Product Description:TLY-A220T-HJ62AN

The Allen-Bradley TLY-A220T-HJ62AN is a thermal overload relay designed for the protection of motor-driven equipment from damage due to overload conditions. It is part of the TLY series, a line of relays known for providing reliable thermal protection for industrial motors, ensuring that they do not overheat due to excessive current. The TLY-A220T-HJ62AN specifically is designed for use with motors rated around 22 amps, but its settings can be adjusted to match the specific motor requirements.

This relay detects when the motor current exceeds safe limits for an extended period, causing a thermal buildup that could lead to motor damage. Once the relay detects an overload, it will trip and disconnect the motor from the circuit, preventing damage. After a cool-down period, the relay can be reset, either manually or automatically, depending on the configuration. The TLY-A220T-HJ62AN is typically used in a variety of industrial applications such as pumps, conveyors, HVAC systems, and manufacturing equipment where reliable motor protection is critical for operational safety and longevity.

The relay also includes features like visual trip indication, adjustable trip settings, and temperature compensation to ensure it performs reliably in varying environmental conditions.

Features:TLY-A220T-HJ62AN

• Motor Overload Protection:

  • The primary function of the TLY-A220T-HJ62AN is to provide thermal protection for motor-driven equipment by detecting overload conditions (excess current) and disconnecting the motor from the power supply to prevent overheating and potential motor damage.

• Adjustable Overload Setting:

  • The relay features an adjustable overload current setting to match the specific current rating of the motor. The TLY-A220T-HJ62AN is rated for motors around 22A, but the current adjustment range allows for fine-tuning protection to accommodate different motor sizes and load conditions.

• Trip Class Selection:

  • This relay typically offers adjustable trip classes (e.g., Class 10, Class 20, or Class 30), which define the time-to-trip characteristic for the relay. A Class 10 relay will trip quickly (within 10 seconds) for a severe overload, while Class 20 or 30 will allow for a longer time-to-trip for less severe overloads, providing protection for motors with more gradual overload conditions.

• Temperature Compensation:

  • The TLY series relays come with temperature compensation features that adjust the trip curve to account for ambient temperature fluctuations. This ensures that the relay functions properly in varying environmental conditions, helping prevent unnecessary trips in hot or cold environments.

Customization:TLY-A220T-HJ62AN

Adjustable Overload Current Setting

• Customizable Current Rating:
  • The TLY-A220T-HJ62AN offers an adjustable current range (typically between 13 A to 22 A), allowing you to set the relay to protect motors that have different rated currents. You can fine-tune the current protection setting to match the motor’s rated full-load current, ensuring optimal protection.
  • The adjustment can be done via a dial or knob on the relay, offering flexibility for various motor sizes and load conditions.

2. Selectable Trip Class

• Adjustable Trip Characteristics:
  • The trip class setting is customizable to select different trip times for different types of motor protection needs. You can select a Class 10, Class 20, or Class 30 trip characteristic based on the application:
    • Class 10: Faster tripping for motors that need quicker overload protection.
    • Class 20/30: Slower tripping for motors that are more tolerant of short-term overloads or where gradual overloads are more likely.
  • This option allows you to tailor the response time of the relay to better suit the operational requirements of the motor and machinery.

3. Reset Type Selection

• Manual or Automatic Reset:
  • The reset function can often be customized to either manual reset or automatic reset based on the application:
    • Manual Reset: Requires the operator to reset the relay after it trips, providing more control over when the motor is allowed to restart.
    • Automatic Reset: The relay can be configured to automatically reset after the overload condition is cleared and the motor has cooled down to a safe operating temperature.
  • Depending on the system's operational requirements, this choice can help streamline operations or provide a safety mechanism.

4. Ambient Temperature Compensation

• Temperature Adjustment:
  • The TLY series includes temperature compensation to adjust the trip time and settings based on ambient temperature. This ensures the relay provides consistent protection regardless of temperature fluctuations in the environment.
  • Custom Calibration for Different Environments: If your application operates in environments with extreme temperature conditions (hot or cold), this feature helps ensure the relay trips appropriately based on actual operating conditions, rather than relying on static temperature-dependent settings.

5. Auxiliary Contacts and Accessories

• Auxiliary Contacts:
  • You can customize the relay with auxiliary contacts that allow integration with other control systems for signaling or remote monitoring. These contacts can be used to indicate a trip condition or to send signals to other parts of the system (e.g., alarms or control circuits).
  • Auxiliary contacts typically provide NO (Normally Open) or NC (Normally Closed) configurations for integration into the broader motor protection system.
• Overload Trip Indication:
  • For applications requiring visual or remote trip indication, you can choose to add status indicators or alarm contacts that signal when the relay has tripped. These can be connected to external warning systems or displayed on a central control panel.
• Thermal Memory Option:
  • Some applications may require a thermal memory feature, which retains the relay’s overload condition history to help diagnose motor faults or protect against consecutive overloads. This option is available with some TLY series models and can be particularly useful for logging faults in mission-critical applications.

6. Mounting and Installation

• DIN Rail Mounting:
  • The TLY-A220T-HJ62AN typically comes with DIN rail mounting, but you can customize the installation setup with various DIN rail options and accessories for ease of integration into different types of control panels or enclosures.

  • The relay supports a range of wire sizes for the motor connections. Depending on the application and system design, you can customize the type of wire or cable you use with the relay, ensuring compatibility with your existing electrical setup.

7. Custom Trip Settings via Firmware

• Advanced Models: For more advanced versions of overload relays, customization can be done via firmware settings or communication interfaces. Some models support programming options where specific trip curves or custom delay times can be set through a communication network (e.g., via Ethernet/IP, Modbus, or other protocols). This is typically available on more sophisticated overload relays, which may be part of the TLY series for integration into automation systems.

8. Integrated Circuit Breaker or Contactor

• In some applications, the overload relay can be integrated with a motor starter or circuit breaker as part of a custom motor protection solution. This ensures that motor protection is combined with short-circuit protection in a seamless package, offering both thermal and electrical fault protection.

9. Enhanced Sensitivity or Delay for Special Applications

• For certain critical applications (e.g., high torque start-up motors or motors in systems with fluctuating loads), you can choose custom delay options to prevent unnecessary trips during short-term overloads. This can be beneficial in applications where motors are intentionally subjected to higher starting currents for brief periods, such as in cranes, elevators, and hoists.
