Varistors for residential, commercial and industrial applications

05-03-2021 | Littelfuse | Passives

Littelfuse has launched its LST Varistor series. Created with a proprietary thermally protected varistor technology (TMOV) developed by the company, this new varistor includes both a built-in thermal disconnect function and an electric arc shield. This combination provides further robust protection to avert catastrophic failure and fire hazard even under the extreme circumstances of abnormal overvoltage conditions or varistor end-of-life.

The series is particularly designed for Type 1 and Type 2 SPDs used in markets and applications, including residential, commercial, and industrial buildings; UPS; industrial motor control; renewable energy; and HVAC systems.

“The LST Varistor provides several advantages when compared to other technologies on the market,” said Boris Golubovic, vice president, Marketing and Strategy at Littelfuse. “By incorporating the LST in your latest design, you not only will benefit from its wide operating voltage range, high surge current rating, and compliment of options for microswitch, your SPD will also be more robust to meet the protection demands of your customer’s applications.”
