PTC Self-resettable fuses provide self-restoring overcurrent protection, while SMD fuses provide single-acting fusing protection.If a short circuit occurs, some applications requires physical disconnection in the circuit without requiring a circuit reset and continued operation.In this case, SMD fuses can be used.PTC Self-resettable fuses can be used in applications where the circuit is to be protected from overcurrent events and then continue to operate after the event has passed and after a power cycle.
High power fuses are industrial fuses designed in accordance with UL, VDE, and ISO8820 standards, which can withstand extreme ambient temperatures, high cycling, and low level fault current conditions.The rated interrupting current of high-power fuses is extremely high, providing reliable overcurrent and short-circuit protection.Various installation configurations are used to meet customer design requirements.Applications for these products include, but are not limited to, EV/HEV, battery management systems, power supplies, DC-DC converters, telecommunication systems, photovoltaic power systems, industrial controllers and charging stations.
