High surge capability provides robust protection for critical loads. SPD100480D2B delivers 100 kA per phase surge current and a 200 kA short-circuit rating for 480 V delta (3W+G) systems, reducing the risk of transformer and drive damage during lightning and switching events. This translates to lower downtime and longer equipment life, especially in MCCs and high-energy industrial applications. EMI/RFI filtering delivers up to 50 dB attenuation from 10 kHz to 100 MHz, resulting in cleaner control signals and more reliable PLC/SCADA performance, which minimizes nuisance trips in automated processes. The unit’s internal mounting and compact footprint streamline installation, enabling faster commissioning and easier retrofits in space-constrained switchgear. Audible alarm with silence button, Form C relay contact, and a surge counter with rest button support proactive maintenance and remote display integration.

FAQs
When integrating SPD100480D2B, ensure compatible 480 V delta (3W+G) switchgear and space for its 9.5 in L x 5.4 in W x 3.45 in H footprint. Verify mounting inside the equipment enclosure and verify remote display compatibility. Plan for wiring access to the internal integrated mounting and account for ambient temperatures of -40 to 50 °C. The unit’s 50/60 Hz rating suits global facilities and reduces configuration work during retrofits.
SPD100480D2B delivers 100 kA per phase surge capability and 200 kAIC interrupt rating for 480 V delta (3W+G) systems, with 640 V MCOV limits. This combination provides strong protection against lightning surges and switching transients while maintaining system uptime. The device also includes EMI/RFI filtering to minimize control signal disruption, improving overall reliability of drives and PLC-based controls in industrial setups.
Yes. SPD100480D2B is designed to be used with switchgear that has a remote display, enabling straightforward monitoring of surge events and device status. Features like a surge counter with rest button and Form C relay support integration with remote visibility systems, helping maintenance teams track performance, plan replacements, and verify fault causes without invasive probing.
SPD100480D2B carries UL 1449 and UL Listed certifications, indicating compliance with recognized safety and performance standards for surge protection devices. These certifications, along with compliance references to IBC, CBC, and UBC Zone 4 in its design context, provide assurance for code compliance, building safety, and risk mitigation in industrial facilities, which simplifies procurement and audit processes.
The device reduces maintenance intensity by providing clear electrical protection and diagnostic features such as a surge counter and audible alarms. With a 15-year warranty and robust surge/short-circuit ratings, capital expenditure is justified through lowered repair costs, reduced downtime, and extended switchgear life. In high-energy environments, the SPD helps stabilize critical loads and minimizes disruption to production lines.
