EMT6 Electric Motor Protection Relay

Art. EMT6

Protecting electric motors is one of the most important tasks in the electrical equipment of industrial machines. Eaton offers a wide range of products (from simple bimetallic relays to full-featured motor protection devices), allowing you to find the most suitable option for any application.

This equipment is used to protect machines from overheating during frequent or difficult starts, braking, or undervoltage or overvoltage. The EMT6 protection relay receives a signal from a temperature sensor and, when a certain level is exceeded, triggers a shutdown signal. These devices can be used to monitor the temperature of oil, coolant, gearboxes, and bearings. Eaton offers the following types of thermistor protection relays.

EMT 6. These devices are equipped with galvanic isolation between the sensor and power supply circuits for increased safety.
EMT 6-DB. This device is equipped with a manual and automatic control switch, a test button, and LED indicators for network connection and operation.
EMT 6-DBK. These devices feature built-in manual and automatic reset functions, short-circuit detection, and power failure alarms. This equipment can be used in any circuit equipped with thermistor sensors.
EMT 6-K. These devices have a built-in short-circuit detection function in the sensor circuit. The relay is activated when the resistance drops below 20 ohms.
EMT 6-KDB. This equipment is equipped with a reset switch for automatic or manual mode and a test button. The EMT 6-KDB also protects machines from voltage drops and short circuits in the sensor circuit.

Overload relay

An overload relay is a modern device that provides reliable protection for electric motors against overloads and short circuits. This equipment is an integral part of the motor automation and control system, offering a variety of advanced features and benefits.

Power Technology Solutions is an official distributor of American and European relay manufacturers, enabling us to deliver high-quality products to customers quickly while providing a high level of technical and informational support.

Intelligent engine control

The devices are available in a variety of configurations, including EtherNet/IP, DeviceNet, and standalone solutions. This allows the overload relay to be integrated into any existing control system, providing high flexibility and adaptability.

Modular solution

The overload relay's design allows for easy adaptation to specific system requirements. A wide current range and adjustable tripping class ensure precise adjustment and protection for various motor types. Modularity also simplifies installation and maintenance, as individual modules can be replaced or upgraded without replacing the entire device.

Extended diagnostic information

The voltage monitoring relay provides extensive diagnostic information, which is especially important for single- and three-phase applications. This includes data on the current motor status, overload history, and potential fault information. This allows operators to quickly identify and resolve issues, minimizing downtime and improving overall system efficiency.

Built-in I/O

Motor overload relays include built-in inputs/outputs, allowing for expanded functionality. Additional modules are used to connect additional sensors and devices, providing more comprehensive system monitoring and control.

Simplified connectivity and integration into Logix

Overload protection devices offer simplified wiring and easy integration with Logix technology. This reduces the time and cost of system installation and configuration. Integration with Logix provides centralized control and monitoring of all connected devices, increasing the overall reliability and efficiency of the control system.
