Circuit Breakers

Circuit Breakers are circuit protection devices used to interrupt current during overcurrent, short-circuit or fault conditions. Unlike one-time fuses, many circuit breakers can be reset after the fault is cleared, making them suitable for systems that require repeatable protection, maintenance convenience and reliable electrical safety.

This category includes thermal circuit breakers, magnetic circuit breakers, thermal-magnetic circuit breakers, resettable circuit breakers, panel mount circuit breakers and related overcurrent protection devices. These components are commonly selected based on current rating, voltage rating, trip characteristics, breaking capacity, reset type, mounting method, package style, safety approvals and application requirements.

TomatoElec supplies original Circuit Breakers from recognized manufacturers such as Littelfuse, Eaton, TE Connectivity, Schurter, Phoenix Contact, Schneider Electric, Siemens, Sensata and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
