688 Fuses

Littelfuse 688 Fuses offer protection superior to that of circuit breakers, providing short-circuit and overload protection and ensuring long-term reliability for applications with high surge exposure levels. This device also reduce the level of nuisance fuse tripping caused by indirect lightning surges. Littelfuse 688 Fuses are optimized for protection of power distribution equipment used in wireless telecommunication base transceiver stations (BTS). This fuse can also replace the air circuit breaker currently used for short-circuit protection in the surge protection box of 48V telecom power systems.
