Description
GE CR2962E2C
Technical Specifications
- Product Type: Magnetic Contactor.
- Series: CR296 Series.
- Voltage Rating: 600 Volts AC Maximum.
- Pole Configuration: Multi-pole design for three-phase power systems.
Functional Features
- Motor Starting: Designed for full-voltage starting and stopping of AC induction motors.
- High Current Switching: Capable of safely making and breaking high inrush and continuous operating currents.
- Durable Construction: Built to withstand millions of mechanical and electrical operations.
Application Scenarios
Widely deployed in industrial manufacturing plants, motor control centers (MCCs), and commercial power distribution systems for controlling heavy machinery, pumps, and compressors.
Performance Parameters
- Continuous Current Rating: Rated for high continuous amperage at 600VAC (specific rating depends on exact frame size).
- Short Circuit Rating: Suitable for use on circuits capable of delivering high RMS symmetrical amperes when properly protected by fuses or circuit breakers.
Material Composition
Housed in a durable, flame-retardant thermoset plastic enclosure. Internal contacts utilize high-conductivity silver-cadmium oxide or silver-tin oxide pads designed to withstand extreme arcing temperatures.
Structural Characteristics
Standard NEMA form factor featuring a movable magnet, operating arm, return spring, and stationary/movable contact assemblies. Includes a molded cover for arc containment and personnel protection.
Working Principle
When the control coil is energized, it generates a magnetic field that pulls the movable armature, closing the main power contacts and allowing current to flow to the load. When de-energized, the return spring forces the contacts open.
Installation Requirements
Must be mounted on a sturdy vertical support. Ensure magnet mating surfaces are completely clean and free of dirt or foreign matter before installation. Electrical connections must comply with the National Electrical Code (NEC).
Usage Precautions
Always disconnect power before installing or servicing. Periodically inspect contacts for welding, pitting, or excessive wear. Never operate the contactor without proper overload protection.
