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

AC operated - connection with ring tongue ferrules

Description
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
– 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 3
NF(Z)B22ERT 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 (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.
