• RS PRO Ultra Rapid (FF) HBC – Ceramic Cartridge F***s 5x20mm. RS PRO range of miniature ceramic cartridge f***s which are ultra-rapid (FF) that operate at higher temperatures so are ideal to provide circuit protection to semiconductor devices. They are ideal for providing protection to devices or internal circuits from short circuits and overcurrent. They are deliberately weaker components which, when too much current is drawn, will blow. Once the f*** has blown it will need replacing in order to make the circuit complete and allow the flow of current. F***s are less expensive and react faster than a circuit breaker. However circuit breakers can be reset after they trip but a f*** will have to be replaced once it blows. RS PRO cartridge f*** packs are available in a range of current ratings with varying resistance values to suit all your requirements. This range is reliable for a broad range of applications. Features: Miniature ceramic cartridge FF Speed rated – very fast acting 5mm x 20mm cartridge size Very high interrupting rating High rated voltages Cylindrical shape Typical applications: Cartridge f***s are a relatively cheap way of protecting electrical equipment from short circuits and overcurrent and can be ***d to protect electrical appliances such as motors air-conditions, refrigerator, pumps etc. They can be found in the following areas: Industrial Commercial Home/Residential Automotive Additional Information What size is it? 5x20 mm is a standard cartridge size and it measures approximately 20 mm long by 5 mm in diameter. They are popular in board and panel protection and will fit a compatible 5x20 f*** holder. What Speed is it? These particular f***s are (FF) ultra-rapid which means it is a fast acting f***. FF f***s are good for semiconductor protection in devices like thyristors, diodes and transistors. What are f***s ***d for? For the protection of components and equipment from costly damage ca***d by over-current. To isolate sub-systems from the main system once a fault has appeared What is an over-current? It is a setting where a circuit experiences a current that is higher than the normal operating current. What is Breaking Capacity? Breaking capacity is the level of current that the f*** can safely handle without exploding or rupturing. The breaking capacity of your f*** should be greater than the fault current of your electronic circuit. This particular f*** is HBC (High Breaking Capacity).
