How much tolerance can be allowed when setting the overload relay?

When setting an overload relay, a typical tolerance range is around 10-15% above the motor's full-load current rating. This allowance accounts for normal operational fluctuations and startup inrush currents while still providing protection against sustained overloads. It’s crucial to ensure that the settings are appropriate for the specific application and environment to prevent nuisance tripping or damage to the motor. Always refer to the manufacturer's guidelines for precise adjustments.
