Farnell provides temperature monitoring relays designed to protect equipment from overheating. With adjustable trip points and fast response times, these relays prevent thermal damage and improve system longevity.

Temperature monitoring relays measure the temperature of electrical equipment and surrounding environments. When a set threshold is exceeded, the relay triggers cooling or system shutdown to prevent overheating.

Key Features:

  • Adjustable temperature thresholds for precise protection.
  • Fast response time to prevent thermal damage.
  • Compatible with thermocouples and RTDs.

Applications:

  • HVAC Systems – Protect compressors and heating elements from overheating.
  • Industrial Motors – Prevent motor damage due to high temperatures.
  • Renewable Energy – Ensure stable operation in solar and wind systems.
