Description
GE TGN3325
Technical Specifications
- Manufacturer: General Electric.
- Part Number: TGN3325.
- Type: Electromechanical Contactor / Power Relay.
- Poles: Multi-pole configuration.
Functional Features
- High Inrush Capability: Designed to withstand the high starting currents of industrial motors.
- Mechanical Interlocks: Ensures safe operation and prevents accidental contact closure.
- Long Mechanical Life: Rated for millions of operations.
- Arc Suppression: Built-in arc chutes for safe interruption of high currents.
Application Scenarios
Deployed in motor control centers, HVAC systems, industrial heating, and heavy manufacturing equipment.
Performance Parameters
- Contact Rating: Rated for high AC/DC continuous currents.
- Dielectric Strength: High isolation between coil and power contacts.
- Operate/Release Time: Fast, deterministic switching for precise control.
Material Composition
Silver-cadmium oxide or silver-tin oxide power contacts. Phenolic or thermoplastic housing with copper coil windings and steel magnetic core.
Structural Characteristics
Panel-mount or DIN-rail compatible design. Features heavy-duty power terminals and auxiliary contact blocks. Transparent cover option for visual inspection.
Working Principle
When the control coil is energized, it generates a magnetic field that pulls the armature, mechanically closing the power contacts and allowing current to flow to the load.
Installation Requirements
Mount vertically or horizontally as specified. Ensure adequate clearance for arc quenching and heat dissipation. Torque power terminals to specification.
Usage Precautions
Do not exceed the rated contact load. Use appropriate surge suppression across inductive loads. Inspect contacts periodically for pitting or welding.
