Eaton SPD100240H1A Surge Protection Device - UL Listed
Part Number: SPD100240H1A
Quick Summary
The Eaton SPD100240H1A surge protection device safeguards panel boards against transient overvoltages in 240V delta systems. Without robust protection, electrical surges can trigger unplanned downtime, damaged drives, and costly maintenance across manufacturing lines. UL 1449 listing and UL Listed certification, along with code alignment to IBC 2006, CBC 2007, and UBC Zone 4, reinforce compliance. In practice, engineers gain predictable surge ride-through, extended equipment life, and simplified maintenance planning through a compact, internally mounted solution that integrates with direct bus mounted panels PRL1a, 2a, 3a, 3e. This combination delivers reliability, faster installation, and measurable ROI for industrial facilities.

High energy absorption and phase-specific protection are engineered to absorb 100 kA per phase surges without compromising downstream equipment, reducing unplanned downtime and warranty costs. The result is improved equipment uptime and longer life for drives, PLCs, motors, and sensors in critical automation lines, especially where 240V delta configurations are prevalent. The internal integrated mounting simplifies installation and minimizes field wiring, enabling faster commissioning on direct bus mounted panel boards PRL1a, PRL2a, PRL3a, and PRL3e. EMI/RFI filtering delivering up to 50 dB of attenuation improves control signal integrity, stabilizing PLCs and HMIs in noisy factory environments. A 200 kA short-circuit rating provides an additional safety margin while maintaining fast response during fault events. The audible alarm with a silence button, Form C relay contact, and a surge counter with a rest button give clear, actionable feedback for maintenance teams and building management systems. With operating range -40 to 50 °C and a 15-year warranty, this SPD is designed for demanding industrial environments, delivering predictable performance and reducing total cost of ownership.
