H01H77/107 - CPC Classification

Classification description:

Protective overload circuit-breaking switches operated by excess current and requiring separate action for resetting in which the excess current itself provides the energy for opening the contacts, and having a separate reset mechanism with electrodynamic opening characterised by the blow-off force generating means, e.g. current loops
