This document introduces the features and characteristics of the PA series transient surge suppressor products, including the wide operating voltage range, creep and strike distance capability, base mount construction, quick connect tab terminal and no derating ambient temperature
The PA Series of base‑mount metal‑oxide varistors (MOVs) are designed for vibration‑prone applications. They feature a rigid base‑mount package with a quick‑connect tab terminal that also serves as the chassis ground connection, and meet rigid NEMA standards for creep and strike distance.
The series covers a wide range of operating voltages (130 V to 660 V AC RMS) and offers high peak pulse current capability (up to 6500 A for an 8/20 µs waveform). Detailed specifications include absolute maximum ratings, power‑dissipation limits, mechanical dimensions, and recommended mounting hardware.
| Operating Voltage Range (AC RMS) | 130 V to 660 V |
|---|---|
| Operating Ambient Temperature Range | -55 °C to 85 °C |
| Creep and Strike Distance Capability | Meets rigid NEMA standards |
The PA Series varistors operate from 130 V to 660 V AC RMS.
It uses a base‑mount construction with a quick‑connect tab terminal that also serves as the chassis ground.
The PA Series is recognized by UL (E75961) and CSA (LR91788).
