RS PRO Ultra Rapid (FF) HBC – Ceramic Cartridge Fuses 5x20mm
RS PRO range of miniature ceramic cartridge fuses 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 fuse has blown it will need replacing in order to make the circuit complete and allow the flow of current.
Fuses are less expensive and react faster than a circuit breaker. However circuit breakers can be reset after they trip but a fuse will have to be replaced once it blows.
RS PRO cartridge fuse 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 fuses are a relatively cheap way of protecting electrical equipment from short circuits and overcurrent and can be used 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 fuse holder.
What Speed is it?
These particular fuses are (FF) ultra-rapid which means it is a fast acting fuse. FF fuses are good for semiconductor protection in devices like thyristors, diodes and transistors.
What are fuses used for?
• For the protection of components and equipment from costly damage caused 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 fuse can safely handle without exploding or rupturing. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit. This particular fuse is HBC (High Breaking Capacity).
