🛡️ The GE DS2020LPPB320A Line Protection Panel Board is a specialized, high-voltage printed circuit board (PCB) module designed by General Electric for their robust industrial control platforms.
It is part of the Line Protection Panel B (LPPB) family, meaning it is built to handle higher system voltages and currents than the ‘LPPA’ variants.
⚡ Key Technical Specifications
| Feature | Specification/Description |
| Product Type | Line Protection Board / Module (LPPB) |
| Series/Family | GE Mark V Turbine Control Systems and EX2000 Excitation Systems |
| Primary Function | High-Voltage Fault Protection. It serves as a safety barrier, protecting sensitive control circuitry from damaging electrical disturbances on the incoming power lines, such as overcurrents and voltage transients. |
| Current Rating | Based on the product family’s typical structure, the 320A suffix most often indicates a 32 Amp continuous current rating. |
| Voltage Class | High Voltage. The ‘LPPB’ designation confirms it is rated for higher voltage systems, generally in the 601 VAC to 1500 VAC range, or high-voltage DC applications (e.g., up to 1000 VDC), distinguishing it from the LPPA variants (typically 230–600 VAC). |
| Components | Contains internal components for surge suppression (like MOVs) and current sensing to ensure rapid fault isolation. |
| Application | Critical for maintaining the safety and reliability of high-power DC drives and excitation control systems for large generators and motors. |
Part Number Breakdown
- DS2020: Designates the product family (associated with the modular Mark V and EX2000 architectures).1
- LPPB: Stands for Line Protection Panel Board (The ‘B’ indicates suitability for a higher voltage class).
- 320A: Specifies the current rating (likely 32 Amps) and the revision level.
The DS2020LPPB320A is a vital component in industrial power electronics, acting to minimize equipment damage and downtime by isolating severe electrical faults quickly and reliably.2
