English Description

The Allen-Bradley 269PLUS-100P-120 is a MPR-Plus Motor Protection Relay. This device is a sophisticated electronic relay that offers advanced capabilities beyond traditional thermal overload relays, providing robust protection and detailed diagnostic information for electric motors. It is commonly used in various industrial environments to safeguard motors from conditions like overcurrent, undervoltage, phase imbalance, and high temperature.

Key features and characteristics of the 269PLUS-100P-120 include:

• Product Family: MPR-Plus (Motor Protection Relay Plus).

• Current Range: The "100P" in the part number indicates a 100 Ampere (A) primary current rating. This specifies the maximum current it can directly monitor.

• Control Power Voltage: The "120" in the part number signifies a 120V AC (Alternating Current) control power voltage. This is the voltage required to power the relay itself.

• Protection Functions: The MPR-Plus family provides a wide array of protection features, including:

• Thermal Overload Protection (Class 5-30): Protects the motor from overheating due to sustained overcurrent.

• Phase Loss/Imbalance Protection: Detects missing phases or significant voltage/current imbalances that can damage the motor.

• Stall Protection: Protects against motor damage during locked rotor conditions.

• Undercurrent/Overcurrent Protection: Monitors for loads that are too low or too high.

• Jam Protection: Detects conditions where the motor is overloaded to the point of stalling or near-stalling.

• Ground Fault Protection: Protects against electrical shock and equipment damage caused by current leakage to ground.

• Under/Over Voltage Protection: Safeguards the motor from voltage fluctuations.

• Power Factor Monitoring: Can monitor the power factor of the motor.

• Communication: Typically supports communication protocols such as Modbus RTU or DeviceNet, allowing for integration into larger control systems (PLCs, DCS) for remote monitoring, control, and data acquisition.

• Display and Keypad: Features a built-in liquid crystal display (LCD) and keypad for local programming, status viewing, and diagnostic data retrieval.

• Diagnostic Information: Provides extensive diagnostic data, including trip history, motor operating parameters (current, voltage, power factor), and event logs, aiding in troubleshooting and predictive maintenance.

• Mounting: Designed for direct mounting to contactors or stand-alone mounting on DIN rails or panels.

• Applications: Widely used in pump control, fan control, conveyor systems, compressor control, and other applications where reliable motor protection and detailed operational insights are crucial.
