NF 8-pole contactor relays

AC / DC operated

Description
NF 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 NF33/11 and NF51/11 variants
– overlapping of lagging / leading contacts for NF33/11 and NF51/11 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...500 V 50/60 Hz and 20...500 V DC
- reduced panel energy consumption
NF44E
- very distinct closing and opening
– built-in surge suppression
– add-on auxiliary contact blocks for side mounting and a wide range of accessories.
