4000A Sulphurized Contact Arm – Optimized for Reliable Electrical Transmission
The 4000A Sulphurized Contact Arm is crafted from high-conductivity materials and treated with advanced sulphurization to significantly improve both electrical conductivity and resistance to corrosion. This ensures that the contact arm can efficiently transmit electrical current with reduced resistance, thereby lowering energy loss and improving overall efficiency in circuit breaker systems.
Key Advantages of the 4000A Sulphurized Contact Arm
This contact arm's sulphurization treatment not only boosts its conductivity but also enhances its ability to withstand harsh industrial conditions, prolonging its service life. This makes it an ideal solution for environments where equipment is subject to frequent operations. Additionally, the contact arm's ability to minimize energy loss contributes to greater operational efficiency and long-term cost savings for your business.


The vulcanized contact arm is mainly used to improve the conductivity and corrosion resistance. The contact arm can improve its conductivity through vulcanization treatment, ensure that the current transmission in the circuit breaker is more efficient, reduce resistance, and thus reduce energy loss. It can also enhance the corrosion resistance of the contact arm so that it can better adapt to various harsh working environments and extend the service life of the equipment. Since the VS1 indoor vacuum circuit breaker is suitable for places with frequent operations, these characteristics of the vulcanized contact arm enable it to better meet this demand and ensure the stable operation of the equipment.
