Weidmuller MCZ SERIES Relays and Solid-State Relays



A special feature of the MCZ SERIES is its low profile shape. With a width of only 6 mm, it is particularly well suited for decentralized usage in sub-distribution boards and terminal boxes. You can reduce the installation time by 50 % compared to conventional methods when you use the tension clamp connection and the ZQV 4N pluggable cross-connection on three voltage potential points.

The MCZ TRAK components, which have been developed for the rail industry to comply with the requirements of EN 50155 and EN 61373, are a special highlight. All components have been specially designed to function reliably in temperatures ranging from -40 to +70 °C (and +85 °C for ten minutes). The MCZ TRAK components feature a painted switching element that protects it from condensation which occurs from temperature fluctuations.

The component input circuitry is designed to tolerate on-board voltage fluctuation of -30 to +25 % and ±40 % for 0.1 s (typical for rail applications) without malfunctioning.The MCZ TRAK components also withstand voltage interruptions of over 10 ms without triggering an outage (in compliance with Class S2). In addition, the vibration requirements according to EN 61373/requirements category 1/class B are fulfilled without malfunction or contact interruption. With all of these properties combined, the MCZ TRAK components are a very sturdy and reliable solution for decentralized applications. And not only in the rail industry – they should be used in other industries where conditions are too extreme for conventional components.
