A circuit breaker system is provided; the circuit breaker system comprises of a transformer, a capacitor, a pulse generator, a EBWF fuse and a VCB, the circuit breaker system can interrupt rated load current, overload current, surge load current and short-circuit load current within 100 microseconds. The on-state voltage drop of the circuit breaker system is below 0.1V. The circuit breaker system interrupts load current by injecting a non-resonant pulse current to reduce the current between the contacts of the VCB, and circuit breaker system interrupts higher load current by detonating the EBWF fuse to force an open-circuit. The EBWF fuse comprises a detonator in the low terminal and a contacting bellows in the upper terminal. The EBWF fuse can be engaged and dis-engaged by a fuse holder system.

An electrical device assembly and method to attach an isolated single stud fuse assembly to an electrical device are disclosed. The electrical device assembly consists of multiple studs, one or more of which is replaced with the isolated single stud fuse. A conductive copper landing zone receives an electrically isolated steel stud. When the landing pad assembly is orbital riveted into a plastic housing of the electrical device, the stud is locked into the housing permanently. Electrical devices such as disconnect switches and power distribution modules, both of which include multiple studs, are good candidates for being adapted with the single stud fuse assembly.

A thermal fuse may comprise an electrode and a conductor separated by a phase change material.
