This SPD combines a high interruption rating with reliable protection. Its 100 kA per phase surge capability and 200 kAIC short-circuit rating shield critical loads from lightning and utility switching events, reducing downtime and warranty costs. EMI/RFI filtering delivers up to 50 dB of noise attenuation from 10 kHz to 100 MHz, improving controller precision and signal integrity in noisy plant environments. An audible alarm with a silence button provides immediate fault awareness without compromising workflow, while a Form C relay contact enables easy integration with building management and annunciation systems. The internal mounting design suits Direct bus mounted panelboards PRL1a, 2a, 3a, 3e, simplifying installation and service. A 15-year warranty reinforces lifecycle value.

FAQs
The SPD100220Y1A is designed for internal mounting within PRL1a, PRL2a, PRL3a, and PRL3e assemblies. Start by verifying panelboard compatibility, ensuring power is off, then mount the device using the internal mounting method. Connect L-N, L-G, and N-G conductors per the rated 127/220 V configuration, and integrate the Form C relay and alarm contacts with your supervisory or annunciation system. Finally, test with the surge counter and perform a field check for compliance with UL 1449 guidelines.
This SPD provides a 100 kA per phase surge rating and a 200 kAIC short‑circuit rating, with a 20 kA nominal discharge current. In a transient event, energy is diverted away from protected circuits, reducing voltage spikes on L-N, L-G, N-G, and L-L paths. This helps prevent insulation damage, motor nuisance trips, and premature component failure across industrial controls and drives.
Yes. The unit is specified for 127/220 V Wye systems with four conductors plus ground (4W+G) and operates across 50/60 Hz. Its internal integration and compatibility with Direct bus mounted panels streamline installation in manufacturing lines, data centers, and process equipment where reliable transient protection is critical.
The SPD100220Y1A carries UL 1449 Listed certification and UL Listed status, supporting safety and compliance in many regions. It also meets performance expectations referenced by IBC 2006 and CBC 2007. For maintenance, rely on built-in features such as the audible alarm, surge counter, and EMI/RFI filtration to monitor health and ensure ongoing protection.
Although price varies by region, the SPD100220Y1A offers a long 15‑year warranty and a robust protection package that minimizes unplanned downtime and repair costs. Its compact internal mounting reduces enclosure space needs and simplifies service within PRL panel ranges, delivering a favorable return on investment through reduced outages and maintenance labor.
