PTC-resistor relays type MS
PTC-Resistor-Relay Type MS(R)220KA
Single PTC-Circuit, ATEX-Approval according to Directive 2014/34/EU
•
PTC-relay for the application
as a protection device against
inadmissible heating up at elec-
trical equipment in areas with
explosive gases (zones 1 and
2) and areas with combustible
dust (21 and 22), e.g. for di-
rect temperature-monitoring of
explosion-proof motors EEx e
and EEx d.
1 PTC-resistor (thermistor) set, each 1...6 PTC-
sensors
short-circuit monitoring of sensor-circuit
output-relay with 1 or 2 change-over contacts (co)
2 LEDs for ON and ALARM
K-housing,vertically arranged terminals
housing 22.5 mm wide
assembly on DIN-rail or with 2 screws M4 (option)
