14D241K MOV Varistor 240V

14D241K MOV varistor (240V), also known as VDR-14D241K, is intended for DC and industrial systems operating at higher voltage levels where reliable surge protection is required.

Compared with 14D221K, this model provides increased voltage margin, making it suitable for applications around 220V–240V DC systems with improved stability under transient conditions.

Typical Use Case:

This device is commonly used in industrial power supplies, automation equipment, communication systems and embedded electronics to protect against switching surges, ESD and transient voltage spikes.

The 14mm disc structure offers strong surge handling capability and ensures stable performance over long-term operation.

Key Electrical Characteristics:

Varistor Voltage (1mA): 240V ±10%  

Maximum Continuous Voltage: 150VAC / 200VDC  

Maximum Clamping Voltage: approx. 395V  

Peak Surge Current (8/20μs): 4.5kA  

Maximum Energy (2ms): 190J  

Capacitance (1kHz): approx. 950pF  

Application Focus:

DC power systems (220V–240V)
