Eaton SPD100240D2H Surge Protection Device - UL Listed
Part Number: SPD100240D2H
Quick Summary
SPD100240D2H surge protection device safeguards electrical systems from transient overvoltages in panelboards and industrial equipment. Nuisance surges threaten uptime, risking equipment damage, nuisance tripping, and costly downtime for manufacturing lines. UL 1449 and UL 1283 listings underpin regulatory compliance, while EMI/RFI filtering provides up to 50 dB attenuation from 10 kHz to 100 MHz in demanding environments; it supports 240 V delta (3W+G) systems. Audible alarm with silence button, Form C relay contact, and a surge counter with rest button deliver fast diagnostics and protection without complicating wiring, while the standard feature package simplifies procurement for panelboards and control cabinets. This combination reduces commissioning time, extends equipment life, and delivers measurable ROI through improved reliability and easier maintenance.
