PTC-Thermistor-Relay Type MSR220KA
Do you have a question?
PTC-relay for the application as a protection device against inadmissible heating up at electrical equipment in areas with explosive gases (zones 1 and 2) and areas with combustible dust (21 and 22), e.g. for direct temperature-monitoring of explosion-proof motors EEx e and EEx d. Vertically arranged terminals. Each terminal remains accessible even if all others are already occupied.
