When selecting a motor-operated air circuit breaker (ACB) for your industrial or commercial needs, understanding the technical specifications is crucial. The ACB in focus here offers a robust solution with its comprehensive set of features designed to handle demanding electrical environments.
This particular ACB supports a rated current range from 500 to 1250 A, making it versatile enough to accommodate various operational requirements. With a rated impulse withstand voltage of 12 kV and an insulation voltage of 1000 VAC, it ensures reliable performance even under high-voltage conditions.
One of the critical factors when choosing an ACB is its ability to withstand short circuits. This model boasts a rated short-time withstand current of 50 kA, providing strong protection against potential electrical faults. Furthermore, it has been engineered with a breaking capacity of 66 kA, ensuring efficient interruption capability during fault conditions.
The unit operates at a standard rated voltage of 690 VAC and includes an advanced Ekip Touch LSIG trip unit. This feature allows for precise monitoring and control over long-time, short-time, instantaneous, and ground fault protection settings—essential for maintaining system integrity and safety.
Designed with four poles and featuring an E1.2 frame size, this ACB fits seamlessly into various installations while optimizing space utilization. The horizontal rear spread terminal type further enhances installation flexibility by allowing easier connections in constrained spaces.
Power loss is often an overlooked aspect but remains significant in terms of efficiency. This breaker’s power loss stands at 244 W—a reasonable figure that balances performance with energy consumption considerations.
For those concerned about compliance and quality assurance, this product adheres to IEC 309 standards and approvals—a testament to its reliability across international benchmarks.
In summary, this motor-operated ACB combines essential features such as high breaking capacity, extensive current range adaptability, advanced trip technology, and compliance with global standards—making it well-suited for diverse electrical applications where reliability is paramount.
