The TB02/TB05 Bimetallic Thermal Switch is an advanced circuit protection device engineered to automatically interrupt power during overheating conditions. Utilizing a snap-action bimetallic disc mechanism, this thermal protector offers precise temperature activation to safeguard critical components in motors, compressors, transformers, and heating systems across HVAC, commercial appliances, and industrial applications.

• ±3°C activation accuracy prevents thermal damage through reliable snap-action response
• SPDT (Single Pole Double Throw) contacts with silver alloy plating ensure consistent switching

• Stainless steel actuator + ceramic terminal base
• Hermetically sealed contacts resist humidity, vibration, and oxidation

• Pre-certified to UL, CE, and RoHS standards for fast market deployment

• Compact form factor supports both vertical and horizontal mounting in confined spaces
