The 193-EC2CB is an E3 Plus Electronic Overload Relay for industrial motor control systems. It features an adjustable full-load current range of 5 to 25 A and an adjustable trip class from 5 to 30. Utilizing solid-state sensing technology, the device monitors motor operating conditions to provide protection against overload, phase loss, and current imbalance.
5...25 A Current Range: Integrated primary loop monitoring
Internal Ground Fault Protection: No external CT required
The 193-EC2CB provides electronic overload protection with integrated diagnostics and programmable operating parameters for motor control and maintenance systems. The relay utilizes True RMS current sensing to monitor single-phase and three-phase motors operating at 50/60 Hz. Adjustable trip configurations, programmable warning parameters, and a manual Test/Reset interface adapt the protection characteristics to specific motor requirements. The hardware delivers diagnostic data and status indications to isolate overload conditions during troubleshooting phases.

Oil & Gas Extraction
Used for current monitoring and overload protection of motors driving water injection pumps and associated gas compressors in oil production fields.
Petrochemical & Refining
Applied to provide phase loss and current imbalance protection for low-voltage explosion-proof centrifugal pumps and material agitator motors in chemical plants.
Thermal Power Plants
Serves as the protection core in Motor Control Center (MCC) cubicles for coal handling systems, pulverizing systems, and low-voltage auxiliary drives in power plants.
Iron & Steel Metallurgy
Applied for overload trip protection of charging hoists, slag pot carriers, and small-to-medium converter auxiliary tilting drive motors in steel mills.
Paper & Printing Industry
Provides long-term continuous thermal overload protection for pulp transfer pumps and small chest agitators in the papermaking section.
Pharmaceuticals & Bio-chemicals
Protects critical low-voltage power distribution loops for cleanroom HVAC circulation fans and autoclave circulation pumps.
When wiring, pass the main motor cables through the internal CT windows. Ensure the Full Load Amps (FLA) and trip class are configured accurately based on the motor nameplate.
Maintain correct DeviceNet network termination resistors to prevent communication failures during operation. As this series is discontinued, it is recommended to pre-plan and stock lifecycle replacement solutions (such as the E300 series).
