GE 469-P1-HI-A20 Motor Management Relay

The GE Multilin 469-P1-HI-A20, also cataloged as the 469-P1-HI-A20 Motor Management Relay, operates as a dedicated hardware component for executing motor protection, phase current monitoring, and trip logic across industrial drive platforms.

Suffix Breakdown & Model Matrix

The model 469-P1-HI-A20 belongs to the GE Multilin 469 Motor Management Relay series. Based on standard part number configuration rules, the base designation identifies the 469 relay platform, while the specific suffix string encodes the individual hardware options: P1 denotes 1 A phase CT secondaries, HI specifies DC 90 to 300 V or AC 70 to 265 V control power at 48 to 62 Hz, and A20 indicates 4-20 mA analog outputs.

Hardware Specifications

Backplane Bus Communication Velocity & Network Interfaces

The module manages motor protection algorithms via deterministic internal processing loops. Configurable firmware flash compatibility and backplane bus communication velocity ensure data synchronization across connected control networks. Integrated analog outputs deliver 4-20 mA scaling for continuous variable tracking, while digital current monitoring paths handle phase inputs derived from 1 A secondary current transformers.

Frequently Asked Questions

Q: Does the motor management relay support hot-swap replacement under live system power?

A: No, control power and primary current feeds must be completely de-energized prior to extracting or inserting the GE Multilin 469-P1-HI-A20 module to prevent internal component damage and unexpected tripping.

Q: How are current transformer inputs configured for this specific model?

A: The P1 designation indicates that the hardware is built specifically to accept 1 A phase CT secondaries directly into its sensing terminals.

Field Installation Guidelines

Mount the relay securely into a standard industrial panel enclosure, maintaining proper IP40 protection standards on the front face and IP20 at the rear. Route current transformer leads and control power cables separately from high-voltage switching circuits to minimize electromagnetic interference. Verify that operating temperatures remain within the -40 deg C to +60 deg C range and check all terminal torque specifications prior to system energization.
