H101(710°C / 1,328°F)

H101
> PDF Tech Info, Schematics and More

Features
1. Unique fuse of 710°C/550°C.
2. External dimensions are the same for all H101 models.
3. The fuse is housed in a ceramic cylinder case.

Precautions for handling
1. When the current exceeds the rated value, it will activate at a lower temperature than the fusing preset temperature. Check once again that the current is not exceeding the switching capacity.

2. Unexpected force or shock during transportation or mounting may cause breakage of the temperature fuse. Furthermore, if the ambient temperature goes up, it may lead to an accidental fusing at a lower
temperature. So, be careful regarding the ambient temperature.

3. Keep the temperature sensor (protection tube) horizontal or pointing downward (lead wire will be at the
top) when in use. If it is used with the temperature sensor up, it may cause a malfunction.

4. Do not use in an environment where vibration or shock is constantly applied.

5. Watch for other heat sources, and try to avoid thermal interference. Be careful of fuse malfunction due to unexpected other heat sources.

Applications High Temperature Equipment, Wave Soldering, Commercial Ovens, Laboratory Equipment, Food Service

> Technical Data
Type	Fusing preset temperature	Switching power supply voltage	Switching capacity	Dialectric strength (after fusing)	Lead wire
H101	710°C +/- 10°C	Commonly used for 200/200V	710°C/200VAC 2A (resistance load)	1200VAC/sec (between terminals)	1.25mm Nickel lead wire

CAUTION
1. For storage, avoid high temperature places.
2. Ceramic protection cylinders tends to crack.
So, be careful when handling.
3. Do not use the fuse without the protection tube.
4. Keep the load current within the rated value.

In principle, the temperature fuse is meant to be used as a fail safe measure. The correct system design is such that a thermostat is used for temperature control and a temperature fuse activates when the thermostat is broken.
