Thermal overload protectors.
UB8P and UB81P self-hold thermal cut-out and thermal protectors are designed to provide overheat protection in high-voltage applications. With a 16 A capability, the new models are suitable for thermal overload protection in a broad range of applications, including space heaters, dishwashers, mixers, blenders, grinders, and other electronic appliances. The UB81P features a reinforced PBT enclosure for dust-proof applications; the UB8P has an exposed bi-metallic element for high accuracy and fast response to ambient air temperature. Both models incorporate a "self-hold" non-self resetting function that provides a high level of operational safety, especially in appliances with moving parts. The "self-hold" function ensures that after the element reaches its preset open temperature, the internal heater activates to maintain a self-regulating temperature, preventing the switch from resetting until the user disconnects the power.
Behind the Design: The bodies of these surface-mount devices are manufactured of phenolic resin and feature a patent-pending partition wall design that isolates the switch from the main body, This design effectively controls arcing that can cause a break in voltage contact (particularly in 250 V applications), ensuring continuous operation to setpoint.
