Mersen offers a comprehensive line of High Speed fuses optimally designed for protection of power electronics and power circuits.

Semiconductor protection fuse

Railway and traction power converter protection

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 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.
