ZIEHL industrie-elektronik, 74523 Schwäbisch Hall, Germany, +49 791 504-0, info@ziehl.de, www.ziehl.de PTC-resistor relays type MS PTC-relay for the application as a protection device against inad- missible heating up at electrical equipment in areas with explo - sive gases (zones 1 and 2) and areas with combustible dust (21 an 22), e.g. for direct temperatu- re-monitoring of explosion-proof motors EEx e and EEx d. This compact version is espe- cially suitable for mounting in fuse-boxes or power-distribution panels. ATEX-approval according to directice 2014/34/EU SIL 1 nach IEC 61508 PL c nach ISO 13849 PTC-Resistor-Relay Type MS(R)220VA Single PTC-Circuit, Atex-Approval according to Directive 2014/34/EU 14 11 12 NC Y1 Y2 MS(R) 220 VA Schwäb.Hall www.ziehl.de Ue = 250 V Ie = 3 A AC 15 NC NC Kaltleiter- Relais Reset ~/+ ~/– ON ALARM Us DC + AC ~ 1 … 6 PTC M 3~ F1-F3F4 N Technical Data Rated supply-voltageUs connectable PTC-resistors switching point output relay type of contaxt test conditions rated ambient temperature dimensions (h x w x d) attachment protection housing/terminals weight AC 220 - 240 V ± 10 % 50/60 Hz ≤ 2 VA AC/DC 24 V, AC ± 10 % DC 21- 30 V < 2 VA, without potential separation 1...6 in series according toDIN 44081 or 44082 < 4000 Ω 1 change-over contact (co) type 2 see "general technical information" see "general technical information" -20...+55 °C design V2: 90 x 35 x 58 [mm] on 35 mm DIN-rail or with 2 screws M4 IP 30 / IP 20 app. 120 g Same execution as MS220VA, additionally with electronic reclo- sing lock.
