Safety thermal cut-out 89.00
Application
For heat generators with tempertures up to 350°CFeatures
Electro-mechanical safety thermal cut-out (STB) with capillary sensor approved to DIN EN 14597 and EN60730-1/2-9- If cut-out temperature is exceeded, circuit switches to OFFor changeover and stays in thisposition
- Fail safe design: Expansion liquid loss results in opening of contact C-1
- Manuell resetting after sensing element has cooled by at least 10K
- Single-pole micro switch with on/off or change-over switch
- Time factor of sensing element better than DIN EN 14597
- Temperature compensated switching head
- Operation type 2.B.H.K.L.P (EN60730)
- RoHS-conform
- DIN CERTCO Registernumber: TR1107
