Product Description

The ES5GBF circuit breaker integrates motor protection and thermal relay functions, designed for industrial applications such as manufacturing, energy, and automation. It features 3-phase input and output terminals, directly interfacing with motor control modules, sensors, and PLC systems. Supporting communication via RS-485 or Modbus protocols, it operates within a voltage range of 12–440V AC/DC and withstands ambient temperatures from -20°C to +60°C. The ES5GBF motor protection mechanism combines adjustable overload and short-circuit tripping, while its embedded thermal relay ensures precise temperature monitoring to prevent motor burnout. Notable advantages include compact design, DIN-rail mounting compatibility, and real-time fault diagnostics via LED indicators, though it lacks built-in power monitoring or wireless connectivity. Typical applications involve conveyor systems, pumps, and HVAC equipment. Its overcurrent detection range spans 0.5–100A, enabling flexible configuration for medium-duty motor loads.
