From the shop's description

Metal Oxide Varistor 240V 6.5KA DISC 20mm 20D241K The Metal Oxide Varistor 240V 6.5KA DISC 20mm 20D241K is a high-performance surge protection device using zinc-oxide ceramic technology. Designed for fast and reliable clamping of voltage transients (e.g., lightning, switching spikes), this radial, 20 mm disc component features a nominal varistor voltage of 240 V and can safely conduct peak surges up to 6.5 kA (8/20 µs). Its bidirectional design and compact form factor make it ideal for protecting power supplies, telecom equipment, and consumer electronics. Features High-voltage surge protection up to 6.5 kA (8/20 µs). Nominal varistor voltage of 240 V with ±10 % tolerance (216 V–264 V range). Compact 20 mm disc design in through-hole format. Bidirectional operation for AC and DC transient clamping. Fast response time for efficient suppression of voltage spikes. RoHS compliant and UL-1449 recognized for safety. High energy absorption capability for reliable transient protection.
