Features
●
Small and Insulation Type
TCO is compact and insulated, featuring quick temperature response, and mountable in a small space without
insulation or protection.
●
High Reliability
TCO opens reliably when the equipment becomes abnormal, and is not resettable.
●
Solid Structure
Unique formed lead provides reliable TCO connection and provides easy assembly handling. (Axial lead type only)
●
Thin Type
Thick is less than 0.8 mm (MP and ML series), available for spot welding (MP, ML and MU series)

Functioning Temperature (Fusing-off temperature)
The functioning temperature at which a TCO changes its state of conductivity to open circuit in the ambient air oven which increases
temperature by 1 °C per minute and with loading the detective current 0.1 A or less.
Maximum Operating Temperature.
The maximum temperature at which a TCO can be maintained while conducting rated current for 1000 h.
For details please refer to specification.
Holding Temperature (Th)
The maximum temperature at which a TCO can be maintained while conducting rated current for 168 h which will not cause a change in
state of conductivity to open circuit.
Maximum Temperature Limit (Tm)
The maximum temperature at which a TCO can maintains its mechanical and electrical properties with out closing again for 10
minutes after a TCO has changed its state of conductivity.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
