Movable contact-holder carriage and electrical switchgear provided with such a carriage

摘要

The carriage (8) has a housing (80) for receiving a moving contact (5) associated with a return mechanism that is in the form of a compression spring, where the carriage is to be coupled with an actuator mechanism pertaining to an electrical cut-off device. An insulating support (81) comprises the housing, and a supporting structure (9) surrounds the insulating support to form a load-absorbing belt around the support. The supporting structure comprises a connecting part (91) intended for coupling the carriage with the actuator mechanism. An independent claim is also included for an electrical cut-off device.
