Leroy-Somer Varistor Z380HPRL – Product Description

Overview
The Leroy-Somer Z380HPRL Varistor is a high-quality surge protection component engineered for use in Leroy-Somer brushless alternators. It protects the rotating rectifier and excitation system by absorbing and clamping dangerous voltage spikes generated during load variations, switching surges, or electrical faults. This ensures stable generator performance and prevents costly rectifier or diode failures.

Key Features

• Designed for Leroy-Somer LSA-series alternators

• High-energy MOV (Metal Oxide Varistor) for superior surge absorption

• Protects rotating rectifier diodes from transient over-voltage

• Compact, durable, and heat-resistant design

• Easy to replace during diode, rectifier, or excitation system maintenance

• Enhances alternator reliability and reduces downtime
