FAQs
SPD100400Y1A is designed for direct bus mounted panelboards and integrates internally, enabling fast field installation with minimal additional hardware. Its mounting approach reduces wiring complexity and time-to-protect critical loads in modular panel assemblies, making it an ideal choice for modern industrial control panels that require compact protection without bulky external enclosures.
The device provides 100 kA per phase surge current with a 200 kAIC interrupt rating, along with a nominal discharge current of 20 kA. These specifications deliver robust transient protection for 400Y/230V systems, helping prevent damage to downstream equipment during high-energy events.
SPD100400Y1A carries UL 1449 certification and UL Listed status, ensuring compliance with recognized safety standards. It also aligns with IBC 2006, CBC 2007, and UBC Zone 4 for code compliance in applicable installations, providing engineers with confidence in safety, reliability, and regulatory adherence for commercial and industrial projects.
Install the SPD as an internal integrated unit within direct bus mounted panelboards to minimize wiring and exposure. Ensure operation within -40 to 50 °C, and plan for EMI/RFI filtering benefits in environments with electrical noise. Regularly verify the audible alarm and the Form C relay signaling to maintain proactive monitoring and prompt fault notification.
By reducing the likelihood of surge-related damage, downtime, and costly repairs, SPD100400Y1A lowers lifecycle costs for critical electrical infrastructure. The 15-year warranty and UL certification further strengthen asset protection, while improved reliability supports higher productivity in data centers, manufacturing, and utility facilities.
