Description
GE 12SGC21A1A
Technical Specifications
- Manufacturer: General Electric (GE)
- Product Type: Control Relay / Contactor
- Series: GE SGC Series
Functional Features
- Load Switching: Controls AC/DC loads with high reliability.
- Auxiliary Contacts: Provides feedback contacts for control circuit interlocking.
- Mechanical Durability: Rated for millions of mechanical operations.
Application Scenarios
- Motor Starting: Direct-on-line and reduced-voltage motor starting.
- Control Logic: Interlocking, sequencing, and pilot duty applications.
Performance Parameters
- Contact Rating: Rated for specified AC/DC voltage and current.
- Coil Voltage: Operates at standard control voltages.
Material Composition
Silver-alloy contacts for arc resistance; thermoplastic housing for electrical insulation.
Structural Characteristics
- Form Factor: Standard relay/contactor footprint.
- Mounting: Socket mount or direct panel mount.
Working Principle
Energizing the coil creates a magnetic field that closes the main contacts, allowing current to flow to the load. Auxiliary contacts change state simultaneously for control feedback.
Installation Requirements
- Install in a compatible socket or secure directly to the panel.
- Ensure adequate clearance for heat dissipation and arc flash safety.
Usage Precautions
- Never exceed contact voltage or current ratings.
- Use proper wire crimps and torque specifications for all connections.
