ABB 1TGE120021R0010 Microcomputer motor protection relay

ABB 1TGE120021R0010

This is a powerful and cost-effective motor management solution. It’s not just a simple upgrade to a thermal relay, but a smart device integrating protection, measurement, control, and communication. It helps users improve the reliability and safety of their production processes, optimize energy use, and achieve predictive maintenance.

Core Product Overview

• Brand: ABB

• Product Line: ESI® Edge (Energy Saving Initiative – Edge)

• Product Type: Microprocessor-Based Motor Protection Relay / Motor Management Relay

• Core Function: Provides comprehensive protection, monitoring, control, and management for low-voltage three-phase AC motors.

Key Features & Characteristics

1. Motor Protection

This is its core function, designed to prevent motor damage from various electrical faults, thereby extending motor life and reducing unplanned downtime.

• Overload Protection: Simulates the thermal characteristics of a motor to prevent burnout from prolonged overcurrent.

• Phase Loss/Unbalance Protection: Detects the loss of a phase or severe current unbalance, which can cause motor overheating.

• Stall Protection: Quickly trips the relay if the motor is blocked during start-up or operation, causing a rapid current increase.

• Earth Fault/Leakage Protection: Detects insulation faults to earth in the motor or cable, preventing electric shock and equipment damage.

• Short-Circuit Protection: Provides rapid protection against short-circuit currents.

• Underload/No-Load Protection: Detects abnormal conditions such as pump dry-running or conveyor belt load loss.

• Start Time Supervision: Monitors the motor’s starting sequence and trips if the start time is excessively long.

2. Measurement & Monitoring

It continuously monitors various parameters in the motor circuit and displays them via its screen or communication interface.

• Current: Three-phase currents, earth fault current

• Voltage: Line voltage (requires optional voltage module)

• Power: Active power, reactive power, power factor

• Energy: Consumed active and reactive energy

• Thermal Capacity: Displays the real-time percentage of the motor model’s remaining thermal capacity.

3. Control Functions

• Direct-On-Line (DOL) Starting Control: The most common method for starting motors.

• Programmable Inputs/Outputs: Provides multiple digital inputs and relay outputs for connecting start/stop buttons, fault reset, remote signaling, or controlling contactors, valves, etc.

• Under-voltage Ride-Through: Keeps the motor from tripping during brief voltage dips, allowing it to continue running once voltage recovers.

4. Communication & Integration

• Communication Interface: Typically equipped with the Modbus RTU protocol via an RS485 interface, allowing for easy integration into PLC, DCS, or SCADA systems.

• System Integration: Enables remote monitoring of motor status, reading of measured values, receiving alarms and fault information, and performing remote start/stop control.

5. Diagnostics & Maintenance

• Event Logging: Records the most recent trip events and their causes, aiding in rapid troubleshooting.

• Running Hour Counter: Records total motor operating hours, providing data for predictive maintenance.

Typical Applications

This relay is widely used in industrial sectors requiring reliable motor control, such as:

• Water & Wastewater Treatment (Pump control)

• Oil & Gas Industry

• Chemical & Process Industries

• Mining

• Building Materials Industry (Fans, crushers, conveyors)

• HVAC Systems

Physical & Installation Characteristics

• Mounting: Typically designed for DIN-rail mounting, facilitating easy installation in distribution cabinets.

• Display: Features a backlit LCD screen for displaying measured values, status, and the configuration menu.

• Form Factor: Compact design to save space in control panels.
