Surface-mounting thermostats, type series AMTHF
with 2, 3 or 4 1-pole snap switches
Special features
• Protection rating IP 54
• tested as per DIN EN 14597 (replacement for DIN 3440)
Type AMTHFs-13
Brief description
Add-on thermostats are used to control and monitor thermal processes. The devices of type
series AMTHF are available with 2, 3 or 4 switching stages as temperature controllers (TR) and
temperature monitors (TW). The sequential gap in Kelvin for the individual circuit stages is factory-set fixed as per customer request. Add-on thermostats operate according to the fluid expansion principle, a microswitch is used as an electrical switching element.
Page 1/8
Switching function
Temperature controller (TR) and temperature monitor (TW)
If the temperature exceeds the setpoint value set on the temperature probe, the microswitch
will be tripped by the transmission mechanics and the current circuit opened or closed. The microswitch is reset to its original status once the setpoint value set is gone below (by the hysteresis).
