BS88 fuses and fusegear
Hybrid DC power relay
Mersen's Hybrid DC Power Relay is engineered to provide a high DC switching performance versus conventional mechanical DC power relay, switch and contactor. This power relay is hybrid technology with the capability of switching to both high voltage and high current especially for electrical vehicle applications.
Hybrid DC overcurrent protective device
Mersen's Hybrid DC Overcurrent Protective Device is composed of a fast acting pyro element, controlled by a gate current, plus a parallel clearing element. This protection meets custom requirements of a very fast operating time and a very high overload current.
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.
