Product Description

ARW1

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 (FAQ)

How does the blast valve function inside the ARW1 Air Circuit Breaker?

The blast valve opens arc chutes when the arcing contacts separate. It allows pressurized air to surge through, stretching and cooling down the electrical arc until it is completely disconnected and extinguished.

What options are available for the rated current of the ARW1-2000 series?

The ARW1-2000 series circuit breaker has a frame size current rating of 2000A, and supports several rated current options (In) at 40℃, specifically: 630A, 800A, 1000A, 1250A, 1600A, and 2000A.

Can the ARW1-2000 series operate under different working voltages?

Yes, it operates under two main rated working voltages: AC400V (with an ultimate short-circuit breaking capacity of 80KA) and AC690V (with an ultimate short-circuit breaking capacity of 65KA).

What are the installation options for the ARW1 series circuit breaker?

The ARW1 series circuit breaker is designed for flexible integration and supports both fixed-type and draw-out type installation methods.

Does this circuit breaker series support isolation application?

Yes, the ARW1 series has isolation applicability, making it suitable and safe for isolating electrical sections during maintenance.

What are the physical dimensions and weight differences between 3P and 4P models?

For drawing dimensions, the 3P draw-out type typically has a dimension of 410×432×400 mm, whereas the 4P draw-out type spans 505×460×575 mm. The packaging and standard weights differ accordingly, with 3P weighing around 7200G (fixed variant at 4500G) and 4P weighing around 9000G (fixed variant at 5400G).
