Printed circuit fuse assembly

In an electrical device having an electrical circuit including a plurality of electrical components, an improved fuse assembly comprising:

• a current actuated first fuse having a predetermined current rating for protecting said electrical circuit, said first fuse accessible to the user of said electrical device to permit replacement thereof by said user;
• a current actuated second fuse connected in series with the first fuse and measuring the same current, having a predetermined current rating higher than said current rating of said first fuse for protecting said circuit in the event of misuse of said electrical device by said user caused by the bypass or improper replacement of said first fuse;
• said fuses connected in said circuit to interrupt power to said circuit upon burn-out of either of said fuses;
• and
• said first fuse interrupting power to said circuit in preference to said second fuse for all overload current conditions of said electrical device.

In an electrical device having an electrical circuit including a plurality of electrical components, an improved fuse assembly, comprising:

• first circuit interrupting means, for opening said circuit at a first predetermined current level to protect said circuit;
• second circuit interrupting means connected in series with the first circuit interrupting means and measuring the same current, for opening said circuit at a second predetermined current level, higher than said first predetermined level, for protecting said circuit in the event of misuse of said first circuit interrupting means by a user;
• said first circuit interrupting means opening said circuit in preference to said second circuit interrupting means for all overload current conditions of said electrical device, and
• said first circuit interrupting means easily replaceable or resettable by said user, said second circuit interrupting means less easily replaceable or resettable by said user than said first circuit interrupting means to provide a record of misuse of said first interrupting means.
