Auxiliary Contact Switch The Auxiliary Contact Switch is a switch used in electrical equipment to extend the signal transmission function, assisting in the condition detection of main circuit equipment and providing additional switching signals during signal transmission. It acts as an auxiliary device to the main switch, providing additional contact signals to meet complex electrical control and indication requirements. Used to feedback, control, protect or indicate the status of a system, especially in automation and monitoring systems, plays a vital role. The auxiliary switch consists of a set of normally open (NO) and normally closed (NC) contacts that are synchronized with the state of the main switchgear. When the main device is operating, the contact of the auxiliary switch will be opened or closed according to the operating state of the device, thereby transmitting the signal to the control system or indicating device.

VSG-12 type Indoor high voltage vacuum circuit breaker used spring to storage energy. The operating mechanism can be operated by two ways, by manual and electromotive operation, The characteristics is according with GB1984-2003 High Voltage AC Circuit Breaker, JB3855-1996 3.6-4.5KV Indoor AC High Voltage AC Circuit Breaker and IEC standard 62271-100:200162271-100:2001 High Voltage AC Circuit Breaker VSG-12 1250A Vacuum Circuit Breaker (VCB) is designed for medium voltage power distribution and protection applications. Built with advanced vacuum technology, the VSG series ensures reliable and safe operation in various industrial and commercial environments. As a withdrawable type circuit breaker, this VSG-12 1250A VCB breaker is ideal for applications requiring frequent switching and offers exceptional performance and durability.

The VSM-12 vacuum circuit breaker integrates a permanent magnet operating mechanism and a vacuum interrupter in a front-and-rear configuration. The breaker features a draw-out type design with a fixed arc-extinguishing column (solid sealing poles) and is designed for high reliability and performance in demanding electrical environments. The permanent magnet operating mechanism and the vacuum interrupter of the VSM-12M vacuum circuit breaker adopt front and rear arrangement. The main conductive circuit is a floor-standing structure. The upper and lower outlet seats and the vacuum interrupter are installed in an embedded pole Inside. The embedded pole is made of epoxy resin by APG process. This structure can prevent dust accumulation on the surface of the vacuum arcing chamber and prevent it from being damaged by external factors. It can ensure that the product still has good insulation performance in the humid and hot environment and serious pollution.

The Fixed Hinge for Electrical Panel is a critical component designed to ensure the secure and smooth operation of panel doors in electrical enclosures. This hinge is engineered from high-grade materials, typically stainless steel or heavy-duty alloy, to provide exceptional durability and resistance to corrosion, even in harsh industrial environments. The hinge's design allows for precise alignment of the panel door, ensuring a consistent and tight seal that protects internal components from dust, moisture, and other external contaminants.
