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.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
