NFZ..K contactor relays - with Push-in Spring terminals
24 V DC operated designed for PLC

NFZ contactor relays are used for switching auxiliary and control circuits.
These contactor relays are of the block type design with 4 poles or 8 poles (with a permanently
03
fixed 4-pole auxiliary contact block).
• contactor relays have mechanically linked auxiliary contact elements (side-marked symbol)
• control circuit: 24 V DC operated with electronic coil interface allowing low holding consumption
up to 1.7 W and reduced panel energy consumption
- allow direct control by PLC-output ≥ 250 mA 24 V DC
1SBC101649V0014 • built-in surge suppression
- very distinct closing and opening

• add-on auxiliary contact blocks for front or side mounting and a wide range of accessories.
