NF(Z)B 4 and 8-pole contactor relays

AC operated - connection with standard ferrules

Description
NF(Z)B contactor relays comply with the latest railway rolling stock standards and allow installation in
passengers or driver cabins for trains frequently operating tunnels or undergrounds. They are used for
switching auxiliary and control circuits. These contactor relays are of the block type design with 4 or 8 main
poles. 2
– designed in accordance to the applicable parts of IEC 60077 and EN 50155 standard
1SBC101024V0014 – shocks and vibration withstand conforming to IEC 61373 (category 1, class B)
– fire and smoke safety compliance to european standard EN45545 (HL2, HL3 hazard levels)

voltage range Uc min. ... Uc max. of the contactor. Max. permitted control voltage must not be exceeded
NFZB22E – electronic coil interface accepting sinusoidal AC 50/60 Hz control supplies included inside the wide control
during voltage fluctuation defined according to IEC 60077 or EN 50155 (see technical data)
– built-in surge suppression
– side by side mounting without restriction from -40° C up to +70° C
– add-on auxiliary contact blocks for front or side mounting and a wide range of accessories.
