Product Information

Varistor Products Low to Medum Voltage, Radial Lead ZA Varistor Series The ZA Series of transient voltage surge suppressors are radial-lead varistors (MOVs) designed for use in the protection of low and mediumvoltage circuits and systems. Typical applications include motor control, telecom, automotive systems, solenoid, and power supply circuits to protect circuit board components and maintain data integrity. These devices are available in five model sizes: 5mm, 7mm, 10mm, 14mm and 20mm, and feature a wide VDC voltage range of 5.5V to 615V. See ZA Series Device Ratings and Specifications table for part number and brand information.
