When it comes to selecting an Automatic Air Circuit Breaker (ACB) for your industrial or commercial needs, the balance between technical performance and reliability is key. This ACB offers a robust solution with its impressive specifications designed to handle demanding electrical environments.
With a rated current range of 1000-2500 A, this ACB is versatile enough to cater to various electrical load requirements, making it suitable for diverse applications in large-scale operations. The device operates effectively at a rated voltage of 690 VAC, ensuring compatibility with standard industrial power systems.
Safety and durability are paramount in circuit breakers, and this model excels with a rated impulse withstand voltage of 12 kV. This feature provides enhanced protection against transient overvoltages which can occur due to lightning strikes or switching surges. Additionally, the breaker boasts a rated insulation voltage of 1000 VAC, further underscoring its capacity to handle high-voltage applications safely.
The breaking capacity stands at an impressive 66 kA, meaning that this ACB can interrupt substantial fault currents without compromising on safety or performance. Coupled with its rated short-time withstand current also at 66 kA, it ensures resilience during short-circuit conditions by maintaining operational integrity.
An essential aspect of any circuit breaker is its trip unit; here we have the Ekip Touch LSIG trip unit. Known for precision and reliability, this unit provides advanced protection features including Long time (L), Short time (S), Instantaneous (I), and Ground fault (G) protections which are crucial for safeguarding equipment and ensuring continuity of service.
In terms of installation flexibility, the product's frame size is designated as E2.2 with horizontal rear spread terminals which simplify integration into existing switchgear setups while optimizing space usage.
Energy efficiency considerations are met with a power loss figure standing at 550 W—an important factor when calculating overall system efficiency and operating costs over time.
Designed in compliance with IEC 309 standards and approvals, this ACB adheres to international benchmarks for quality assurance and safety regulations providing peace of mind regarding its dependability in real-world scenarios.
This four-pole configuration allows comprehensive phase-to-phase as well as phase-to-neutral protection—a crucial requirement for balanced three-phase systems often used in industrial settings where uninterrupted service is critical.
Overall, whether you’re upgrading existing infrastructure or designing new installations from scratch, these specifications ensure that you have all bases covered when choosing an automatic air circuit breaker that aligns perfectly with your technical requirements without compromise.
