Boasting superior functional life performance due to their unique polymer formulation, Bel's new resettable fuses help protect against overcurrent surges and overtemperature faults by limiting the flow of dangerously high current during fault conditions. The PTC devices do not require replacement after a fault event as they reset themselves, allowing the circuit to resume normal operating conditions once the power is removed. This resettable functionality makes them the preferred alternative to traditional fuses and fusible links as their employment enables manufacturers to reduce repair, service, and warranty costs. Further, The RoHS-6 compliant resettable fuses are engineered to assist equipment in complying with telecom specifications including UL 60950, FCC Part 68, and Telcordia GR-1089.
