Description
GE FULOS000 Turbine Control Switch Assembly
Product Dimensions：
The GE FULOS000 (GE General Electric / ABB Industrial Solutions) is a side-mounted auxiliary contact block designed for the FUL00 series of load break switches and switch disconnectors. It provides auxiliary control, indication, and interlocking feedback by converting the main mechanical switch position into standard electrical signals for control circuits, PLCs, and alarm panels.

Key Advantages
- High Reliability: Engineered with self-cleaning contacts that maintain low contact resistance even in low-voltage PLC signal circuits.
- Modular Integration: Snaps directly onto the side of FUL00 series switch disconnectors without requiring special tools or hardware modifications.
- Compact Footprint: Adds minimal width to the main switch unit, saving valuable panel space.
- Dual Feedback Signals: Provides both NO and NC states simultaneously to allow simultaneous switching status indication and interlocking loops.
- Safety & Compliance: Meets international standard IEC/EN 60947-5-1 for low-voltage control circuit devices.
Recommended Applications
- Remote Status Monitoring: Transmitting the main switch’s ON/OFF state to a PLC, SCADA system, or remote indicator light panel.
- Control Circuit Interlocking: Preventing secondary equipment (such as contactors or drives) from energizing until the main load disconnector is closed.
- Safety Alarm Loops: Triggering audible or visual warnings when the main disconnector is operated or manually tripped.
- Industrial Control Panels: Used in low-voltage distribution boards, motor control centers (MCC), and switchgear.
Precautions & Installation Notes
- Safety First: Ensure the main power supply to the switch disconnector and auxiliary circuit is completely de-energized prior to installation, wiring, or maintenance.
- Proper Alignment: Verify that the mechanical actuator arm of the FULOS000 correctly aligns with the internal drive mechanism of the FUL00 base switch before snapping it into place.
- Torque Tightening: Use the manufacturer-recommended torque when securing terminal screws to avoid stripped threads or loose, high-resistance connections.
- Current & Voltage Limits: Do not exceed the 10 A thermal current rating or the maximum voltage rating (U_e = 690 V) to prevent premature contact welding or insulation degradation.
