An alarm is stored until a reset is made. ATEX-approval according to directive 2014/34/EU Electronic reclosing lock (dis- connectable) Integrated RESET-button Link for external reset Automatic reset at voltage recovery Option: other supply-voltages PTC-relay for the application as a protection device against inad- missible heating up at electrical equipment in areas with explosi- ve gases (zones 0, 1 and 2) and in areas with combustible dust (zones 20, 21 and 22), e.g. for direct monitoring in explosion- protected areas where intrinsic safety class "i" is afforded. PTC-Sensors (Thermistors) of intrinsic safety class "i" can be connected directly. The sensors may be placed in the potentially explosive athmosphere, e.g. for mechanical explosion-protection at bearings.The relay itself may not be installed in the potentially explosive atmospheres. 2016-11-28 MS(R)220Vi Kaltleiter-Relais T2T1 A2A1 12 11 14.com PTC Ue = 250 V Ie = 3 A AC 15 ~+ ~ Us NC 24 21 22 NC Y1 Y2 PA ON ALARM Reset 1 … 6 PTC Ex M F1-F3 N Us DC + AC ~ Ex = area of potentially explosive atmosphere PTC = Thermistor sensor Us = supply voltage S1 = external reset S2 = pushbutton OFF S3 = pushbutton ON H1 = Trip alarm F1-F4 = fuses K1 = contactor 1) only MSR 2) twisted lines Part number: T222185 AC 220-240 V Part numbers: T222195 AC 220-240 V T222191 AC/DC 24 V MS220Vi MSR220Vi
