ASKW1 Air Circuit Breaker(ACB)

Product Overview

The ASKW1 series intelligent Air Circuit Breaker (ACB) is a cutting-edge solution engineered for low-voltage power distribution networks. Operating at AC 50Hz/60Hz with a rated voltage up to 690V and a rated current range of 630A to 6300A, it serves as a critical component for safe and efficient power distribution.

Designed to protect circuits and power equipment from overload, undervoltage, short-circuit, and single-phase grounding faults, the ASKW1 ACB integrates advanced intelligent protection and isolation functions. Its precise selective protection minimizes unnecessary power outages, significantly enhancing overall power supply reliability—a key advantage for industrial and commercial applications.

Equipped with an H-type controller featuring an open communication interface, the ASKW1 enables remote measurement, signaling, control, and adjustment. This compatibility with automated systems makes it ideal for modern smart grids and centralized control setups. The product complies with the IEC60947-2 standard, ensuring global safety and performance benchmarks.

Features

Innovative Closing Failure Protection Mechanism

A proprietary technology with a software registration certificate and national invention patent, this feature boosts operational reliability. Powered by a high-precision MCU microprocessor with millisecond-level response speed and strong anti-interference capability, it acts as a bypass unit without disrupting the main switch’s operation—reducing downtime and enhancing system stability.

Foreign Object Prevention Isolation Mesh

The ASKW1 ACB incorporates a metal perforated isolation mesh in its busbar cooling grilles. This design effectively blocks foreign objects from entering the breaker while maintaining optimal heat dissipation. It not only elevates operational safety but also meets stringent high-level protection standards, making it suitable for harsh environments.

Drawer Base Position Feedback Terminal

Equipped with dedicated position status feedback terminals, the ASKW1 relays the drawer base’s disconnected, test, and connected positions to intelligent backend systems. Installed on the product’s side without occupying auxiliary contact terminal blocks, this feature aligns with IoT requirements for low-voltage distribution equipment, supporting smart monitoring and remote management.

High-Performance Arc Extinguishing Chamber

Crafted from specialized insulating materials and optimized using computer-simulated arc-splitting grid angles, the arc extinguishing chamber ensures rapid arc extinction and dissipation upon entry—creating a zero arc-flash zone. Housed within an insulating base, it enhances mechanical strength, preventing rupture during high-current short circuits and maximizing safety.
