GE SR469-P5-HI-A20 Motor Protection Relay

This relay delivers precise control and protection for medium to large industrial motors. Designed for demanding environments, it combines advanced monitoring capabilities with rugged construction to prevent unexpected downtime in critical systems.

Commonly deployed in manufacturing plants, oil refineries, and power generation facilities. Handles harsh conditions like chemical exposure in processing plants or extreme temperatures in steel mills. Works alongside GE’s VMIVME-7807 modules and IS230SRTDH2A communication cards for complete system integration.

A plant engineer from Ohio shared: “After upgrading to this relay, our motor failures dropped by 60% even during summer heatwaves.” Its chemical-resistant coating proved particularly valuable in their facility’s corrosive atmosphere.

Key advantages include:

• Wide voltage compatibility (90-300VDC / 70-265VAC 48-62Hz)
• Redundant power supply options for continuous operation
• Phase imbalance detection with adjustable trip settings
• Thermal modeling to prevent motor overheating
• RS485 Modbus communication for system integration

The large backlit display remains readable in poorly lit maintenance areas. Configuration through EnerVista software allows custom protection curves tailored to specific motor characteristics. Unlike basic relays, this model provides detailed event logs with timestamped fault records.
