There are many types of overload protection these days and all are based on the FLA (full load amps) of the motor.

Does increasing the amp hours of a 36 volt battery system have the potiential to overload a motor?
No. Amp-hours is the measure of how long the battery can keep doing the job before it's exhausted. As long as the voltage of the battery remains the same, the motor doesn't know that anything has changed.
What is a heater overload?
overload heater is used to protect a large electric motor. If the overload heater get too hot from excessive current. its nomally-closed overload contacts wil open. interruptting the circiut of powe supply of motor
Will a motor shut down if the run capacitor fails?
If a motor is running when the cap fails it will probably continue to run at much higher amp draw and most likely shut down on thermal overload. It can start with a bad cap, but in my experience it most likey wont.
Does overload relay detect phase reversing of the 3 phase motor?
No, three phase motor overloads just monitor the motor's lines for an overload. Once detected the circuit holding the magnetic starter in will drop out and take the motor off line.
What is overload protection?
It is protection installed to protect, usually motors, from going beyond the amperage capacities that were set down by the manufacturer's specifications of the motor. As a motor loads up to its rated HP it will operate within the motors amperage range. More loading on the motor will increase the amperage draw to a point where the motor's winding will start to burn or short out due to insulation breakdown of the motor coils. Over load protection is a settable device that will limit the current to a specific value. The setting on the over current device is the motor's FLA (full load amps). If the motor amperage goes higher that the set point the overload protection, the overload protection contacts will open and drop the motor's magnetic contactor off line. In some cases this could be an annoyance but it does save the motor from destroying itself.
What size breaker is used for a 300 horsepower motor?
A breaker is based on the amount of current that the motor draws. This amperage should be taken off of the motors nameplate. In motors of a specific horsepower the amperage is proportional to the voltage the motor uses. Without the motors voltage this question can not be answered.
What is the conclusion of overheat protection of induction motor?
If the overload protection is set correctly to the motors full load amperage, any overloading of the motor will trip the protection and take the motor off line. Once the reason of the overload has been established and rectified, the overload protection is reset and the motor can be brought back on line.
Can you overload a channel on a amp?
Yes you can burn a channel on an amp. Which is do to a overload. Like a 2 ohm load on an amp that is not 2 ohm stable. Will burn out a channel or both channels.
A device with a overload protection used to control a motor is a?
A device with an overload protection used to control a motor is an Overload Relay.

Can you start 20kw motor on direct on line circuit?
No, the motor has to be connected to the line voltage through a set of fuses and then an electrical contactor. Also the motor must be thermally protected against overloads by using an overload block or heaters. This is to allow the motor contactor to drop out is a overload fault should occur.
What is the difference between a 40 amp and 22 amp motor?
The 40 amp motor probably produces double the horsepower of the 22 amp motor.
What is a heater overload?
overload heater is used to protect a large electric motor. If the overload heater get too hot from excessive current. its nomally-closed overload contacts wil open. interruptting the circiut of powe supply of motor
Describe the steps you take to troubleshoot a 3 phase 480 volt motor that continually trips the heaters?
Start by checking the motor current when the motor is running under load with a clamp on amp meter. If it is over nameplate rating, check and find out if the load the motor is driving is somehow dragging and creating more load that normal. 98% of the time it is the load seizing up that causes motors to trip. Drop the load off the motor and see if the motor runs under nameplate amperage. If it does that is good. Check for loose connection in the motor contactor and around the overload heater block. Check and make sure the overload heaters are set to the FLA of the motor. As a last resort megger the motor to make sure one of the phases has not grounded out.
Can you replace a 15 amp fuse in your car with a 20 amp fuse for a cigarette lighter It keeps blowing the 15 amp?
No, you could overload the wiring and start a fire.
How do you calculate 3 phase motor overload relay setting?
overload model no Ke-FKR4(D)
How moeller's overload relay works?
Moeller's overload relay works by monitoring the current flowing through a motor. If the current exceeds a set value for a period of time, the relay will trip and disconnect power to the motor, protecting it from damage due to overheating. This helps prevent the motor from drawing too much current for an extended period, which could be harmful.
