Eaton’s SPD Series (Sidemount Versions) Data Sheet
Feature: 100 kAIC interrupt rating delivers robust transient protection. Business impact: safeguards downstream equipment from surge energies common in industrial facilities, reducing unplanned outages and spare-part costs. Application: ideal for distribution panels, motor drives, and PLC cabinets in demanding, 24/7 environments. Feature: 240V delta (3W+G) voltage rating ensures correct protection alignment with the system. Business impact: simplifies protection strategy by matching the actual service voltage, reducing misapplication risk and installation rework. Application: best suited for 3-wire delta arrangements in manufacturing floors, data centers, and process lines. Feature: NEMA 1 enclosure with internal disconnect provides safe, indoor protection and enables service-friendly isolation. Business impact: improves maintenance readiness and minimizes exposure during panel servicing. Application: panel boards and control cabinets where operators need quick disconnect during fault events. Feature: External side mounting supports flexible placement without heavy enclosure modifications. Business impact: speeds retrofits, lowers installation labor, and enables closer proximity to protected loads. Application: retrofit projects and new builds where space is at a premium in electrical rooms. Feature: UL 1449 certification and 15-year warranty provide regulatory confidence and long-term ROI. Business impact: reduces compliance risk and total cost of ownership while providing peace of mind to procurement teams. Application: project specs and maintenance contracts for critical facilities. Feature: Compact size and weight (9.5 in L, 5.4 in W, 3.45 in H; 3.5 lb) support easy integration into existing assemblies. Business impact: minimizes space impact on crowded panels and simplifies inventory planning. Application: retrofit and new installations where space constraints are a concern.

FAQs
This device is designed for external side mounting on 240V delta (3W+G) systems with a NEMA 1 indoor enclosure. Follow the provided installation manual and Eaton datasheet to ensure proper mounting, wiring, and internal disconnect usage. Typical retrofit projects benefit from its compact footprint and straightforward wiring scheme.
SPD100240D1M provides a 100 kAIC interrupt rating, enabling robust protection against high-energy transients. It clamps spikes and divert fault currents away from downstream equipment, reducing insulation stress, extending motor and drive life, and minimizing nuisance trips in demanding production environments.
Best suited for 240V delta (3W+G) distribution panels, motor starters, and industrial control cabinets. Its external side mounting and NEMA 1 enclosure make it well-suited for indoor electrical rooms in manufacturing, process lines, and facility distribution where reliable surge protection and fast fault isolation are required.
The device carries UL 1449 certification for surge protection safety, plus Eaton’s 15-year warranty. This combination supports regulatory compliance, long-term reliability, and a favorable total cost of ownership for mission-critical facilities.
By reducing transient damage and downtime, this SPD improves uptime and productivity. The internal disconnect simplifies servicing, while the UL certification and extended warranty provide predictable maintenance costs, contributing to a lower total cost of ownership over the equipment’s life cycle.
