TB02-BB8D Smallest Battery Thermal switch

The TB02 series thermal protector is a miniature thermal protector independently developed and produced by YAXUN, and has won the world record certificate. It is divided into two forms: pure temperature type and overheating and overcurrent dual protection type. It has high reliability and repeatability. The steel structure bracket makes the performance more stable, and the automatic temperature calibration process makes it have high temperature control accuracy, sensitive temperature sensing, and compact appearance. Suitable for applications with tight mounting on or within windings, custom processing can be provided according to customer requirements. Widely used in batteries, tubular motors, lighting, трансформаторы, моторы, water pumps, smart homes, fire cables and medical equipment.

TB02B-BB8D ultra-thin thermostat, size 13 × 5.4 × 2.4mm (length × width × thickness). 20 ° ~ 155 ° C Low Temperature Controller [Нормально закрытый / Normally Open Type]
The use of a bimetal with a certain geometry does not require an auxiliary mechanism.
Only the bimetallic piece's own temperature and current and heat effect can make the state of the bimetallic component change rapidly, and directly drive the contacts to realize automatic cut-off and connection of the circuit. Overheating and overload protection.
It has the advantages of small size and high sensitivity.
