NFZB..K contactor relays - with Push-in Spring terminals
DC operated

NFZB..K contactor relays comply with the latest railway rolling stock standards and allow installa-
tion 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:
• designed in accordance to the applicable parts of IEC 60077 and EN 50155 standard
• shocks and vibration withstand conforming to IEC 61373 (category 1, class B)
• fire and smoke safety compliance to european standard EN 45545 (H2, HL3 hazard levels)
1SBC101568V0014 according to IEC 60947-4-1) including several Uc control voltages (0.7 Uc... 1.25 Uc according to
• electronic coil interface accepting a wide DC control voltage range (0.85 Uc min. ... 1.1 Uc max.

IEC 60077) used for battery supply
NFZ22EK • 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.
