Thermal Cut-Offs
SDJ1/SDJ2
2007/June
GENERAL
Our Thermal Cut-Offs (Organic Thermal Element
Type) are used to prevent fires caused by
abnormal heat generation from circuits and other
heat producing electrical products. They are a
non-resettable thermal fuse which open electrical
contacts when temperatures exceed the specified
level.
APPLICATIONS
• Electric home appliances and heating devices
• Coil-winding products and power supplies
• Office equipment and telecommunication devices
• Automobiles & other electronic components
OPERATING PRINCIPLE
When the ambient temperature rises to the function-
ing temperature, the thermal element melts and the
springs move the contact away and open the circuit
permanently.
