SurgeStop+ 2.4kV-24kV Power System Protection RC Surge Snubber

Consider the APT Surge Snubber for your next surge protection device. It safeguards medium voltage generators, transformers, and motors by reducing the surge wave rise rate during switching or lightning surges. This protection helps prevent equipment damage and hazards. The snubber offers custom enclosure sizes for flexible mounting, a low-loss dielectric design, and high transient voltage withstand. It also features a 10‑second overvoltage rating compatible with our LZR‑series Neutral Grounding Resistor, with optional sensing and monitoring.
