In the realm of industrial and commercial electrical systems, selecting the right Automatic Air Circuit Breaker (ACB) is crucial for ensuring safety and reliability. This particular ACB model stands out with its robust specifications designed to meet demanding operational needs.
With a rated current range between 1600 to 4000 A, this ACB provides flexibility for various applications, accommodating both medium and high-capacity requirements. It operates efficiently under a rated voltage of 690 VAC, making it suitable for extensive industrial setups. The circuit breaker’s rated insulation voltage of 1000 VAC ensures safe isolation from electrical faults, while the rated impulse withstand voltage of 12 kV offers protection against transient over-voltages.
Safety is further enhanced by its impressive breaking capacity of 100 kA, which ensures that even in extreme fault conditions, the system can handle sudden surges without compromising performance. The rated short-time withstand current stands at an admirable 85 kA, providing resilience against temporary overloads or faults.
Equipped with the advanced Ekip Touch LSIG trip unit, this ACB offers precise control over long-time, short-time, instantaneous and ground fault protections. Such comprehensive functionality aids in minimizing downtime and maintaining operational continuity.
The power loss rating of this model is measured at 900 W—an important consideration for energy efficiency in large-scale installations where reducing unnecessary power dissipation translates into cost savings over time.
This model features a horizontal rear spread terminal type across its three poles configuration—ideal for streamlined integration into existing switchgear assemblies without requiring substantial modifications. Its frame size E4.2 accommodates significant thermal expansion and mechanical stress during operation.
Compliant with IEC 309 standards and approvals, users can be assured that this product meets international benchmarks for quality and safety—a critical factor when integrating components into complex electrical networks.
For professionals evaluating their next investment in circuit protection technology within Australia’s rigorous technical landscape, these specifications provide a clear picture of performance capabilities tailored to demanding environments.
