Eaton SPD100240D2C Surge Protection Device - UL 1449 Listed
Part Number: SPD100240D2C
Quick Summary
The Eaton SPD100240D2C surge protection device protects critical electrical systems from transient surges in switchboards, busways, and panel boards. This targeted protection helps prevent nuisance outages, motor stalls, and accelerated equipment wear caused by voltage spikes. UL 1449 Listed certification underlines safety and reliability, while EMI/RFI filtering reduces electrical noise that can affect PLCs and drives. With 320 L-G, 320 L-L MCOV and a 100 kA per phase rating, it delivers robust clamping for 50/60 Hz networks. The 15-year warranty and internal diagnostics support ongoing maintenance programs, and its internal mounting simplifies retrofits and new installations in modern industrial facilities while maintaining a compact form factor and compatibility with PRL series enclosures.

High surge capability translates to fewer interruptions and longer life for critical loads. The SPD100240D2C delivers 100 kA per phase, a 200 kAIC short-circuit rating, and a 20 kA nominal discharge current, enabling rapid, reliable clamping across 50/60 Hz systems. In switchboards, busways, and panel boards, this means motors and drives stay protected during severe transient events. EMI/RFI filtering delivers up to 50 dB attenuation from 10 kHz to 100 MHz, reducing interference with PLCs, HMI, and drives; the result is steadier control signals and fewer fault trips in precision manufacturing lines. An audible alarm with silence button and a Form C relay provide immediate fault signaling, while a surge counter with rest button supports proactive maintenance planning. The internal integrated mounting and compact footprint simplify retrofits and new installations, saving time in space-constrained enclosures. With a 15-year warranty, this protection solution offers long-term reliability for demanding industrial environments.

FAQs
The SPD100240D2C features internal integrated mounting for straightforward installation. It fits standard enclosures and is compatible with switchboards, busways, and panel boards (PRL1a, 2a, 3a, 3e, 4). Begin with de-energizing the panel, secure the unit in a suitable space, make the L-L and L-G connections per the datasheet, and verify the 50/60 Hz supply and proper grounding before enclosure re-energization. This approach minimizes wiring time and speeds retrofits.
Expect 100 kA per phase surge current with a 200 kAIC short-circuit rating and a nominal discharge current of 20 kA. The device is rated for 240 V delta (3W+G) with 320 L-G and 320 L-L MCOV and operates at 50/60 Hz. These specs ensure robust protection for motors, drives, and controls against transients common in industrial power systems.
Yes. The unit is designed specifically for 240V delta networks (3W+G) and provides reliable protection for manufacturing environments. Its 320 L-G / 320 L-L MCOV ratings and 100 kA per phase surge capability make it suitable for protecting switches, panel boards, and busways that power conveyors, robotics, and automation systems.
SPD100240D2C carries UL 1449 Listed certification, a recognized standard for surge protective devices. This certification helps ensure safety and reliability in industrial installations and supports compliance with electrical safety requirements for panel boards and switchgear. The product is also designed to meet building and interconnection standards commonly used in heavy industry.
The device includes an audible alarm with a silence option, a Form C relay contact for remote signaling, and a surge counter with a rest button for event tracking. Together with a 15-year warranty, these features enable proactive maintenance planning, rapid fault diagnosis, and long-term protection for critical loads in facilities using switchboards and panel boards.
