NF(Z)B..K contactor relays - with Push-in Spring terminals
AC operated

NF(Z)B..K contactor relays comply with the latest railway rolling stock standards and allow instal-
lation 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 control voltage must not be exceeded during voltage fluctuation defined according to IEC 60077 03
• electronic coil interface accepting sinusoidal AC 50/60 Hz control supplies. Maximum permitted
or EN 50155 (see technical data)
NF(Z)B22EK • 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.
