Product Description
General descriptionThe Mining Equipment 1.14kv 1000A 1250A High-Performance Vacuum Contactor is designed for use in AC 50Hz power networks with a main circuit rated voltage of 1140V. It is suitable for making, breaking, frequently starting, and controlling AC motors, and can be used to form a magnetic starter with a variety of protectors, including JDB electronic integrated protection, JR9 type over current protection devices, and the RC absorption device. This vacuum contactor is particularly well-suited for use in anti-explosion magnetic starters and large mineral lapping switch equipment.
The contactor conforms to GB/T 14048.4, IEC 60947-4-1, and JB/T 7122 standards, and its main performance indicators meet international levels. As a result, it is a reliable and high-performance option for those in need of a contactor, vacuum contactor, or LV vacuum contactor.Normal using conditions
