NFZ 4-pole contactor relays

AC / DC operated - low consumption

Description
NFZ contactor relays are used for switching auxiliary and control circuits.
These contactor relays are of the block type design with:
– 4 poles. Contactor relays have mechanically linked auxiliary contact elements (side-marked symbol)
1SBC101104F0014 – control circuit: AC or DC operated with electronic coil interface accepting a wide control voltage range
(e.g. 100...250 V AC and DC)
- can manage large control voltage variations
- only 4 control voltage ranges covering 24...250 V 50/60 Hz and 12...250 V DC
NFZ22E - allow direct control by PLC-output ≥ 24 V DC 500 mA
- reduced panel energy consumption
- very distinct closing and opening
- can withstand short voltage dips and voltage sags (SEMI F47-0706 conditions of use on request).
– built-in surge suppression
– add-on auxiliary contact blocks for front or side mounting and a wide range of accessories.

Note: Only NFZ contactor relays with DC control voltage 12...20 V DC need to respect the connection polarities indicated close to the
coil terminals: A1+ for the positive pole and A2- for the negative pole.
