NFZB 4 and 8-pole contactor relays

DC operated - connection with standard ferrules

Description
NFZB 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
2 poles.
– 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 EN 45545 (HL2, HL3 hazard levels)
– electronic coil interface accepting a wide DC control voltage range (0.85 Uc min. ... 1.1 Uc max. according
to IEC 60947-4-1) including several Uc control voltages (0.7 ... 1.25 Uc according to IEC 60077) used for
NFZB22E
battery supply
– low coil consumption
– 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.
