The transient voltage surge suppressor is a radial lead varistor (MOV) designed to protect medium and low voltage circuits and systems. Typical applications include motor control, telecommunications, solenoid valves, and power supply circuits to safeguard circuit board components and maintain data integrity. Five model sizes are available: 5mm, 7mm, 10mm, 14mm, and 20mm, with a DC voltage range from 5.5V to 615V.
