Multiquip 0601822664 ZNR Varistor

The Multiquip 0601822664 ZNR Varistor is a genuine OEM electrical protection component designed for Multiquip DCA and MQP series generators, including super-silent and ultra-silent models such as the DCA36SPXU4F, DCA45SSIU4F, DCA70SSJU4F, DCA70USI2, and MQP56, among others. As a direct OEM replacement, this varistor meets the original electrical specifications required to protect the generator's control circuitry from voltage transients and surges. Sourced directly through authorized Multiquip supply channels, part number 0601822664 ensures you are installing the correct component for your specific generator model. DHS Equipment stocks genuine Multiquip parts to help you get your equipment back online with confidence.

Key Features

• Genuine OEM Voltage Protection: — Manufactured to the original electrical specification for transient suppression, ensuring the varistor clamps voltage spikes at the correct threshold for these generator control systems.
• Direct Plug-In Replacement: — Matches the original terminal configuration and mounting footprint, allowing installation without modification to the control board or wiring harness.
• Broad Generator Fitment: — Compatible with a wide range of Multiquip super-silent and ultra-silent generator models including DCA36SPXU4F, DCA40SSKU4F, DCA45SSIU4F, DCA70SSJU4F, DCA70USI2, MQP56, and additional DCA series variants.
• Protects Critical Control Electronics: — A functioning ZNR varistor absorbs destructive voltage surges before they reach sensitive generator control components; a failed varistor leaves control boards and AVR circuits exposed to damaging transients.
• Electrical Safety Compliance: — Using the correct OEM-specified varistor maintains the generator's designed surge protection ratings, which is essential for safe operation of connected equipment and onboard electronics.

A ZNR varistor is a metal oxide varistor used in generator control and electrical circuits to suppress voltage spikes and transient surges. When a sudden surge occurs — from a load switch, lightning-induced transient, or grid fluctuation — the varistor absorbs the excess energy and clamps the voltage to a safe level, protecting downstream components such as the automatic voltage regulator and control board. When a varistor degrades or fails, those protective functions are lost, leaving sensitive electronics vulnerable to damage that can cause erratic generator output, control faults, or complete circuit failure.
