Motor: 12v AMP usage: 1.2amp Watt: 12x1.2=14.4W
L5 indicates the configuration and the 30 is the maximum current, in this case 30 amps.
The 40 amp motor probably produces double the horsepower of the 22 amp motor.
That is 10 amp wire.
Sizing circuit breakers for motors falls into a different category. Because of the inrush of current when the motor is in the stopped position, the breaker has to be sized to allow for this. Breakers usually are 250% of the nameplate full load amp rating. The wires that feed the motor are sized to 125% of the full load amps of the motor.
Assuming the wiring is sized for 12 amps, you can replace your fuse with any 12 amp fuse or smaller and with a voltage rating at or above what you expect to connect to it. The amp rating protects the wire, so you cannot go above what the wire can handle. The voltage rating is the max voltage that it can safely protect, so you cannot use a fuse with a lower voltage rating than you expect to connect to.
You need to instal the same size and amp rating as you removed.You need to instal the same size and amp rating as you removed.
This is a voltage drop question. A voltage must be stated to answer this question.
3Amp
No. A 6 amp switch is rated at 6 amps. A 12 amp motor will melt the contacts in the switch mechanism.
