| Minimum Order Quantity: | 1piece | Supply Ability: | Available at any time |
An air circuit breaker (ACB) operates by automatically cutting off current when it detects an overload or short circuit. During normal operation, its main contacts remain closed, allowing current to flow freely.
When a sustained overcurrent occurs, the thermal element bends due to heat, triggering the circuit breaker mechanism. In the event of a sudden short circuit, the solenoid coil generates a momentary magnetic force that trips the circuit breaker mechanism. This action rapidly separates the main contacts.
A strong electric arc is generated between the separated contacts and is immediately sent to the arc-extinguishing chamber, where the arc is broken up, cooled, and extinguished, thus safely disconnecting the circuit and preventing system damage.
Units are disassembled to remove the copper busbars and side plates for replating or complete replacement. Replated busbars offer high conductivity and resistance to oxidation and corrosion.
Models 2.0, 2.0A, 2.0E, 5.0A, and 5.0E are tested and verified. Basic protection, alarm signaling, earth leakage, and energy monitoring with communication options are fully available.
Proper motor operation is verified so units open and close correctly. Small motors (NT/N1 series) are used for under 2000A, while large motors (NW/H1 series) serve currents above 2000A.
Tips: Internal accessories are also available for separate purchase.
The Air Circuit Breaker (ACB) is designed for the primary protection and control of electrical power distribution networks. It serves as a critical safety component in low-voltage systems, reliably interrupting fault currents and preventing damage to downstream equipment from overloads and short circuits. Its robust design ensures operational continuity and safety for personnel and assets in industrial plants, commercial buildings, and large infrastructure projects.
Outer packaging: Strong wooden boxes are usually used to provide sufficient mechanical strength. Wooden crate suitable for large circuit breakers or international transportation.
Inner packaging: Wrap the circuit breaker with buffer materials such as foam pad, bubble film or pearl cotton to prevent vibration and collision. For large circuit breakers, the packaging box may adopt a layered design, with accessories (such as manuals, tools, spare parts) placed on the upper layer.
Domestic transportation: For designated freight forwarders in China, products are transported to the designated location through road transportation or domestic express delivery after production is completed.
International transport: When the quantity of goods is small and time is tight, the three major international express delivery companies (DHL, FEDEX, UPS) are selected for rapid transportation to overseas destinations.
Sea freight/air freight: For large shipments, sea freight is selected. Suitable freight companies arrange for truck pickup and transportation to the designated port for warehousing and final sea shipment to the destination port.
