Description
GE CR192C1001000
Technical Specifications
- Type: Definite Purpose Contactor
- Poles: 3 Poles
- Amperage Rating: 100 Amperes
- Voltage Rating: Up to 600V AC
Functional Features
- Provides remote, electrically operated switching of power loads.
- Features silver-alloy contacts for superior conductivity and arc resistance.
- Designed for easy field replacement of contacts and coils.
Application Scenarios
Widely used in HVAC systems, industrial motor starters, lighting control panels, and pump control circuits.
Performance Parameters
- High mechanical and electrical endurance ratings.
- Low power consumption coil design to reduce control circuit heating.
Material Composition
Robust thermoplastic or thermoset base with silver-cadmium oxide or silver-tin oxide contacts and copper current-carrying paths.
Structural Characteristics
Open-frame or enclosed design with clearly marked line and load terminals, and a visible armature mechanism.
Working Principle
When the control coil is energized, it creates a magnetic field that pulls the movable armature, closing the main power contacts and completing the circuit to the load. When de-energized, spring pressure opens the contacts.
Installation Requirements
- Mount securely on a flat, stable surface or DIN rail.
- Ensure control wiring is correctly connected to the coil terminals.
- Verify load voltage and current do not exceed contactor ratings.
Usage Precautions
- Always use properly sized overload relays in series with the contactor for motor protection.
- Inspect contacts periodically for pitting, welding, or excessive wear.
- Ensure the control voltage matches the coil specification to prevent burnout.
