The SR469-P5-HI-A20-E is from GE Multilin and is part of the SR 469 Motor Management Relay line. This unit is designed with 5 amp phase CT secondaries. Designed for use with medium-voltage motors, SR 469 relays offer integrated management and protection. AX Control maintains on-hand stock of a number of different Multilin SR 469 relays.

The SR469-P5-HI-A20-E offers 70-265 VAC, 90-300 VDC control power. This unit has an enhanced front panel. However, if you need a unit that can be used within a harsh environment, please refer to our listing for the SR469-P5-HI-A20-E-H, which is like this unit in every way with the exception of an additional harsh environment conformal coating.

The SR469-P5-HI-A20-E has a well-designed front panel that offers ease of use. The panel includes an RS-232 program port interface with a 9600 baud rate, programmable up to 19,200 baud. This panel has a draw-out handle that can be sealed to prevent any sort of unauthorized removal. The front panel has a large LCD display with forty character capabilities. Users can see diagnostic messages like trips or alarms locally through this display. Additionally, the panel has motor and output status indicators, unit indicators, a numeric keypad, control and programming keys, including a reset, escape, and menu button, and value keys that will allow users to change setpoint values.

What should be done about unbalanced bias of thermal capacity’s and bias K factors with a GE SR469-P5-HI-A20-E Motor Management Relay?

With a GE SR469-P5-HI-A20-E Motor Management Relay having an unbalaned bias of thermal capacity’s, it should be enabled to the thermal capacity usage so the heating effect of the unbalanced bias currents are added to the thermal capacity. With an unbalanced bias K factor the value is calculated by the contribution of the negative current that flows in the rotor due to the unbalance of the K factor. There is a formula that is based on data stats that are empirical to the letter “K”, and it is equal to 230 divided by the per unit locked rotor current that is all squared. The locked rotor amps = 631 percent FLA or 6.31 multiplied by the FLA.

What is the hot and cold curve ratio for this Relay SR469-P5-HI-A20-E?

By using the data sheets from the SR469-P5-HI-A20-E Relay, the safe stall hot and cold time curve ratio is set as 16/18 which is equal to 0.89. The hot and cold curve ratio is simply calculated by dividing the hot safe stall time by the cold safe stall time, the motor thermal limits curve can be used as well.

What is the resistance temperature detector bias maximum rating at for the SR469-P5-HI-A20-E Relay?

The resistance temperature detector bias maximum rating is a settings that is set at the rating for the insulation or set slightly lower. To set the resistance temperature detector maximum bias to a class F insulation is to be rated at 155 degrees celcius in the motor.
