FAQs
Begin with verifying panel compatibility for 400Y/230V, 4W+G, and left-terminal mounting. Mount the SPD internally in the panel, connect L-N, L-G, and N-G per the schematic, then enable the surge counter and test the audible alarm. Use the Form C relay for signaling and ensure the device is within −40 to 50 °C operating range for reliable operation.
The device offers 100 kA per phase surge current, a 200 kAIC short-circuit rating, and a nominal discharge current of 20 kA. It operates at 50/60 Hz with an 400Y/230V (4W+G) rating and provides 320 L-N, 320 L-G, 320 N-G, and 640 L-L MCOV for comprehensive protection.
Yes. SPD100400Y3H is designed for panelboards (PRL-C) and 400Y/230V four-wire systems. It features left terminals and an internal integrated mounting, making it straightforward to install in existing enclosures while delivering expansive transient protection and an integrated surge counter.
The device carries UL 1449, UL 1283, and UL Listed certifications, signaling adherence to recognized safety and reliability standards. This matters for code compliance, insurance considerations, and trusted performance in critical electrical installations across industrial facilities.
Benefits include a built‑in surge counter with rest button for traceable event logging and an audible alarm for immediate fault notification. The Form C relay support enables remote signaling. Routine inspection after large surges and adherence to warranty guidance help maximize uptime and protect downstream equipment.
