Fuse Terminology Of The Slow Blow Fuse 6T
| Terms | Definition |
| Rate/working current | Current rating is the normal operating current of the fuse. The
maximum continuous operating current of the circuit and the
influence of the ambient temperature (Normally is 25 C) are
important considerations when specifying the current rate. |
| Maximum current | It is related to the inrush current for various circuits, when we
select a correct fuse, we need to consider this and choose
“fast-acting” or “Time delay”product. |
| Voltage | The rated voltage is the maximum voltage at which a safe fault
current interrupt occurs. The maximum effective operating voltage
of the circuit is an important consideration when specifying the
rated voltage. Also, consider AC or DC circuits. Higher voltages
can be used in lower voltage circuits, but not vice versa. |
| I.R. or Breaking Capacity | The rated breaking capacity or interrupt rating is the
short-circuit current at which the fuse can blow (at the rated
voltage) without destruction or the maintenance or arcing or damage
the fuse case. The maximum possible fault current is an important
consideration when specifying a rated breaking capacity. |
| Size or Type | Depends on the requirements, normally it has SMD, Cartridge, radial
leaded or various size in high voltage fuses. |
| Short circuit | Over 500% to 700% of rated – current applies to the fuse. |
| Overloading | Over 100% rated-current apply to the fuse. |
| Inrush current | Inrush current, input surge current, or switch-on surge is the
maximal instantaneous input current drawn by an electrical device
when first turned on. |
| TC curve | Time – Current Curve. The fuse curves represent the cutoff value of
the prospective available short-circuits current under the given
circuit. |
