NFZ 8-pole contactor relays

AC / DC operated

Description
NFZ contactor relays are used for switching auxiliary and control circuits.
These contactor relays are of the block type design with:
– 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
1SBC101029V0014 – 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 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
NFZ44E
- 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 side mounting and a wide range of accessories. 5
