Silver/Copper/Tungsten Electrical Contacts – Circuit Breaker Contacts

Arcing contacts in breakers are designed to handle the electrical arcs that occur during the switching operation of the breaker. When a circuit breaker interrupts a current flow, an arc is formed between the contacts. This arc can cause significant damage to the contacts and hinder the proper functioning of the breaker.

To mitigate the effects of arcing, breakers are equipped with contact materials to handle and extinguish the arc efficiently. The contacts have a specific shape and design to withstand the heat and pressure generated by the arc.

Prioritize your effective solution with carefully designed arcing contacts for breakers and expertly manage electrical arcs during operation to optimize performance.

High quality arcing contacts are made from top-tier materials like copper-tungsten or silver-tungsten compounds, known for superior arc-extinguishing properties. Experience unparalleled performance that meets innovative technology, ensuring your circuit breakers’ efficiency and durability.


Arcing contacts for breakers are widely applied in various industries and end products. The components ensure the proper functioning and protection of electrical systems. They are ideally suited for usage in air circuit breakers, oil circuit breakers, Molded Circuit Breakers, and other electrical Protective Devices. Their presence is crucial to maintain safety, reliability, and efficiency systems in various applications.
