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 ?

Parents
  • Yes it is common practice, but not actually a requirement, a single device that protects against both overload and short circuit is permissible.
