When considering an Automatic Air Circuit Breaker (ACB) for your industrial or commercial applications, the technical specifications are paramount. This ACB is designed to handle demanding environments with its robust and reliable features.
Starting with its rated current range, this ACB accommodates between 1000 to 2500 Amperes, making it versatile for various load requirements. It supports a rated voltage of up to 690 VAC, ensuring compatibility with standard industrial power systems. The rated insulation voltage stands at 1000 VAC, providing a strong barrier against electrical faults.
Safety and reliability are critical in any circuit breaker, and this unit meets those needs by adhering to IEC 309 standards. Its breaking capacity is set at an impressive 66 kA, which ensures that it can effectively interrupt fault currents without compromising system integrity.
The trip unit integrated into this ACB is the Ekip Touch LSIG model. This advanced technology offers precise protection by monitoring overcurrent conditions and responding swiftly to minimize potential damage. With a rated impulse withstand voltage of 12 kV, the breaker can endure transient over-voltages typically encountered during lightning strikes or switching surges.
Designed with practicality in mind, this ACB has a frame size of E2.2 and comes with horizontal rear spread terminals for easy integration into existing setups. The three-pole configuration allows for balanced distribution across phases while maintaining system stability during operation.
Power efficiency is also addressed; the power loss is kept at 550 W under normal operational conditions—an important consideration when evaluating long-term energy consumption and cost-effectiveness.
Lastly, its rated short time withstand current matches its breaking capacity at 66 kA—a testament to its durability under high-stress scenarios where sustained fault currents might occur before clearance actions take place.
This Automatic ACB combines essential safety features with performance efficiencies suitable for rigorous electrical environments—ideal for professionals seeking reliability without compromise in their installations.
