FAQs
Installation is streamlined by the SPD100400Y2A’s internal integrated mounting and standard feature package designed for PRL series direct bus mounted panelboards. Position the unit adjacent to the main distribution bus, connect line and neutral leads as per the 400Y/230V rated configuration, and verify the EMI/RFI filtering components are properly seated. Use the Form C relay contact and surge counter for status reporting to BMS or maintenance logs. Ensure ambient temperature stays within -40 to 50 °C for reliable operation.
Yes. SPD100400Y2A is specified for 400Y/230V (4W+G) systems and supports both 50 Hz and 60 Hz operation. The device is designed for direct bus mounted panelboards and provides 100 kA per phase surge capability, with a 320 L-N, 320 L-G, 320 N-G, and 640 L-L operating voltage set. This makes it suitable for a wide range of industrial electrical protection scenarios.
SPD100400Y2A carries UL 1449 Certification and UL Listed status, demonstrating conformance to established safety and performance standards for surge protection devices. These certifications support compliance with electrical installation codes and procurement requirements in industrial facilities, helping auditors and specifiers validate protective measures without additional testing.
The SPD100400Y2A provides EMI/RFI filtering with up to 50 dB attenuation from 10 kHz to 100 MHz. This reduces electrical noise that can interfere with PLCs, drives, sensors, and control networks, leading to more stable operation, fewer nuisance trips, and improved data integrity in automation systems.
The unit comes with a 15-year warranty, reflecting Eaton’s confidence in long-term reliability. Maintenance implications include monitoring the audible alert status, periodically testing the surge counter, and ensuring the direct bus mounted connections remain secure. Routine checks support reduced downtime and predictable maintenance planning.
