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

Product Description

General description The 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 a. 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 places
g. Pollution degree: Three grade
h. Installation type:III
i. Installation condition: The slant angle between the installation surface and the vertical surface is no more than 15°. Main technical parameter
