Product type
Air circuit breakers (ACBs) are electrical devices used to protect electrical circuits from overloads and short circuits. They operate by interrupting the flow of electricity when a fault is detected, thus preventing damage to equipment and ensuring safety. ACBs are typically constructed with a combination of metal and insulating materials, and they utilize air as the medium for arc extinction during operation. This makes them suitable for high-voltage applications.
| Rated current | Up to 6,300 A |
| Voltage rating | Up to 1,000 V AC |
| Breaking capacity | Up to 100 kA |
| Mounting type | Fixed or draw-out |
| Standards compliance | IEC 60947-2, UL 489 |
When selecting an air circuit breaker, consider the rated current and voltage requirements of your application. It's important to specify the breaking capacity needed to handle potential fault currents. Additionally, check for compliance with relevant standards and certifications. Buyers should also consider the mounting type based on installation needs and the quantity required for their project.
