Overload protection

Is it standard practise to fit 2 devices for overload protection, in motor control panels i.e. fuse for short circuit and electronic/thermal for overloads ?

  • The other feature of this is that the short circuit protection (often a fuse) must be at the supply end of the circuit but the overload protection, i.e. the thermal overload, can be anywhere and is often built into a box beside the motor.
