NFZB Series Information
. NFZB 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.
- Improve the compactness of the installations thanks to reduced dimension and side‑by‑side mounting requiring less 15% width (without spacing) from ‑40 °C up to +70 °C.
- Meet all main rollling stocks standards: IEC 60947‑4‑1, IEC 60947‑5‑1, IEC 60077‑1/‑2 and applicable parts of EN 50155 standards, shocks and vibration withstand conforming to IEC 61373 cat. 1, class B.
- Reach the highest levels in fire and smoke behaviour with compliance to European standard EN 45545‑2 (HL2, HL3 hazard levels) in group mounting.
- Reduce train energy with lighter devices and requiring 68% less coil energy consumption in operation.
- Electronic coil interface handling large DC voltage fluctuation voltage, including several Uc DC control voltages used for battery supply and accepting sinusoïdal AC 50/60 Hz control supplies included inside Ucmin.... Ucmax voltage range.
- Max permitted AC 50/60 Hz control voltage must not be exceeded (see technical data).
- Wide range of auxiliary contact blocks for front and side mounting.
