Description
GE CR115E724112
Technical Specifications
- Series: GE CR115.
- Part Number: CR115E724112.
- Type: Electromechanical Control Relay.
- Coil Voltage: Specific to part suffix (typically 24VDC, 120VAC, etc.).
Functional Features
- High Inrush Capability: Designed to handle motor starting currents without contact welding.
- Mechanical Interlocks: Optional mechanical latching or interlocking features.
- Long Mechanical Life: Rated for millions of operations.
Application Scenarios
Motor control centers, conveyor systems, HVAC controls, and industrial automation panels.
Performance Parameters
- Contact Rating: Rated for specific AC/DC loads (e.g., 10A at 600VAC).
- Dielectric Strength: High isolation between coil and contacts.
- Operate/Release Time: Fast response for precise control logic.
Material Composition
Silver-cadmium oxide or silver-tin oxide contacts for arc suppression. Phenolic or thermoplastic housing with copper coil windings.
Structural Characteristics
Plug-in or panel-mount configuration with octal or blade terminals. Transparent cover option for visual contact inspection.
Working Principle
When the coil is energized, it generates a magnetic field that pulls the armature, mechanically closing or opening the contacts to control the external load circuit.
Installation Requirements
Mount vertically or horizontally as specified. Ensure adequate clearance for heat dissipation and arc quenching.
Usage Precautions
Do not exceed the rated contact load. Use appropriate surge suppression (RC snubbers) across DC coils or inductive loads.
