الوصف
The GE DS2020LPPA301A Line Protection Module is a crucial printed circuit board (PCB) component used in General Electric’s industrial control systems, specifically within the Mark V turbine control and drive series.1
Its primary function is to act as a Current Limiter/Protector, safeguarding downstream equipment and the entire system from damaging electrical faults.2
🛡️ Key Specifications and Function
| Feature | Specification/Description |
| Product Type | Line Protection Board / Current Limiter/Protector |
| Series/Family | GE Mark V Turbine Control Systems and Industrial Drives |
| Primary Function | Line Protection. Monitors incoming power lines (AC input) for electrical disturbances such as overcurrents, short circuits, and other faults, and is designed to mitigate or isolate the fault condition. |
| Current Rating | It is commonly specified as a 30 Amp Line Protector. The “30” in the part number often relates to this current rating. |
| System Voltage | Rated for high-voltage industrial applications, typically up to 600 VAC. |
| PCB Features | Like its counterparts, it is equipped with jumpers (JP1-JP7) and terminal blocks for system configuration, signal connections, and diagnostics. |
| Status | This module is frequently listed as discontinued by the manufacturer (GE), though it remains available through surplus and repair markets. |
Part Number Breakdown
The component designations are standard for this GE module family:
- DS2020: Indicates the product generation/family (associated with the Mark V drive’s modular architecture).
- LPPA: Stands for Line Protection Panel Assembly.3
- 301A: Specifies the 30 Amp rating and the revision level (the ‘1’ often indicates a minor revision or a variant from the DS2020LPPA300A).
In a control cabinet, the DS2020LPPA301A acts as a vital safety barrier, contributing significantly to the reliability and operational longevity of the drive or turbine control system by minimizing the risk of catastrophic failure from electrical surges.4
