3200 Amp Acb Air Blast Ckt Breaker

The 3200 amp acb air blast ckt breaker is as a core protective device in low voltage distribution systems, which demonstrates broad applicability across industrial, commercial, and infrastructure sectors. It benefits from the excellent performance parameters and modular design of the 3200 amp acb air blast ckt breaker.

The feature can be showed as the below:

1. Electrical Performance

The acb air blast ckt breaker has a rated current of 3200A and is suitable for three phase AC 50 Hz networks with a rated operating voltage of up to 690V. Its breaking capacity ranges from 65 kA to 100 kA, of which the air circuit breaker can effectively handle short circuit fault currents. Equipped with an intelligent trip unit, it provides four stage protection including long time delay, short time delay, instantaneous, and optional ground fault, with a protection threshold accuracy of ±5%.

2. Intelligent Monitoring System

Each 3200 amp acb air blast ckt breaker could customize a intelligent communication module which supports Modbus-RTU or Profibus-DP protocols. It can support real time monitoring of over 20 parameters such as current, voltage, and power factor. Fault waveforms and operational data can be analyzed via the LED display panel or through PC based management software.

Product FAQ:

Q: How fast does the 3200 amp acb air blast ckt breaker respond to a fault?

A: The 3200 amp acb air blast ckt breaker can interrupt fault currents within milliseconds, to minimize equipment damage and reduce downtime in critical systems.

Q: How often does a 3200 amp acb air blast ckt breaker need to have a maintenance?

A: the preventive maintenance schedule of a 3200 amp acb air blast ckt breaker can be showed as the below:

1. Mechanical Operation Test: Perform every 500 operations or every 12 months, whichever comes first.

2. Contact Resistance Test: Conduct every 3 years or after a short-circuit interruption.

3. Insulation Test: In environments with relative humidity above 85%, carry out every 6 months.

Q: What installation conditions should be considered?

A: the installation conditions of 3200 amp acb air blast ckt breakers are showed as the below:

1. The ambient air temperature shall not be higher than +40℃ and not lower than -5℃. The daily average temperature can not exceed +35℃.

2. The installation site shall be at an altitude of 2000 meters or below. Otherwise, the breaking capacity could drop down 1% for each 100 meter rises.

3. The atmospheric conditions is at an ambient temperature of +40℃. the relative humidity shall not exceed 50%. Meanwhile, at lower temperatures, higher humidity levels are permissible. During the most humid month, the monthly average minimum temperature does not exceed +25℃, and the monthly average maximum relative humidity does not exceed 90%, while allowing for condensation on the product surface due to temperature fluctuations.
