The IMO U12/16E18-MC Thermal Overload Relay is designed to provide reliable protection for electric motors against overheating due to overload conditions. By monitoring the motor's current, it ensures that any excessive current draw is detected promptly, thereby preventing potential damage to the motor. This model is compatible with CR01C-CR12C (MC10 to MC22) Contactors in the IMO Range.

Key Features:

• Adjustable Current Settings: Allows for precise calibration to match the motor's full-load current, ensuring optimal protection.
• Phase Failure Sensitivity: Detects phase loss conditions, offering protection against single-phase running, which can cause motor damage.
• Automatic and Manual Reset Options: Provides flexibility in operation, allowing for automatic resetting after a trip or manual intervention as required.
• Compact Design: Facilitates easy integration into motor control circuits without requiring significant space.
• Auxiliary Contacts: Equipped with 1 Normally Open (NO) and 1 Normally Closed (NC) contact, facilitating integration into control circuits for signaling and interlocking purposes.

Specifications:

• Current Range:
  • 13-18A – This range applies when the motor is running in a direct-on-line (DOL) connection or a standard operation mode.
  • YD 23-31A – This range is applicable when the motor is running in a star-delta (YD) starting configuration, which temporarily reduces the starting current.
• Trip Class: Class 10, suitable for general motor protection applications.
• Compatibility: This model is compatible with CR01C-CR12C (MC10 to MC22) IMO Pacific Contactors. Designed to be directly mounted onto compatible contactors for streamlined installation.
• Standards Compliance: Meets international standards for motor protection, ensuring reliable performance.

Applications:

• Industrial Machinery: Protects motors in manufacturing equipment from damage due to overloads.
• HVAC Systems: Ensures the longevity of motors in heating, ventilation, and air conditioning units by preventing overheating.
• Pumping Stations: Safeguards pump motors against conditions that could lead to excessive current draw and potential failure.

The IMO U12/16E18-MC Thermal Overload Relay offers dependable motor protection by detecting and responding to overload conditions, thereby enhancing the longevity and reliability of motor-driven systems across various industrial applications.
