Product Description

ARW1 Highlights
  • Several components work together in an ACB. One of the main features is a blast valve. When the arcing contacts separate and the arc forms, the blast valve opens arc chutes. Pressurized air pushes through the arc, disconnecting it from the contacts.

  • The pressurized air pushes the arc towards arcing probes and rings. These are conductive elements that help to move the arc away from the contacts. As the arcing contacts get farther apart, the arcing probes and coils get closer together, allowing them to attract the arc.

  • The arc is moved into the chutes toward an arcing electrode. Eventually, the arc is pushed through the chutes and stretched until it is completely eliminated.

Frequently Asked Questions

What is the function of the blast valve in an ACB?

The blast valve is a key feature that opens the arc chutes when the arcing contacts separate and an arc forms. It allows pressurized air to push through and disconnect the arc from the contacts.

How does pressurized air assist in extinguishing the arc?

Pressurized air pushes the electrical arc away from the contacts and directs it toward conductive elements like arcing probes and rings.

What role do arcing probes and rings play?

Arcing probes and rings act as conductive elements. As the arcing contacts move farther apart, the probes and coils get closer together to attract and redirect the arc.

Where is the arc finally eliminated?

The arc is directed into the chutes toward an arcing electrode, where it is stretched until it is completely extinguished.

What happens when the arcing contacts separate?

When the contacts separate, an arc forms, triggering the blast valve to open the arc chutes and initiate the pressurized air flow.

How are MCCB parts and assembly processes structured?

The processing workflow relies on designated automatic assembling lines, specialized metal stamping offices, and structured parts processing systems to ensure optimal operational reliability.
