High surge and interrupt ratings deliver real-world protection. The SPD100240D3H supports 100 kA per phase surge current and a 200 kAIC short-circuit rating, with 320 V L-G and L-L MCOV and 240 delta (3W+G) rating at 50/60 Hz, helping prevent cascading failures and costly outages in panelboards. This translates to reduced equipment wear, extended service life, and lower total cost of ownership in manufacturing lines and critical facilities. Integrated protection features accelerate maintenance and response times; it includes an audible alarm with silence button, a surge counter with rest, and a Form C relay contact for immediate annunciation to plant systems, improving uptime and operator awareness. EMI/RFI filtering delivers up to 50 dB of noise attenuation from 10 kHz to 100 MHz, ensuring cleaner power for sensitive controls and PLCs. Compatibility with standard panelboard configurations and left-terminal wiring simplifies retrofits and现场安装, reducing install time by hours and minimizing field wiring errors. The unit is designed for internal mounting, with a compact footprint that fits tight panel spaces while delivering reliable protection for 240 V delta systems and 320 L-G/L-L circuits. A robust feature set— combined with panelboard compatibility (PRL-C) and a warranty-friendly design (Left Terminal Warranty Replacement)—addresses common industry objections about retrofit feasibility and long-term support. Modeling real-world environments, the SPD100240D3H supports demanding industrial settings, meeting IBC/CBC/UBC considerations and offering measurable protection against transient events and nuisance faults.

FAQs
SPD100240D3H is designed for panelboard usage, specifically compatible with PRL-C configurations. It features left-terminal wiring and internal mounting, which simplifies retrofits and new installations alike. With a 12 in length/depth footprint and a 12 in width, it fits typical panel enclosures while delivering robust surge protection for 240 V delta (3W+G) systems and 320 L-G/L-L circuits.
Expect 100 kA per phase surge current with a 200 kAIC short-circuit rating. The device provides 320 V L-G and L-L MCOV, a 20 kA nominal discharge current, and operates at 50/60 Hz. These specs translate into strong protection for critical loads, reduced damage from transient events, and lower risk of production interruptions.
The SPD100240D3H carries UL 1449 and UL 1283 certifications and is UL Listed, signaling compliance with widely recognized safety and performance criteria for surge protective devices used in electrical systems and panelboards.
Installers should note the left-terminal configuration and internal mounting method for streamlined wiring. The device is rated for 50/60 Hz operation, works with panelboards (PRL-C), and has a footprint suitable for standard compartments. It contributes minimal space impact while providing integrated features like an audible alarm and surge counter for proactive monitoring.
By limiting transient overvoltages and filtering EMI/RFI, the SPD100240D3H reduces equipment wear, downtime, and maintenance costs. Its surge counter and form C relay support proactive alarm signaling, while UL-listed protection helps meet safety and regulatory expectations, delivering measurable uptime improvements and longer asset life in manufacturing and critical process control environments.
