Elmwood D Series

Elmwood D Series are based on reliable one-shot operation and protect electrical appliance against overheating.

Thermal Cut Offs (TCO) responds to temperature by interrupting an electrical circuit when the operating and /or environmental temperature exceeds the thermal rating of the fuse. This is accomplished when the organic pellet experience a phase change, allowing the spring activated contacts to permanently open the circuit. Once activated the electrical circuit remain permanently open.

Tf (FUNCTIONING OPEN TEMPERATURE)
The maximum temperature at which the thermal cut offs changes its state of conductivity
to open circuit with detection current as the only load.

Th (HOLDING TEMPERATURE)
The maximum temperature at which,when applying no electrical load to the thermal cut offs,
the state of conductivity will not change during a period of 168 hours.

Tm (MAXIMUM OVERSHOOT TEMPERATURE)
The maximum temperature of thermal cut offs, having changed its state of conductivity, can be maintained for 10 minutes
during which its mechanical and electrical properties will not be impaired.
