TB02-KA8D_ bb8d Smallest electronic Normally Open Thermal Protector switch

Product Item: TB02-KA8D_ bb8d Smallest electronic Normally Open Thermal Protector switch
Category: Miniature thermal protector
TB02B-B8D ultra-thin thermostat, size 13 × 5.4 × 2.4mm (length × width × thickness). 20 ° ~ 155 ° C Low Temperature Controller [Normally Closed / 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.
