Eaton SPD100240D3C Surge Protection Device - UL Listed
Part Number: SPD100240D3C
Quick Summary
Eaton SPD series surge protection device protects electrical systems by clamping transients in switchboards, busways, and panelboards. Too often, unprotected equipment suffers nuisance outages and hidden damage from faults and lightning transients. Certified to UL 1449 and UL Listed, this SPD also integrates EMI/RFI filtering, a surge counter, and a Form C relay for proactive monitoring and rapid fault isolation. Compatible with switchboards, busways, and panel boards in PRL configurations, it delivers reliable protection without complicating installation. By combining protection with on-board monitoring and a compact footprint, it helps reduce downtime, extend equipment life, and lower maintenance costs for critical power feeds.

Feature → Business Impact → Application: SPD100240D3C delivers 100 kA per phase surge capability and a 200 kAIC short-circuit rating, protecting vital loads from large surges. This level of protection reduces unexpected downtime and extends downstream equipment life by absorbing transient energy at the source, making it ideal for 240V delta three-phase systems used in switchboards, busways, and panelboards (PRL1a–4). Feature → EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz reduces conducted noise that can disrupt drives, PLCs, and instrumentation, supporting smoother operation on manufacturing lines, automation cells, and robotics stations. Feature → Audible alarm with silence button and surge counter with rest button, plus a Form C relay contact, enable proactive maintenance and rapid fault isolation, reducing mean time to repair. Feature → Internal integrated mounting, compact footprint (9.5 in L × 5.4 in W × 3.45 in H) and 3.5 lb weight simplify retrofits and new installs in panel boards and switchgear. Feature → Operating temperature range of −40 to 50 °C and a 15‑year warranty provide long-term reliability in harsh environments and capital budgeting confidence.
