FAQs
Installation begins with confirming a 400Y/230V (4W+G) configuration and ensuring compatibility with 50/60 Hz systems. Use the internal integrated mounting and connect using the right terminals as specified. Verify L-N, L-G, N-G connections are properly routed and that the unit sits securely within the panel enclosure. Commissioning should include testing the surge counter and optional alarm signaling to confirm operation.
SPD100400Y3G carries UL 1449, UL 1283, and UL Listed certifications. These indicate rigorous testing for surge protection performance, electrical safety, and circuit reliability, which supports code compliance in commercial and industrial installations. For engineers and inspectors, this reduces project risk and streamlines acceptance testing in panelboard assemblies.
Yes, the SPD100400Y3G is designed for 50/60 Hz operation. It provides 100 kA per phase surge current, a 20 kA nominal discharge current, and a 400Y/230V (4W+G) rating with protection across L-N, L-G, N-G, and L-L paths. It’s intended for use with panelboards (PRL-C) and is compatible with standard industrial power architectures.
The unit includes an audible alarm with a silence button and a surge counter with a rest button, enabling quick fault notification and straightforward maintenance logging. A Form C relay contact supports remote signaling. These features help reduce downtime by providing immediate feedback on surge events and simplifying post-event analysis during scheduled maintenance.
By mitigating transient overvoltages, the SPD reduces the risk of routine equipment damage and unplanned outages, which lowers repair costs and downtime. The integrated counter and remote signaling capabilities improve maintenance planning, while compliance with UL standards reduces certification risk and supports longer-term asset life in grid-tied or critical process environments.
