What is difinition of HIGH RESISTANCE FAULT and LOW
RESISTANCE FAULT?
Answer Posted / bryan
A high resistance fault is a fault that causes an over
current in the system but would not cause excessive heating
unless no action is taken for an extended period. A Low
resistance fault occurs and cause an output under voltage
situation and can lead to damage of the system if immediate
action is not taken to cut off the power stream.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?
