FAQ
What is the acb working principle?
An air circuit breaker (ACB) utilizes air as an arc-quenching medium to interrupt electrical flow during faults, preventing damage. It employs a high-resistance interruption method, rapidly increasing arc resistance by methods like cooling, lengthening, reducing cross-section, and splitting. ACBs, widely used in power systems and industrial settings, feature high sectional capability, compact structure, and excellent performance. They offer multiple protection functions, ensuring power line and equipment safety with built-in thermo- and magnetic tripping mechanisms for real-time monitoring and comprehensive protection.
What is the difference between acb and mccb？
The main differences between an Air Circuit Breaker (ACB) and a Molded Case Circuit Breaker (MCCB) are as follows:
Utilization Category: ACBs are category B devices, while MCCBs are category A devices.
Application: ACBs are typically used in high current applications such as power transmission lines and power distribution stations, while MCCBs are commonly used at the load side for switching and protection.
Voltage Rating: ACBs are suitable for voltages of up to 1140 volts, including power distribution lines and systems, whereas MCCBs are built for use in systems with voltages of 120V, 240V, and 380V up to 660V.
Tripping Thresholds: The tripping thresholds can be adjusted easily in the MCCB, making it favorable in different circuits over other circuit breakers. The tripping thresholds can also be adjusted in the ACB, but it is a bit more complex.
Operation: There is a thermal-magnetic operation in the MCCBs. In the previous MCCBs, there was only one operation which was generally magnetic. The ACB also has a thermal-magnetic operation.
In summary, ACBs are generally used in high current applications and for voltages up to 1140 volts, while MCCBs are commonly used at the load side for switching and protection and for systems with voltages of 120V, 240V, and 380V up to 660V.
How to perform circuit breaker troubleshooting of ACB？
Troubleshooting details for air circuit breakers (ACBs), covering common issues and possible causes, along with suggested solutions:
Breaker Is Not Closing:
Probable Cause: Undervoltage release not connected with supply.
Probable Solution: Give rated voltage to undervoltage release.
Breaker Is Not Tripping with Undervoltage or Shunt Release:
Probable Cause: Shunt release does not get supply.
Probable Solution: Check the control wiring of the shunt release and ensure that it gets supplied.
Breaker Is Not Tripping by Manual Trip Push Button:
Probable Cause: The trip latch of the mechanism spring is not in the proper position or is misplaced.
Probable Solution: Fix the spring correctly.
Breaker Is Not Closing Remotely:
Probable Cause: Closing coil is not getting supply.
Probable Solution: Check the control circuit and ensure that the coil gets supplied.
