Description

The A-B 1336-TR-SP4A/A is a Thermistor Kit designed for use with Allen-Bradley PLUS, PLUS II, FORCE, and IMPACT drives with a voltage rating of 230 Volts. It is a Level 3 spare part that falls under the discrete components category.

Key Features:

  • Thermistor Type: This kit utilizes a negative temperature coefficient (NTC) thermistor to sense the temperature of the drive’s heat sink.
  • Temperature Monitoring: The thermistor’s resistance decreases as temperature increases. This change in resistance is monitored by the drive to protect the drive from overheating.
  • Overheating Protection: If the thermistor detects excessive heat, the drive will take protective actions, such as reducing power output or shutting down completely, to prevent damage.

Compatibility:

  • Drive Series: PLUS, PLUS II, FORCE, and IMPACT
  • Voltage Rating: 230 Volts
  • Frame Size: E frame
  • Horsepower Ratings: 75 HP, 100 HP, and 125 HP

Part Number Breakdown:

  • A-B: This likely indicates the manufacturer, Allen-Bradley (A-B is a common abbreviation).
  • 1336: This could be a series or product code related to the thermistor kit.
  • TR: This might stand for “Thermistor” or “Temperature Related”.
  • SP4A/A: This could be a specific revision or variant of the thermistor kit.

Applications:

  • Variable-speed drives (VFDs) for controlling the speed of AC motors in industrial applications like:
    • Conveyor systems
    • Pumps and fans
    • Machine tools
    • HVAC systems
