TB02 series temperature control switch thermal protector thermostat
TB02 series thermal protectors are small in size, sensitive in temperature and precise in protection. The lead temperature can be customized according to customer requirements. The structure is stable and is particularly suitable for various battery packs, battery protection boards, and products with small installation locations. Small in size, easy to install, fast in temperature sensing, stable in structure, lead temperature can be customized according to customer requirements, in line with environmental protection ROHS IS09001 standards, normally open or normally closed optional.
1 Product Application
TBO2 series temperature control switches are small in size, sensitive in temperature sensing, and provide accurate and reliable protection. They are particularly suitable for the safety protection of temperature sensing cables, battery protection boards, micromotors and transformers.
