D45 Series MOV Block for Distribution Arrester

The D45 Series MOV for Distribution Arrester is a reliable, cost-efficient surge protection device designed to protect electrical and electronic equipment from surge-induced transient over-voltage. This series of metal oxide varistors are specifically designed for use in 10kV heavy load surge arresters, and provide reliable protection against high-energy transient surges. The MOVs are designed to be robust and long-lasting, and feature a high-temperature rated case and a wide operating temperature range to ensure the highest levels of performance and safety.
