Minimelt Plus
Thermal Link
Tmax 206°C / 229°C / 260°C / 298°C / 318°C / Imax15A / very short reaction time / orientation independent mounting / temperature resistant ceramic housing / standard terminals
Properly installed, the thermal link type 155 431 may be used for example in coffeemakers, irons, fryers etc, and wherever a fi xed temperature may not be exceeded.
The thermal link has a melt solder insert in the mounting plate which is in direct thermal contact with the surface that is to be monitored. When the preset temperature is reached, the solder melts causing a pin to move which results in the electrical contacts opening. Resetting is not possible.

Details
Technical Data
fixed Thermal Link
The thermal link ’Minimelt Plus’ Type 155 431 is approved according to DIN VDE 0821 EN 60691 and is suitable for:
| Ambient conditions: | Temperature fuse for use under usual atmospheric conditions |
| Circuit conditions: | Termal fuse for use in ohmic circuits. |
| Comparative tracking index: | CTI > 250V |
Characteristic values | VDE | *) cURus |
|---|---|---|
| Nominal current | Ir 13,5 A | 15 A |
| Cut-off current | Ib 20,3 A | 22,5 A |
| Short-term overload current | Ip 203 A | 225 A |
| Nominal voltage | Ur 230 V | 120 V |
| *) cURus = UL / CSA |
Special information
The thermal link should neither be coated or potted nor be used in impregnated windings. The thermal link is a non repairable part. In case of replacement an equivalent thermal link with same type number and rated functional temperature Tf should be used, mounted in exactly the same way. Th does not relate to the ambient temperature only but to the temperature measured at the mounting plate close to the thermal element.
Characteristic temperatures
Tf ... Nominal temperature
Th ... Continuous operating temperature in accordance with DIN EN 60691 (measured at base plate near the solder insert)
Tm ... Max. limit temperature

Applications
Properly installed, the thermal link type 155 431 may be used for example in coffeemakers, irons, fryers etc, and wherever a fi xed temperature may not be exceeded.
Structure and mode of operation
The thermal link has a melt solder insert in the mounting plate which is in direct thermal contact with the surface that is to be monitored. When the preset temperature is reached, the solder melts causing a pin to move which results in the electrical contacts opening. Resetting is not possible.
