Description

GE SR469-P5-HI-A20-E-H Motor Management Relay – Multilin SR469 Series

When a critical motor fails unexpectedly on the plant floor — a compressor drive, a pump motor, or a conveyor system — the consequences cascade instantly: unplanned downtime, production loss, and potential equipment damage that can cost tens of thousands of dollars per hour. Without intelligent motor protection, operators are left reacting to failures rather than preventing them. The GE Multilin SR469-P5-HI-A20-E-H Motor Management Relay changes that equation entirely, providing comprehensive real-time protection and monitoring that keeps motors running safely and reliably.

The SR469-P5-HI-A20-E-H is a fully featured variant within GE’s industry-leading Multilin SR469 Motor Management Relay series — one of the most widely deployed motor protection platforms in global industrial automation. Engineered for medium-voltage motor applications, this specific configuration (P5 power supply, HI current input, A20 CT ratio, E enhanced I/O, H HART communication) represents the premium tier of the SR469 family, trusted by engineers across power generation, oil & gas, mining, and heavy manufacturing worldwide.

Frequently Asked Questions

Q: What does the “P5” suffix mean in SR469-P5-HI-A20-E-H?
A: P5 designates the universal power supply module, accepting 85–265 V AC/DC input, making the relay suitable for installation in both AC and DC substation environments without requiring a separate power supply.

Q: What is the difference between SR469 HI and LO current input options?
A: The HI (high current) input module is designed for applications where the CT secondary current is higher than standard 5 A, accommodating large motor feeders. The LO option is for standard 5 A CT secondary applications.

Q: Does the SR469-P5-HI-A20-E-H support Modbus communication?
A: The standard SR469 supports RS-485 Modbus RTU. The H option in this model adds HART protocol capability. For Ethernet/IEC 61850 communication, the SR469 Plus variant should be considered.

Q: Can this relay replace an older GE Multilin 469?
A: Yes, the SR469 series is the direct successor to the 469 Motor Management Relay and is designed as a drop-in upgrade with enhanced functionality. Panel cutout dimensions and wiring are largely compatible.

Q: What is the warranty on units supplied by Konmask.com?
A: All units are supplied with our standard quality guarantee. Please contact support@konmask.com for specific warranty terms applicable to your order.

Q: Do you provide the EnerVista configuration software with the relay?
A: GE EnerVista software is freely available from GE Grid Solutions. We can assist with sourcing the correct version compatible with your SR469 firmware upon request.
