LCRR14D Series

Surge Suppression Varistor for Mid-to-High Energy Protection (K / KJ Series)

The MOV 14D Series Metal Oxide Varistors (including K and KJ types) are designed for robust surge suppression in industrial power supplies, communication systems, and power distribution networks. Compared with 10D, the 14D offers higher surge current capability and energy absorption, making it suitable for grid-level AC lines, motor control units, and industrial automation equipment. The KJ version features reinforced leads for higher mechanical and surge durability. Available in a wide voltage range from 180V to 820V.

MOV 14D Series is ideal for surge protection in the following systems:

  • Motor controllers, inverters, and industrial power supplies
  • Smart home AC bus protection
  • Telecom base stations and network input circuits
  • Smart metering and grid monitoring devices
  • High-power commercial LED drivers
  • AC line filters, lightning protection modules, and industrial control boards
