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 its rated current ranging from 1600 to 4000 A, making it suitable for a variety of demanding environments.
Designed to handle high voltage scenarios, this ACB boasts a rated impulse withstand voltage of 12 kV and an insulation voltage of 1000 VAC. It ensures safety and reliability even in challenging conditions, thanks to its impressive short-time withstand current rating of 66 kA.
The breaker operates efficiently at a rated voltage of 690 VAC, which aligns well with many industrial power systems. Its trip unit, the Ekip Touch LSIG, provides advanced protection features including overload (L), short circuit (S), instantaneous (I), and ground fault (G) protection. This makes it versatile for safeguarding electrical circuits against various faults.
One notable aspect is its power loss rating at 900 W—an important factor when considering energy efficiency in large-scale operations. The device includes four poles, providing comprehensive coverage for three-phase systems plus neutral.
Breaking capacity is another critical parameter where this ACB excels with a capacity of up to 66 kA. This ensures that the breaker can interrupt fault currents effectively without compromising system integrity or safety.
The frame size E4.2 indicates its compatibility within certain enclosure dimensions while maintaining structural strength and durability. Moreover, the horizontal rear spread terminal type facilitates easier installation in spaces where rear connections are preferable.
Compliant with IEC standards specifically IEC 309, this product adheres to international benchmarks for safety and performance—a vital consideration for engineers seeking products that meet rigorous quality criteria.
In summary, this Automatic ACB combines high-rated currents with substantial breaking capacities and advanced protective features via its Ekip Touch LSIG trip unit. It's designed to endure significant electrical stresses while minimizing power loss—a testament to both efficiency and reliability in demanding settings.
