GE IC2812B107DA3 Field Contactor
GE IC2812B107DA3
Overview
GE IC2812B107DA3 is a 600 V class Motor Field Contactor manufactured by General Electric (GE), with a rated current of approximately 200 A. It is suitable for starting, stopping, and protecting AC motors. This contactor belongs to GE’s IC series of high-voltage electrical components, featuring a reliable mechanical structure and excellent electrical performance. It is widely used in industrial power distribution and automation systems.
Main Specifications
- Rated Voltage: 600 V AC (rated operating voltage)
- Rated Current: 200 A (normal operating current)
- Pole Number: 3 poles (compatible with three-phase motors)
- Contact Configuration: Normally Open (NO) contacts, with auxiliary contacts for signal feedback
- Mechanical Life: ≥ 100,000 operations
- Electrical Life: ≥ 50,000 operations
- Protection Class: IP 20 (for indoor installation)
Product Features
- High Reliability: Adopts high-temperature and corrosion-resistant alloy materials to ensure long-term stable operation in harsh environments.
- Fast Breaking: Short breaking time, which can effectively suppress electric arcs and protect motors and circuits.
- Modular Design: Standardized size, facilitating unified layout and replacement in power distribution cabinets.
- Auxiliary Contacts: Provides additional normally open/normally closed auxiliary contacts, enabling easy linkage with control systems such as PLCs and relays.
- Easy Maintenance: Simple structure and convenient disassembly and assembly, reducing maintenance costs.
Structure and Composition
- Main Contact Assembly: Includes main contact base, spring, and contact spring mechanism, responsible for on-off of main current.
- Auxiliary Contact Assembly: Provides signal feedback, often used for status indication or control circuits.
- Coil (Coil Box): Generates magnetic field to drive the main contacts to act after being energized, with a rated coil voltage of 230 V AC.
- Enclosure: Metal enclosure provides mechanical protection and electrical insulation.
- Mounting Flange: Used for fixing on power distribution cabinets or panels, achieving stable installation with bolts.
Typical Application Fields
- Industrial Automation: Motor control for CNC machine tools, packaging machinery, and conveyor systems.
- Power Distribution: Motor protection and control for power distribution cabinets and substation.
- Petroleum and Chemical Industry: Starting and stopping of large motors such as pumps and compressors.
- Building Facilities: Driving of high-power motors for air conditioning and ventilation systems.
- Mining Machinery: Motor control for heavy-duty equipment such as hoists and crushers.
Installation and Maintenance Points
Installation
- Confirm that the installation space in the power distribution cabinet meets the size of the contactor (standard 3-pole module).
- Use dedicated bolts to fix the flange on the power distribution cabinet or panel, ensuring the contactor is placed horizontally.
- Correctly connect the main circuit, auxiliary contacts, and coil power supply according to the wiring diagram, paying attention to phase sequence and grounding.
- Check that the coil voltage matches the power supply voltage to avoid coil damage caused by overvoltage or undervoltage.
Commissioning
- Before energization, check that all wiring is secure, without short circuits or incorrect connections.
- First, test the coil energization alone to see if it can pull in normally, then check the closing and breaking of the main contacts.
- Use an ammeter to monitor the starting current and ensure it does not exceed the rated value.
Daily Maintenance
- Regularly check the wear of contacts and replace the contact assembly if necessary.
- Remove dust and corrosives inside the enclosure to maintain good heat dissipation.
- Check the coil resistance to prevent overheating of the coil due to aging.
- Conduct functional tests on the auxiliary contacts to ensure accurate signal feedback.
Troubleshooting
- Failure to Pull In: Check the coil power supply, coil resistance, and terminal blocks; confirm that the coil is not burned out.
- Contacts Fail to Break: May be due to contact wear or spring failure, requiring replacement of the main contact assembly.
- Abnormal Noise or Heating: Check if the load exceeds the rated current or if there is looseness inside the contactor.
