China Mini Thermostat Temperature Regulator with Ce RoHS Certificates

> Large setting range
> Small size
> Simple to mount
> High switching performance

DMO 1140: Thermostat (normally closed); contact breaker for regulating heaters. The contact opens when temperature
is rising
.
DMS 1141: Thermostat (normally open); contact maker for regulating of filter fans and heat exchangers or for switching
signal devises when temperature limit has been exceeded. The contact closes when temperature is rising
.
