GE 489-P5-HI-A20-E SR489 Detailed Information

The GE 489-P5-HI-A20-E SR489 is a generator management relay manufactured by GE Multilin for the 489 series. It’s designed to protect and manage synchronous and induction generators used in power generation applications.

Here’s a breakdown of the code in the model number:

• 489: Indicates the relay series.
• P5: Specifies 5 Amp phase current secondaries. This means the relay is designed to work with current transformers (CTs) that output a secondary current of 5 Amps.
• HI: Denotes high control power rating (90-300 VDC and 70-265 VAC at 48-62 Hz).
• A20: Signifies 4 to 20 mA analog outputs for interfacing with other control systems.
• E: Represents a basic display.

Key features of the GE 489-P5-HI-A20-E SR489:

• Microprocessor-based protection and control.
• Multiple protection functions like overcurrent, undercurrent, loss of excitation, and ground fault detection.
• Monitoring capabilities for various generator parameters like voltage, current, power, and frequency.
• Basic display for viewing relay status and measurements.
• 4-20 mA analog outputs for integration with control systems.

GE Company

GE Fanuc was a joint venture between General Electric (GE) and FANUC that existed from 1986 to 2009. The company specialized in industrial automation products, including programmable logic controllers (PLCs), human-machine interfaces (HMIs), and SCADA systems.

• Programmable logic controllers (PLCs)
• Industrial robots
• CNC controls
• Motion control systems
• Human-machine interfaces (HMIs)
• Industrial software

Delivery Time :

• Express Shipping (DHL, UPS, FedEx, EMS):3-10 working days is a good rule of thumb. These services prioritize speed and often offer features like next-day or guaranteed delivery by a certain date (for an additional fee).
• Air Mail (China Post, Hong Kong Post):7-35 working days, depending on the destination country. This is a more budget-friendly option, but it takes longer because it has lower priority for shipment.

Affect delivery times:

• Customs Clearance:If customs officials need to inspect your package more thoroughly, it can delay delivery.
• Distance:Packages traveling longer distances will naturally take longer.

Important Notes:

• Please follow the product’s instruction manual carefully for installation and debugging to avoid damage to the product.
