H01H77/102 - 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 special mounting of contact arm, allowing blow-off movement

Sub-classes:

H01H77/104 » {with a stable blow-off position} 21
H01H77/105 » {whereby the blow-off movement unlatches the contact from a contact holder} 3
