Thermal protection for electrical circuits, comprises contact carrier, contact element with contact lug, supported on contact carrier and another contact element with another contact lug, which is supported on contact carrier

摘要

The thermal protection comprises a contact carrier (10) and a contact element (20) with a contact lug (50), supported on the contact carrier and another contact element (40) with another contact lug (60), which is supported on the contact carrier. The contact carrier moves between a contact-making and a contact-breaking position. The contact lugs are connected in a material connection in the contact-making position in the area of contact surfaces (52,62) by a layer (76), which melts at a preset trigger temperature.
