Real-World Applications

Primarily deployed in heavy industrial settings, this relay excels in motor protection applications across oil & gas facilities, manufacturing plants, and power generation stations. Its digital input capabilities and tachometer monitoring make it particularly valuable for:

• Continuous process lines requiring 24/7 operation
• High-vibration environments where mechanical relays degrade rapidly
• Systems needing precise underfrequency detection (±0.02Hz accuracy)

For instance, a mid-sized refinery in Texas reported 40% reduction in motor-related downtime after upgrading to SR489 relays. We commonly supply this model alongside other GE protection relays like the SR469-P5-HI-A20 and IS230SRTDH2A for integrated motor management systems.
