When selecting an Automatic Air Circuit Breaker (ACB) for your industrial or commercial application, it's crucial to consider a product that balances performance with reliability. This particular ACB model is designed to meet the demanding requirements of modern electrical systems, making it an ideal choice for professionals seeking dependable circuit protection.
The ACB boasts a robust rated current range between 320 and 800 amperes, providing flexibility across various applications. It operates efficiently within a rated voltage of up to 690 VAC, ensuring compatibility with standard power systems. The device's ability to withstand impulse voltages of up to 12 kV further enhances its suitability for environments where high voltage spikes are anticipated.
Safety and durability are paramount in electrical installations, and this ACB excels in these areas. With a rated short time withstand current of 50 kA and a breaking capacity of 66 kA, it is engineered to handle significant fault conditions without compromising system integrity. These specifications underscore the breaker's capability to interrupt fault currents effectively while maintaining operational safety.
Equipped with the Ekip Touch LSIG trip unit, this breaker offers advanced protection features including long-time (L), short-time (S), instantaneous (I), and ground fault (G) protection functions. This comprehensive suite ensures precise tripping characteristics tailored to specific load requirements and enhances overall system protection.
The frame size E1.2 accommodates diverse installation needs while optimizing space utilization within switchgear assemblies. Additionally, the horizontal rear spread terminal type facilitates straightforward connections during installation or maintenance processes.
In terms of efficiency, the breaker maintains power loss at approximately 100 watts—a testament to its energy-conscious design that minimizes heat generation during operation. Compliance with IEC 309 standards guarantees adherence to international safety regulations and quality benchmarks.
With four poles included in its construction, this ACB supports balanced three-phase loads alongside neutral conductors if needed—enhancing versatility across different electrical configurations.
Whether you're upgrading existing infrastructure or implementing new projects requiring reliable circuit interruption capabilities, this automatic ACB provides a solid foundation backed by rigorous engineering standards suitable for Australian technical audiences who value factual performance data over promotional rhetoric.
