Air Circuit Breaker Frame Accessory

High-Performance Frame Accessories for Industrial Air Circuit Breakers

With 42 years of experience in manufacturing high and low voltage electrical components, our factory specializes in the independent R&D and production of Air circuit breaker frame accessory (1000A/1600A air circuit breaker frame accessory assembly). As a core protection component for MNS low voltage switchgear and power distribution cabinets, this product covers two mainstream current ratings of 1000A and 1600A.

The Air circuit breaker frame accessory adopts a modular frame structure and integrates multiple protection functions, including long-time overload protection, short-time short-circuit protection, and instantaneous protection. Equipped with intelligent trip units, it supports remote communication, fault recording, and real-time monitoring of current and voltage parameters. With a maximum breaking capacity of 85kA, it is widely used in high-power industrial systems, low-voltage sides of energy storage projects, and commercial power distribution applications.

Our 36,000㎡ production facility is equipped with automatic coil winding machines, PCBA online inspection equipment, and precision assembly testing systems. Each Air circuit breaker frame accessory undergoes strict quality control procedures, including incoming material RoHs inspection, iron core bonding adjustment, power frequency withstand testing, electrical characteristic inspection, and high-temperature aging testing.

Any component failing inspection is immediately transferred for rework or rejection. All finished products undergo 100% inspection before shipment with complete inspection records retained. Our company complies with ISO14001 environmental management requirements, and all raw materials meet RoHs2.0 and REACH environmental standards.

We have long-term cooperation experience supplying air circuit breaker frame components for leading electrical brands such as Chint and Delixi. Products are exported in batches to electrical distributors in Southeast Asia and the Middle East. Overseas customers have verified that this Air circuit breaker frame accessory achieves more than 10,000 mechanical operation cycles, with protection action accuracy within ±3%. Compared with common market alternatives, the failure rate is reduced by 58%, significantly lowering maintenance and replacement costs for overseas switchgear manufacturers.

Our professional R&D team continuously optimizes protection structures for different global 50/60Hz power systems. The products can be adapted to various domestic and international low-voltage switchgear systems, providing electrical distributors with reliable, high-compatibility circuit breaker core components.

OEM/ODM Customization for Global Electrical Manufacturers

For global low-voltage switchgear manufacturers and electrical component distributors, our 1000A and 1600A Air circuit breaker frame accessory products support comprehensive OEM/ODM customization.

Customers only need to provide switchgear drawings, circuit breaker installation dimensions, and protection requirements. Our engineering team can develop matching frame accessories according to actual application needs.

The minimum order quantity is only 1 piece. Customized samples can be developed within 1–3 months, and testing samples can be provided for complete machine assembly verification under agreed conditions.

Before production, our electrical engineers provide remote product selection support and recommend suitable frame accessories according to rated current and breaking capacity requirements.

During manufacturing, customers can request real-time photos and videos of component processing and aging tests. Long-term partners receive priority production scheduling for repeat orders to shorten delivery times.

Each Air circuit breaker frame accessory includes an 18-month factory warranty from the shipment date. Our dedicated after-sales team provides technical support for overseas customers. If frame deformation or trip unit damage occurs during transportation, replacement or return solutions can be arranged.

Third-party factory inspections are also supported according to customer-confirmed technical standards.

Our electrical component production capacity reaches 50,000 sets per month. Standard 1000A and 1600A Air circuit breaker frame accessory models are available from stock. Standard products can be shipped within 5 working days, while customized accessories with intelligent communication modules or non-standard installation dimensions can be delivered within 7–15 days.

Different current specifications can be mixed in one order for combined shipment. Large annual purchasing projects can receive flexible tiered pricing. Through direct factory supply, we help overseas switchgear manufacturers reduce procurement costs while providing complete customization, production, export protection, and after-sales support.
