High-energy surge tolerance: The SPD100240D3D delivers 100 kA per phase surge current, protecting critical drives, PLCs, and controllers from damaging transient voltages. Business impact includes reduced component replacements and longer equipment life, especially in demanding manufacturing environments where 3W+G delta configurations are common. Application focus is 240V delta panelboards and distributed load centers, where dependable surge protection translates directly to uptime and productivity. Comprehensive electrical ratings: With 320 V L-G and 320 V L-L operating voltages and 50/60 Hz compatibility, this device supports typical industrial control networks while sustaining performance across temperature and duty cycles. The 200 kAIC short-circuit rating further reinforces system resilience, limiting fault propagation and safeguarding feeders. This makes it suitable for panelboard upgrades and new installations in warehouses, facilities, and assembly lines.Integrated monitoring and signaling: An audible alarm with silence button, a Form C relay contact, and an internal surge counter with a rest button offer straightforward status visibility and fault tracing. These features streamline preventive maintenance planning and enable rapid response during surge events, reducing unplanned downtime and service calls in mission-critical lines.EMI/RFI filtration for cleaner signals: Up to 50 dB of noise attenuation from 10 kHz to 100 MHz helps protect sensitive controls and communication links. This is particularly valuable in automated equipment where controller radios, drives, and sensors share noisy electrical environments, improving reliability and data integrity.Installation efficiency and compatibility: Bottom terminals (BT) and an internal integrated mounting design simplify wiring in tight spaces and minimize enclosure depth. This supports faster installation, lower labor costs, and compatibility with panelboards like PRL-C, enabling compact, scalable protection for growing industrial networks.

FAQs
SPD100240D3D is designed for 3-phase 240V delta installations and features bottom terminals (BT) to simplify wiring routes. When planning installation, ensure proper clearance for mounting, observe conductor insulation requirements, and route sensor/communication lines away from high-current conductors. The internal mounting supports a clean, compact footprint, reducing enclosure depth and making field wiring faster and more reliable.
Key ratings include 100 kA per phase surge current, 200 kAIC short-circuit rating, and 320 V L-G / 320 V L-L operating voltages at 50/60 Hz. Nominal discharge current is 20 kA. These specifications shield drives, PLCs, and control electronics from transient events, while the EMI/RFI filtering further reduces noise that could impact control accuracy and communication reliability.
The SPD100240D3D carries UL 1449 and UL 1283 listing and is designed to meet or exceed IBC 2006, CBC 2007, and UBC Zone 4 requirements. Compliance with these standards ensures safer operation, reliable overvoltage protection, and compatibility with regulated electrical installations, helping facilities meet regulatory and safety obligations while maintaining warranty coverage.
