ABB REC650 is a multi-function circuit breaker for a wide range of applications in power systems and industrial automation. Here are some of the key features and functions of REC650:

Multi-function protection: REC650 circuit breakers support over current, overload, short circuit, ground fault and other protection functions to ensure the safe operation of the power system.

Intelligent control: With intelligent control function, it can adjust the protection parameters and action logic in real time according to the running status of the power grid to improve the reliability of the system.

High precision measurement: built-in high-precision measurement function, can real-time monitoring of power system voltage, current, frequency and other parameters.

Communication interface: Supports a variety of communication interfaces, such as IEC 61850, Modbus, etc., to facilitate data exchange and system integration with other devices.

Environmental adaptability: It can work stably in a sealed, impervious environment and is suitable for a variety of harsh environmental conditions.

Programming and interface: Programming with Divis Ladder software, which supports ladder diagram and function block programming. Input power ranges from 8 to 32VDC, and the input/output feature includes six 8-32VDC inputs, two of which can be independently selected as field leaks or procured. With 40 KHZ high-speed counting capability, there are two 10-bit analog channels with optional fields ranging from 0-5VDC, 0-10VDC or 0-20MA. There are six digital/pressure tube outputs, each rated at four amps, with automatic overcurrent safety and programmable condition monitoring.
