NF 8-pole Contactor Relays

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
• 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
- very distinct closing and opening
• built-in surge suppression
• add-on auxiliary contact blocks for side mounting and a wide range of accessories.
