800A Vacuum Contactor

Introduction:

The 800A vacuum contactor belongs to the JCZ7 series AC vacuum contactor produced by WUXI NANFANG ELECTRICAL APPARATUS CO., LTD. It is suitable for three-phase indoor electrical appliances with AC 50HZ-60HZ, rated working voltage 7.2KV, 12KV, rated working current 200A, 400A, 630A system.

JCZ7 series 800A vacuum contactor can be used for direct or long-distance load of electrical equipment such as motors, transformers, and capacitors that require frequent operations. The contactor is as class 6 as possible. In order to prevent the positive and negative contactors from closing at the same time, this series of AC vacuum contactors can be equipped with mechanical interlocking devices according to user requirements.

 

Characteristic:

1. Vacuum contactors use vacuum as the medium for arc interruption, unlike air or oil based contactors.

2. Compared with traditional contactors, vacuum contactors have longer mechanical and electrical life.

3. Unlike other contactors, they are maintenance-free and do not require regular servicing.

4. Compared with other types of contactors, they produce less noise and are more environmentally friendly.

5. Compact design, ideal for space-constrained applications. Operates even in harsh environments and extreme temperatures.

6. Higher short-circuit resistance, making them safer to use in high-voltage systems.
