The Automatic Air Circuit Breaker (ACB) is a robust solution designed for industrial and commercial applications, offering reliable protection and control of electrical circuits. This model is engineered to handle demanding environments with a rated current range from 320 to 800 A, ensuring it meets the needs of various installations.
One of the standout features of this ACB is its impressive rated impulse withstand voltage of 12 kV, providing excellent protection against transient overvoltages. Coupled with a rated insulation voltage of 1000 VAC, this breaker ensures high safety standards are maintained across your electrical systems.
With a rated short time withstand current capacity of 50 kA and a breaking capacity of 66 kA, this device can manage significant fault conditions without compromising system integrity. The rated operational voltage stands at 690 VAC, making it suitable for medium-voltage applications commonly found in industrial settings.
The Ekip Touch LSIG trip unit integrated into this ACB offers advanced functionality for precise protection settings. This includes long-time (L), short-time (S), instantaneous (I), and ground fault (G) protections that enhance system reliability and safety by quickly responding to abnormal conditions.
This model also features four poles, accommodating balanced power distribution while minimizing phase imbalances in multi-phase systems. Designed with an E1.2 frame size, it provides compactness without sacrificing performance or durability.
For ease of installation and maintenance, the terminal type employed here is horizontal rear spread. This design not only simplifies connection but also optimizes space within switchgear assemblies—a critical factor in modern electrical infrastructure planning.
Power loss is an important consideration in any circuit breaker selection process; this unit maintains efficiency with a power loss rating capped at just 100 W under full load conditions. Such efficiency contributes to reduced operational costs over the lifespan of the equipment.
Compliance with IEC 309 standards underscores its quality assurance credentials—ensuring adherence to international norms for safety and performance which are crucial for peace-of-mind operation in diverse environments across Australia’s varied industrial landscape.
In summary, if you're seeking an automatic ACB that combines high-performance capabilities with efficient design principles tailored for demanding applications—this product warrants serious consideration as part of your electrical infrastructure strategy.
