Generating electricity from solar energy is an extremely reliable process – as long as it’s properly protected! Mersen offers a trusted range of electrical protection solutions that help protect your solar power investment including fuses and fuse holders. Thanks to Mersen’s innovative HelioProtection® product line, faulty circuits are safely isolated and system longevity and reliability are increased, allowing for continuous generations of clean and efficient power.

Semiconductor Protection Fuses

Semiconductor protection fuses are used to protect against overcurrent conditions in power electronic equipment. They are specifically designed to reduce the I2t, peak let-through current, and arc voltages during a fault condition.

Mersen affords OEM designers and equipment-maintenance personnel a comprehensive line of Form 101 high-speed fuses with ratings from 130 to 1500 VAC. Plus, Square Body North American and European-Dimension high-speed fuses in 690/700 and 1250/ 1300V ratings (four sizes of each). Plus, compatible fuse blocks and accessories such as blown-fuse indicators, Trigger® switch actuators, and add-on switches.

Railway And Traction Power Converter Protection

Mersen DC high-performance power fuses were developed to provide superior protection for railway power circuits. They have lower I2t to minimize damage to components in case of short circuits and have lower watts loss and longer life.
