Description
Product Overview
The Littelfuse MOV 250V 320VDC 8mm V07E250 is engineered with a robust metal oxide semiconductor composition that provides fast response to transient voltage events. Each varistor measures 8mm in diameter, offering a compact footprint that fits easily into dense circuit layouts. With a voltage rating of 250V nominal and a clamping capability up to 320VDC, the device safeguards downstream components from spikes that could otherwise cause costly downtime. The pack of twelve units ensures you have sufficient inventory for multiple protection points across a system, reducing the need for frequent re‑ordering. Designed for industrial environments, the varistor meets stringent quality standards and is backed by Littelfuse’s reputation for reliability.
Usage
These varistors are ideal for protecting power supplies, motor drives, PLCs, and other critical industrial equipment where voltage transients are common. They perform well in harsh conditions, tolerating temperature extremes from -40°C to +125°C, making them suitable for outdoor installations, manufacturing floors, and automotive applications. Install the MOVs across the line and neutral or between line and ground to clamp surges before they reach sensitive circuitry. Their low leakage current ensures minimal impact on normal operation while delivering high energy absorption during fault conditions. Whether you are retrofitting an existing system or designing a new product, the 12‑piece pack provides flexibility for multiple protection zones.
