TB02/TB05 Bimetallic Thermal Switch High Precision Thermal Protector for HVAC, Appliances & Industrial Equipment

The TB02/TB05 Bimetallic Temperature Control Switch is a precision-engineered thermal protection device designed for automatic circuit interruption in overheating scenarios. Utilizing a bimetallic disc mechanism, this switch activates at preset temperature thresholds (customizable from 40°C to 160°C) to safeguard motors, compressors, transformers, and heating elements in HVAC systems, commercial appliances, and industrial machinery. Featuring SPDT (Single Pole Double Throw) contacts with silver alloy plating, it ensures reliable switching under 10A/250VAC loads while complying with UL and RoHS safety standards. Compact housing allows vertical/horizontal mounting in space-constrained environments.

Product feature:

• Fail-Safe Thermal Protection
  Dual metal snap-action technology triggers within ±3°C accuracy, preventing equipment damage from thermal runaway.
