When it comes to ensuring the safety and reliability of your electrical systems, selecting the right Automatic Air Circuit Breaker (ACB) is crucial. This particular ACB is designed for industrial and commercial applications where performance and dependability are paramount. With a rated current range between 1280 A to 3200 A, this unit provides flexibility in handling varying power demands within complex electrical networks.
The breaker boasts a high breaking capacity of 100 kA, which ensures that it can effectively interrupt fault currents without compromising system integrity. Its rated short time withstand current of 85 kA further enhances its ability to handle transient conditions, making it suitable for environments where robust protection is required.
One of the standout features is its sophisticated Ekip Touch LSIG trip unit. This advanced technology offers precise control over the protection settings, allowing users to tailor the response characteristics to meet specific operational needs. The LSIG functionality covers long-time, short-time, instantaneous, and ground fault protection—ensuring comprehensive coverage against potential faults.
In terms of voltage ratings, this ACB operates efficiently at a rated voltage of up to 690 VAC with an impressive insulation rating of 1000 VAC. It also has a rated impulse withstand voltage capacity of 12 kV which adds another layer of security against surges and spikes that could otherwise damage sensitive equipment.
The frame size E4.2 indicates its suitability for larger installations without sacrificing space efficiency—a crucial consideration in many industrial setups. Furthermore, with horizontal rear spread terminals, integration into existing systems becomes more streamlined while maintaining optimal connectivity.
Power loss stands at 743 W which reflects efficient energy management—a key factor for operations looking to minimize waste and enhance overall system efficiency.
Compliant with IEC 309 standards and approvals ensures that this ACB meets rigorous international safety requirements—a testament to its quality engineering and reliable performance in demanding conditions.
Whether you're upgrading an existing system or designing a new installation from scratch, this Automatic ACB offers the durability and precision needed for modern electrical infrastructures.
