When considering a reliable and robust solution for your industrial or commercial electrical systems, the non-automatic Air Circuit Breaker (ACB) with a rated current of 4000 A stands out as a strong contender. Designed to meet the rigorous demands of modern electrical infrastructure, this ACB is engineered for efficiency and safety.
Operating at a rated voltage of 690 VAC, it offers substantial capacity to handle high-power applications. Its rated insulation voltage of 1000 V ensures that the breaker can safely manage electrical isolation even under demanding conditions. Furthermore, with a rated impulse withstand voltage of 12 kV, this ACB is well-equipped to endure transient overvoltages without compromising performance.
The breaker features three poles, making it suitable for three-phase power distribution systems commonly used in industrial settings. The degree of protection is marked at IP30, providing adequate protection against solid objects larger than 2.5 mm while being mindful that it's not protected against water ingress.
In terms of dimensions, its compact design—425 mm in width and height and 383 mm in depth—allows for easy integration into existing panels or switchboards without requiring excessive space. Weighing in at 60 kg, it strikes a balance between sturdiness and manageability during installation or maintenance procedures.
From an efficiency perspective, the power loss is noted at 900 W. This figure indicates its energy consumption during operation which should be factored into overall system energy management plans but remains within reasonable limits given its capacity.
Compliance with IEC 309 standards underscores its adherence to international safety and performance benchmarks—a critical factor when selecting components for any project aiming for reliability and regulatory compliance.
This non-automatic ACB serves as an integral part of any high-capacity electrical distribution system where dependable operation is paramount. Its specifications make it suitable for various applications across industries ranging from manufacturing plants to large-scale commercial facilities where managing significant electrical loads efficiently and safely is crucial.
