The 2000 Amp Intelligent Universal Air Circuit Breaker (ACB) is the cornerstone of modern low-voltage power distribution. Engineered for primary incoming and outgoing lines in heavy industrial and commercial grids, this breaker provides comprehensive protection against overloads, short circuits, and ground faults.

The Drawer Type (Withdrawable) design is specifically engineered for high-availability environments. It features a robust cradle that allows the breaker body to be racked in and out, facilitating rapid maintenance and visible isolation without disconnecting the main busbars. Equipped with a high-performance microprocessor-based intelligent trip unit, the breaker ensures perfect selective coordination, isolating only the faulted part of the system to maintain facility uptime.

• High Breaking Capacity (Icu/Ics): Rated for 65kA/80kA short-circuit interruption, protecting your infrastructure from the catastrophic mechanical and thermal stresses of massive electrical faults.

• Intelligent Micro-Processor Trip Unit: Features advanced digital protection with adjustable settings for LSI (Long-time, Short-time, Instantaneous) and Ground Fault (G). The backlit LCD provides real-time monitoring of current, voltage, and fault history.

• Drawer-Type Security: The withdrawable chassis includes an automatic safety shutter system that blocks access to the main live busbars when the breaker is removed, ensuring 100% operator safety.

• Zero Arcing Distance: Utilizing advanced arc-extinguishing chambers, the breaker contains the arc plasma internally, allowing for compact switchgear designs and reducing the risk of phase-to-phase flashovers.

• Communication Ready: Supports RS485 Modbus-RTU protocols, enabling seamless integration into Building Management Systems (BMS) and SCADA for remote energy management and status tracking.

1. Industrial Manufacturing: Main incoming breaker for automotive plants, steel mills, and chemical processing facilities.

2. Commercial Real Estate: Centralized protection for high-rise office towers, large-scale malls, and luxury hotels.

3. Data Centers: Reliable 2000A distribution for Tier III and IV server facilities requiring zero downtime.

4. Utilities & Power Plants: Serving as the main LV breaker for step-down transformer substations and auxiliary power boards.

• Total Selective Coordination: Our intelligent trip units provide precise time-current curves, ensuring the 2000A ACB coordinates perfectly with downstream MCCBs to prevent "sympathetic" tripping.

• Maintenance-Friendly Design: The drawer-type unit allows for contact inspection and secondary wiring checks in the "Test" position, keeping the primary circuit safe and isolated.

• Superior Contact Technology: Uses silver-based alloy contacts for low contact resistance and maximum thermal stability during continuous 2000A operation.

• Accessories Included: Units can be equipped with shunt trips, undervoltage releases, auxiliary contacts, and motorized charging mechanisms out of the box.

Q: What is the benefit of the Drawer Type over the Fixed Type?

A: The Drawer Type (withdrawable) is essential for critical applications. It allows you to replace or service the breaker in minutes. It also provides a visible physical disconnection for maintenance safety, whereas a Fixed Type requires busbar disconnection.

Q: Can the 2000A rating be adjusted?

A: Yes. The intelligent trip unit allows you to adjust the rated current (In) setting, typically from 800A up to the full 2000A, to match the specific load requirements of your installation.

Q: Does it support remote operation?

A: If equipped with a motorized operating mechanism and shunt trip, the breaker can be opened and closed remotely from a control room or via a SCADA system.
