FAQs
Installation is straightforward with the SPD100220Y3A’s internal integrated mounting designed for Direct bus mounted panelboards. Ensure connections comply with 127/220 V (4W+G) rating and place the device on an accessible section of the panelboard. Verify 50/60 Hz operation and secure the unit to maintain proper clearance for heat dissipation. Use the surge counter for ongoing monitoring.
Key specs include 100 kA per phase surge current, 200 kAIC short-circuit rating, nominal discharge current 20 kA, operating voltages of 150 L-N, 150 L-G, 150 N-G, 300 L-L, and a voltage rating of 127/220 V (4W+G). It operates at 50/60 Hz, carries UL 1449 listing, and provides EMI/RFI filtering up to 50 dB from 10 kHz to 100 MHz.
Yes. The device’s EMI/RFI filtering reduces noise that can affect PLC and servo performance, while the 100 kA per phase surge protection and 300 V MCOV guard sensitive loads against transients common in industrial environments. Its compatibility with PRL direct bus panels simplifies integration into automation startups and upgrades.
The SPD100220Y3A is UL 1449 Listed, ensuring compliance with recognized safety standards for surge protection devices. It aligns with broader electrical protection expectations in industrial facilities, supporting reliable operation in harsh environments and contributing to safer, more maintainable power distribution networks.
The built-in surge counter provides verifiable protection history, aiding regulatory audits and maintenance planning. Coupled with a 15-year warranty, this reduces lifecycle risk and replacement costs, enabling predictable budgeting and minimized downtime, which improves overall return on investment for critical equipment and automated processes.
