NFZB..RT 4 and 8-pole contactor relays

DC operated - connection with ring tongue ferrules

NFZB..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 EN 50155 standard
1SBC101403F0014 • fire and smoke safety compliance to european standards EN 45545 (HL2, HL3 hazard levels)
• shocks and vibration withstand conforming to IEC 61373 (category 1, class B)
• electronic coil interface accepting a wide DC control voltage range (0.85 Uc min. ... 1.1 Uc max.
