Electrical circuit protection

Our complete line of circuit protection products reflects a long tradition of creating solutions that enhance electrical safety, reliability, code compliance and efficient power distribution in alternative energy, commercial, industrial and mining operations.

Circuit breakers

Our low and medium-voltage circuit breakers provide premium protection for overheating wires, overloads and short circuits in residential, commercial, industrial and hazardous area applications.

Vacuum interrupters

We are a global leader in custom vacuum interrupter solutions, meeting both international and regional industry standards such as IEEE in the Americas, IEC in EMEA, and GB/DL in Asia-Pacific. Medium voltage circuit breakers and switchgear OEMs have successfully leveraged our customer vacuum interrupter solutions to create and sustain a differentiated market position.

Fuses and fuse holders

Bussmann series fuses play a major role in industrial or commercial facilities by providing reliable, maximum protection to power systems. Their physical size or rejection features prevent replacing a fuse with one from another fuse class. This helps ensure the correct replacement fuse is always installed and the voltage and interrupting ratings remain the same.
