ABB 87TS50E-EKey features
Thermal overload protection: ABB 87TS50E-E Based on the I²t algorithm to simulate the motor thermal model, accurately match the motor thermal characteristics.
Electrical fault protection: phase loss, reverse phase, current imbalance (adjustable threshold, starting from ±10%).
Mechanical fault detection: stall protection (instantaneous action), start timeout protection.
Intelligent control Direct start/star-delta start: ABB 87TS50E-E built-in logic control, reducing the need for external contactors.
Modbus RTU communication: supports RS485 interface and is integrated into SCADA/DCS system.
User-friendly design
LCD display: real-time display of current, voltage, fault code (such as F01 overload).
Menu navigation: configure parameters through panel buttons without dedicated software.
