Core Product Advantages
1. High Compatibility, Direct Replacement
- The dimensions and mounting hole positions are fully compatible with the original LS ABE403B, allowing direct replacement without cabinet modification, reducing operation and maintenance costs.
- The electrical parameters are 1:1 aligned, with consistent protection characteristics, which will not affect the protection logic of the original power distribution system.
2. High Reliability and Safety Guarantee
- Adopts a high-quality molded insulating shell, resistant to impact and aging, adapting to complex industrial environments such as high and low temperatures and humidity.
- The thermal-magnetic tripping mechanism is accurate and reliable, with sensitive overload protection action and fast short-circuit breaking, effectively protecting back-end equipment and lines.
- Long mechanical life, up to tens of thousands of operations, short maintenance-free cycle, reducing operation and maintenance workload.
3. High Cost-Effectiveness, Quality Benchmarking
- Produced to the quality standards of international brand products of the same specification, with more favorable prices, making it the preferred solution for import substitution.
- Full-process quality control, 100% inspection before delivery, ensuring stable performance and high consistency of each product.
4. Flexible Adaptation, Wide Application
- Suitable for all types of low-voltage power distribution scenarios such as factory power distribution, commercial buildings, data centers, and photovoltaic energy storage.
- Can be equipped with accessories such as auxiliary contacts and shunt trip devices to meet extended requirements such as remote control and signal feedback.
4. Product Appearance and Structure
The product adopts a modular and compact design with a gray and white color scheme. The front is equipped with an operating handle, a status indicator window and a red fault indicator. The wiring terminals are clearly arranged, supporting busbar/cable wiring, easy to install and maintain.
5. Applicable Scenarios
- Main power distribution and branch power distribution protection in industrial plants
- Power distribution systems of commercial complexes and high-rise buildings
- Overload and short-circuit protection for power equipment such as motors and inverters
- Power distribution protection in photovoltaic grid-connected and energy storage systems
- Power distribution protection of key loads in data centers and computer rooms
6. Selection and Replacement Instructions
This product can directly replace the original LS Electric ABE403B 3P 400A circuit breaker, and is also compatible with the replacement needs of molded case circuit breakers of other brands of the same specification. When selecting, only need to confirm:
- Frame current 400AF, rated current 400A, 3-pole
- Breaking capacity meets the on-site short-circuit current requirements
- Installation dimensions match the cabinet opening holes
