When it comes to selecting a reliable Automatic Air Circuit Breaker (ACB) for industrial and commercial applications, understanding the technical specifications is crucial. This ACB offers robust performance with a rated current range of 1280-3200 A, making it suitable for various demanding environments. Its rated impulse withstand voltage of 12 kV ensures resilience against transient overvoltages, while the rated insulation voltage stands at an impressive 1000 VAC.
A key feature is its rated short-time withstand current of 85 kA, providing assurance in maintaining operational stability during short circuits. The breaker operates efficiently at a standard rated voltage of 690 VAC and boasts a breaking capacity of 100 kA, ensuring effective interruption of fault currents.
The trip unit integrated into this device is the Ekip Touch LSIG model, which provides advanced protection functions including long-time (L), short-time (S), instantaneous (I), and ground fault (G) protections. This comprehensive functionality helps in safeguarding electrical systems from potential damage due to overloads or faults.
Designed with four poles, this ACB accommodates balanced power distribution across phases. The frame size E4.2 indicates its compatibility within specific enclosure dimensions and mounting configurations. Furthermore, the horizontal rear spread terminal type facilitates easy integration into existing setups without requiring significant alterations.
In terms of energy efficiency, the power loss rating is measured at 743 W during operation—an important consideration for minimizing operational costs over time. Compliance with IEC 309 standards underscores its adherence to international safety and performance benchmarks.
