GE SR469-P5-HI-A20

Description

GE SR469-P5-HI-A20 is a motor management relay from GE Multilin.The following is a detailed introduction to the product:

I.Main features

Applicability:SR469-P5-HI-A20 is a protection relay designed for medium-voltage motors.It has multiple protection functions and can effectively ensure the safe operation of the motor.

Analog output:It provides four 4-20mA analog outputs,which can be used to monitor various status parameters of the motor.

Control power supply:It supports a wide range of control power input,including 90-300VDC and 70-265VAC(48-62Hz),which increases the flexibility of use.

Resistor temperature detector bias:It has a resistor temperature detector bias function,which can be used for hot and cold safety protection of the motor.By enabling the resistor temperature detector bias,the temperature of the stator sensor will be enabled and included in the calculation of the thermal capacity.

Drawout structure:It adopts a drawout structure,designed for quick replacement,which is convenient for users to maintain and replace.

Communication function:It supports Modbus RTU communication protocol,which is convenient for communication and data exchange with the host computer or other control systems.

2.Technical Parameters

Device Type:Standard device with 5A phase CT secondary coil.

Grounded CT Input:One of the two grounded CT inputs is designed for GE power management,and the other is for grounded CT.

VT Input:Adapts to VT in delta or star configuration.

Motor Thermal Model:Provides functions such as RTD bias,motor cooling time constant,start inhibition and emergency restart,unbalanced bias and overload curve.

Hot and cold safety stall ratio:With this function,it can be used for motor safety protection.
