NFZ 8-pole contactor relays
AC / DC operated for specific applications

NFZ contactor relays are used for switching auxiliary and control circuits.
These contactor relays are of the block type design with:
03
• 8 poles with a permanently fixed 4-pole auxiliary contact block. Contactor relays have mechanically
linked auxiliary contact elements (side-marked symbol) except for NFZ33/11 and NFZ51/11 variants
• overlapping of lagging / leading contacts for NFZ33/11 and NFZ51/11 variants
• control circuit: AC or DC operated with electronic coil interface accepting a wide control voltage
1SBC101029V0014 - can manage large control voltage variations
range (e.g. 100...250 V AC and DC)
- only 4 coils to cover control voltages between 24 ... 250 V 50/60 Hz and 12 ... 250 V DC
- allow direct control by PLC-output ≥ 24 V DC 500 mA
- reduced panel energy consumption
NFZ44E - 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 side mounting and a wide range of accessories.
