With so many different types of overloads and their options, how do I choose the right protection for my motor?
The purpose of the overload is to protect the motor from overheating. Overheating can result from numerous reasons. The more advanced the overload, the more possibilities for overheating it caters for. Another distinction between overloads is the method by which they monitor the heat of the motor and their accuracy. The decision on which overload to use comes from considering a number of issues such as budget, the replacement cost of the motor should it fail, and the opportunity cost or downtime cost while the motor is out of action. Quite often the biggest contributor is the last one – the downtime cost. Simply put, the choice of overload is ‘horses for courses”. The bigger the dollars involved, the more sophisticated the motor protection should be. The Sprecher + Schuh range of overloads cater for all industry requirements.
