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

AC operated - connection with ring tongue ferrules

NF(Z)B..RT 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.
• designed in accordance to the applicable parts of IEC 60077 and EN 50155 standard
1SBC101403F0014 • 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)
• electronic coil interface accepting sinusoidal AC 50/60 Hz control supplies included inside the
wide control voltage range Uc min. ... Uc max. of the contactor. Max. permitted control voltage
must not be exceeded during voltage fluctuation defined according to IEC 60077 or EN 50155
