630A AC Contactors China Medium Voltage High Magnetic 12kv Vacuum Power Contactor

Product Description

1 Overview
JCZ5-12 series indoor AC high voltage vacuum contactor (referred to as contactor for short) is divided into two types: closing mechanical holding and electromagnetic holding. The contactor is suitable for three-phase AC 50HZ. The rated voltage is 12KV. The rated current is up to 630A In the power system, it is used for long-distance connection and disconnection of lines, control of high-voltage motors, transformers and capacitive loads and other electrical equipment, especially suitable for various frequent operation fields.
The contactor is small in size and light in weight. It adopts the popular international assembly structure of upper and lower arrangement, which is easy to use and maintain, and it is easy to form a complete set of FC circuit equipment.
