Mining Equipment 1.14kv 1000A 1250A High-Performance Vacuum Contactor

 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 conditionsa. Environment temperature: -5ºC~+40ºC, and the average value is no more than +35ºC within 24 hours.b. Altitude: no more than 1000m.c. Atmospheric conditions: monthly highest humidity in the wettest month is no more than 90% and the monthly average minimum temperature shall be 25ºC. Condensation on the products due to temperature changes shall be considered.d. Impact vibration: The place is without extensive shaking, impact, and vibration.e. The place is without explosion hazards, enchant gas, and sleet.f. No rain and snow in placesg. Pollution degree: Three gradeh. Installation type:IIIi. Installation condition: The slant angle between the installation surface and the vertical surface is no more than 15°.Main technical parameter ItemUnitCKJ-5-1000~1250/1.14Main circuit rated voltagekV1.14Main circuit rated currentA10001250Main circuit making capacityA/100times6000Main circuit breaking capacityA/100times4500Limit breaking capacityA/3times5000Electrical life AC3times600,000Electrical life AC4times60,000Mechanical life timetimes1,000,000Rated operating frequency AC3times/h600Rated operating frequency AC4times/h120Short-time operating frequency(20s)times/h1000Clearance between open contactsmm2.8±0.1Over travelmm1.0±0.1 Packaging For Vacuum Circuit Breaker, pls click:  https://china-vacem.en.made-in-china.com/product-group/roqEnxmCTUYh/Vacuum-Circuit-Breaker-catalog-1.html International fairs Company show
