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)
