FUSECOMP CC
Electrical Component in Sandton

Most of above fuses are also available as high speed types for the protection of semiconductor devices. We provide advice on which accessories will work best with our products and supply all the correct components. Fusecomp stocks a wide range of fuses and can supply any type irrespective of brand. Due to our extensive knowledge of fuses we can offer alternatives to obsolete or rare Fuse types, and respecify if required. Our circuit protection solutions comply with major international standards: BS, IEC, DIN and UL. CSA the manufacturing operations of our suppliers have earned ISO9000 certification, ensuring the utmost quality across every product. Ampere The measurement of intensity of rate of flow of electrons in an electric circuit.One ampere is the amount of current that will flow through a resistance of one ohm under a pressure of one volt. Ampere Rating The current carrying capacity of a fuse. Arching Time The amount of time from the instant the fuse link has melted until the overcurrent is interrupted, or cleared. Clearing time is the total of the melting time and the arcing time. Current Limitation A fuse operation relating to short circuits only. When a fuse operates in its current limiting range, it will clear a short circuit in less than 1/2 cycle. Also, it will limit the instantaneous peak let-thru current to a value substantially less than that obtainable in the same circuit if that fuse were replaced with a solid conductor of equal impedance. Fast Acting Fuse A fuse which opens on overload and short circuits very quickly.This type of fuse is not designed to withstand temporary overload currents associated with some electrical loads. High Speed Fuses Fuses with no intentional time-delay in the overload range and designed to open as quickly as possible in the short circuit range. An ohm is the amount of resistance that will allow one ampere to flow under a pressure of one volt. Overcurrent A condition which exists on an electrical circuit when the normal load current is exceeded. Overload Can be classified as an overcurrent which exceeds the normal full load current of a circuit. Resistive Load An electrical which is characteristic of not having any significant inrush current. When a resistive load is nergized, the current rises instantly to its staedy state value, without first rising to a higher value. (root-mean-square) value of any periodic current is equal to the value of the direct current which, flowing through a resistance, produces the same heating effect in the resistance as the periodic current does. Short Circuit An overcurrent which exceeds the normal full load current of a circuit by a factor many times (tens,hundreds,or thousands greater). Time-Delay-Fuse A fuse with a built in delay that allows temporary and harmless inrush currents to pass without opening, but is so designed to open on sustained overloads and short circuits. Voltage Rating The maximum open circuit voltage in which a fuse can be used, yet safely interrupt an overcurrent. Exceeding the voltage rating of a fuse impairs its ability to clear an overload or short circuit safely.
