Description
GE 269PLUS-10C-120
Technical Specifications
- Product Type: Solid-State Motor Management Relay.
- Control Voltage: 120V AC.
- Series: 269 Plus.
- Frame Size: 10C.
Functional Features
- Comprehensive Protection: Protects against overloads, phase loss, phase unbalance, ground fault, and underload.
- Real-Time Monitoring: Continuously displays motor current, voltage, power factor, and thermal capacity used.
- Communications: Supports Modbus RTU for integration into plant-wide SCADA systems.
Application Scenarios
Deployed in motor control centers (MCCs) and industrial facilities to protect critical pumps, fans, compressors, and conveyors.
Performance Parameters
- Current Range: Adjustable over a wide range to match motor full load amps (FLA).
- Trip Class: Selectable trip curves for precise thermal overload matching.
Material Composition
Housed in a rugged, flame-retardant plastic enclosure with a digital display and push-button interface. Internal circuitry utilizes solid-state current transformers and microprocessors.
Structural Characteristics
Compact DIN-rail or panel-mount form factor. Features a front-panel LCD display for local diagnostics and configuration.
Working Principle
Continuously samples motor current and voltage via internal sensors, calculates thermal models and electrical parameters, and opens the control circuit if unsafe operating conditions are detected.
Installation Requirements
Must be wired according to the manufacturer’s wiring diagram. Ensure the control voltage (120VAC) matches the relay specification. Route motor leads away from sensitive communication wiring.
Usage Precautions
Always verify motor FLA and service factor before configuring the relay. Perform a functional test of the trip circuit before placing the motor in service.
