Current Protection Component Test - Prodigit 3270 Series Operation Manual

5-8. Current protection component test

Current protection component include Fuse, Circuit breakers and a new PTC Resettable
Fuse etc.., its function is when the circuit current exceeds the design of the rated value, that
Is, if the load exceeds the design of the current capacity, the circuit will be disconnected, in
Order to avoid overheating, even fire. At the abnormal situation occurs it must be able to
Provide circuit break protection capability, while within the normal current range it must
Continue to provide current.
The current protection component has usually a product relationship of current and time,
That is, the greater the current through the current protection component, the shorter the
Reaction time to protect the circuit.
Due to this feature, the 3270 series AC & DC electronic load, in particular for the
Verification of current protection components, has developed a Fuse Test function to test
And verify such protection element with an electronic load of rated current and power.
