The UB8P and UB81P Self-Hold Thermal Cut-Out and Thermal Protectors provide overheat protection in high-voltage applications.
The phenolic resin bodies of these surface-mount devices feature a partition wall that isolates the switch from the main body. This controls arcing that can cause a break in voltage contact (particularly in 250-V applications), ensuring continuous operation to setpoint. The UB81P features a reinforced PBT enclosure for dustproof applications, while the UB8P has an exposed bimetallic element for high accuracy and fast response to ambient air temperature. They have a UL rating of 16 A at 125 Vac and a European rating of 10 A at 250 Vac. The devices measure 31.5 6.5 4.2 mm and operate from 75 to 145°C.
