Fuses and Circuit Breakers

For additional circuit protection, Marsh offers a wide selection of EMI/RFI filter products designed to eliminate or control interference and noise in all stages of your product.

Our manufacturers also offer custom testing for your unique application.


For overvoltage and overcurrent protection devices, Marsh offers a wide range of products to choose from. For overvoltage applications, we offer a variety of varistors, TVS diodes, thyristors and gas plasma arrestors. Overcurrent protection devices include positive temperature coefficient devices (PTCs) and fuses. If your circuit protection application requires sub-assembly, wire leads with termination, or any other sub-assembly needs, our MarVac Assemblies division can build it per your drawings and specifications.
