Strukturovaná kabeláž a kabeláž pro datová centra
Metz, TMR-E12 without error memory, 24 V ACDC, 2 changeover contacts
| Kód: | 1103151322 |
- The thermistor relay is used as protection relay for motors against thermal overload (inadmissible heating)
- This heating might be caused by mechanical overload on the shaft or when operating the motor with inadmissible voltages
- A PTC thermistor is used as sensor

- The thermistor relay is used as protection relay for motors against thermal overload (inadmissible heating)
- This heating might be caused by mechanical overload on the shaft or when operating the motor with inadmissible voltages
- A PTC thermistor is used as sensor
- It should be mounted to the part of the motor that heats most in case of overload (e.g. integrated in motor winding)
- The device can also be used for motors with integrated thermo switch
- Variants:
- 230 V AC or 24 V AC/DC
- 1 or 2 changeover contacts (1 or 2 DPST)
