UB8P Model
FEATURES
Models UB8P (exposed model - shown above) and UB81P
(enclosed model) Self-Hold Thermal Cut-Out and Thermal
Protectors are designed to provide overheat protection in high
voltage applications. With a high 16 Amp capability, the new
models are well suited for thermal overload protection in a
broad range of applications.
The body of these surface mount devices are manufactured of
phenolic resin and feature a new patent pending partition wall
design that isolates the switch from the main body.
design effectively controls arcing that can cause a break in
voltage contact (particularly in 250V applications), ensuring
continuous operation to setpoint.
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 pre-set
open temperature, the internal heater activates to maintain
a self-regulating temperature, preventing the switch from
resetting until the user disconnects the power.
