant electrical rooms.
It carries UL 1449, UL 1283, CSA certifications, and RoHS compliance. These indicate safety and performance standards adherence, regulatory acceptance, and environmental compliance, which are critical for audit readiness, insurance, and installation in regulated facilities.
The device includes a 15-year warranty from delivery, extended to 20 years when registered on Eaton’s SPD site. Registration offers an extended protection window, supporting long-term reliability and a lower risk profile for plant protection investments.
