Abstract

A low-voltage, high-rupture-capacity (hrc) fuse consists of a low- voltage, hrc fuse lower part (10) and a low-voltage, hrc fuse insert (22, 23), which is designed as an automatic circuit breaker. For this purpose, the commercial circuit breaker (23) is provided with connecting tabs (28) which lead to blade contacts (31) on the rear side of the circuit breaker (23). The blade contacts (31) are inserted in fork contacts (14, 15). A cover (60), which can be snapped onto the circuit breaker (23), is used for protection against touching. Furthermore, the cover (60) is provided with a coupling part (78), which is prepared for an extraction device for commercial low-voltage, hrc fuse inserts to be coupled on. <IMAGE>
