## Ordering information 

Example: 22 series 35 mm rail mount relay, 1 NO (SPST-NO) 20 A contact, coil rated 24 V DC, contact material AgSnO2.

Series Type 2 = 35 mm rail (EN 60715) mount No. of poles 1 = 1 NO (SPST-NO) 2 = 2 NO (DPST-NO) 3 = 1 NO + 1 NC (SPST-NO + SPST-NC) 4 = 2 NC (DPST-NC) 

Contact material 4 = AgSnO2 Coil voltage See coil specifications Coil version 8 = AC (50/60 Hz) 9 = DC
