When selecting an Automatic Air Circuit Breaker (ACB) for industrial or commercial applications, it's crucial to consider a product that offers reliability and robust performance. The ACB in question is designed to meet demanding requirements with its impressive specifications tailored for high-capacity electrical systems.
This ACB accommodates a wide range of rated currents from 1280A to 3200A, making it versatile for various load conditions. Its rated impulse withstand voltage of 12 kV ensures resilience against transient overvoltages, while the rated insulation voltage stands at a solid 1000 VAC, providing safety and durability in harsh environments.
With a rated short-time withstand current of 85 kA and a breaking capacity of 100 kA, this circuit breaker is engineered for exceptional fault management. It can handle significant fault currents without compromising system integrity, ensuring continuity and protection across your operations.
The ACB operates efficiently within systems up to a rated voltage of 690 VAC. It features the Ekip Touch LSIG trip unit, which provides advanced protection functions—overload (L), short-circuit (S), instantaneous (I), and ground fault protection (G). This intelligent trip unit enhances operational safety by allowing precise adjustments according to specific application needs.
Power loss is minimized with this design at just 743 W, promoting energy efficiency even under heavy loads. The four-pole configuration supports balanced load distribution across phases—a critical factor in maintaining stability in three-phase systems.
Installation flexibility is supported by its horizontal rear spread terminal type, facilitating streamlined integration into existing setups or new installations without extensive modifications. This feature simplifies the connection process while ensuring reliable electrical contact.
Compliance with IEC 309 standards underscores the product's adherence to international quality benchmarks, assuring users of its dependability and performance consistency across different scenarios.
Finally, housed within an E4.2 frame size, this ACB combines compactness with power handling capability—ideal for space-constrained environments where every inch counts but performance cannot be compromised.
For engineers seeking a dependable solution that aligns with rigorous technical demands while offering straightforward installation and maintenance options, this Automatic ACB presents as an excellent choice.
