Limit value switch for temperature (NTC thermistor)
Limit value switches of type RH5 monitor electrical measured variables. The integrated relay switches when the actual value present reaches the set target value. Furthermore, limit value switches of this type are equipped with sensor monitoring for short circuits and wire breaks. Its compact and robust design, as well as the relevant shipbuilding approvals, make this product ideal for marine applications.
