About this product
A 10D241K metal oxide varistor (MOV) that protects circuits against voltage surges and transients, such as those on mains-powered equipment. The 241 code indicates a nominal varistor voltage of about 240 V, and the K suffix denotes ±10% tolerance. It clamps excess voltage and diverts surge energy away from sensitive electronics.

Frequently asked questions
How is a MOV connected in a circuit?
A MOV is connected in parallel with the line or supply rail it protects, so it stays off during normal operation and conducts during a surge. Connect it between the live and neutral conductors or between the supply and ground, as your design requires.
Can I connect it directly to 220 V or 230 V mains?
Check the maximum continuous operating voltage (MCOV) in the datasheet before doing so. A 241-class varistor has a continuous AC rating well below its nominal voltage, so do not connect it to mains without confirming its rating.
