Control cabinet thermostats mechanical, bimetal
Technical data
Application
Housing colour:
grey, like RAL 7035
Application scenarios include temperature monitoring in control cabinets, machines and housings.
Ambient temperature: Permissible atmospheric humidity: Max. switching voltage: Min. switching voltage: Min. switching current:
0 ... 60 °C
Max. 95% rel. humidity, non-condensing
230 VAC/50 Hz, 48 VDC 24 VAC/50 Hz, 24 VDC
The resistance of the contact transition results in a voltage drop across the contact. This can have a strong influence on very small switching signals.
