Drawer Fixed Type Intelligent Air-Circuit Breaker

It is designed to distribute electrical energy and protect power circuits and equipment from overload, undervoltage, short circuit, and single-phase ground faults. Its intelligent control unit provides real-time monitoring, precise parameter settings, and fault diagnostics.

Drawer Type (as shown in the images): The breaker is mounted on a chassis with sliding rails. It allows for quick plug-in and withdrawal for easy maintenance or replacement without disconnecting the main busbar power. Fixed Type: The breaker is directly bolted onto the mounting plate. It is more cost-effective but requires full power shutdown for maintenance.

This YFW1 series typically covers a wide range, such as 630A, 800A, 1000A, 1250A, 1600A, 2000A, 2500A, 3200A, and 4000A. The exact model depends on your power distribution requirements. (Check the nameplate for the specific rating you require).

Yes. The intelligent control unit is equipped with standard communication interfaces (e.g., RS485 with Modbus protocol). It can be integrated into an automated control system for remote monitoring, data logging, and centralized management.

Red Button (Push to Trip): Used for manual emergency tripping or testing the mechanical trip function. Green Button (Close/On): Used for manual closing (switching on) the circuit breaker. There is also a charging handle for manual energy storage.
