CL00A310T1 GE 3-Pole Power Contactor
Product Dimensions：
Product Description (Detailed Explanation)
The CL00A310T1 is a compact alternating current (AC) contactor used primarily for motor control applications. The “310” designation indicates it features 3 main power poles and 1 built-in auxiliary contact (Normally Open).
This specific model is designed for AC-3 applications (squirrel-cage motors), providing a robust mechanical life and high switching frequency. Its modular design allows for the easy addition of front-mounted or side-mounted auxiliary contact blocks (like the LM10) and pneumatic timers. The “T1” suffix typically refers to the specific coil voltage rating, commonly used for 24V AC or specialized industrial control voltages.

Product Advantages (Key Benefits)
-
Compact Footprint: High performance in a small frame size, allowing for high-density installation in control cabinets.
-
Dual Mounting Capability: Can be snapped onto a standard 35mm DIN rail for quick installation or screwed directly to a mounting plate for high-vibration environments.
-
Safety & Protection: Features “finger-safe” terminals (IP20) to prevent accidental contact with live parts during maintenance.
-
High Reliability: Optimized contact materials ensure minimal arcing and long contact life, even under heavy inductive motor loads.
-
Easy Accessories: Supports a wide range of clip-on accessories, including thermal overload relays, surge suppressors, and additional auxiliary contacts.
Precautions (Important Notes)
-
Coil Voltage Verification: Always verify that the control circuit voltage matches the “T1” coil rating before energizing. Applying 110V or 230V to a 24V coil will cause immediate failure and potential fire hazard.
-
Overload Protection: This contactor provides switching only. It must be paired with a thermal or electronic overload relay (such as the GE MT series) to protect the motor from burnout.
-
Arcing Distance: Maintain the manufacturer-recommended clearance distances above and below the unit to allow for proper heat dissipation and safe arc venting.
-
Wiring Tightness: Ensure all power terminals are tightened to the specified torque. Loose connections on high-current poles can lead to localized overheating and terminal melting.
Product Applications (Typical Use Cases)
-
Small Motor Control: Starting and stopping of 3-phase motors up to 4kW (fans, pumps, small conveyors).
-
Heating Loads: Switching resistive heating elements (AC-1) in industrial ovens or environmental chambers.
-
Automation Panels: Acts as the primary interface between low-power PLC outputs and high-power mechanical loads.
-
Lighting Systems: Controlling large banks of industrial discharge lamps or LED arrays.
-
Safety Interlocks: Used in conjunction with safety relays to disconnect power to hazardous machinery upon an emergency stop command.
