14D182K MOV Varistor 1800V

14D182K MOV varistor (V1mA ≈ 1800V), also known as VDR-14D182K, is designed for high voltage applications where strong surge protection and high energy absorption are required.

Unlike standard AC or DC protection MOVs, this model is typically used in specialized industrial environments and power systems where high transient energy events may occur.

Typical Use Case:

14D182K is widely used in industrial power equipment, high voltage control systems, surge protection devices (SPD), power distribution applications and specialized electronic systems requiring high voltage protection.

The 14mm disc structure ensures reliable energy absorption and maintains stable performance under repeated surge stress conditions.
