Cross connection terminal (jumper), plug-in, red, 17.5 A, Number of poles: 2, Pitch in mm: 3.50, Insulated: Yes, Width: 5.5 mm, ZQV 1.5N/2 RD 1985650000

Effective potential distribution in switchgear

The ZQV 1.5N/2 RD cross-connector is a compact cross-connector designed for plug-in mounting in terminal blocks. Its primary function is to create electrical connections between adjacent terminals - enabling potential distribution or signal transmission without the need for additional wiring.

The two-pole design allows for the simultaneous connection of two adjacent terminals in a single mounting step. The 3,5 mm pitch ensures precise fit to standard terminal strips with a cross-section of 1,5 mm², corresponding to the most popular sizes used in industrial automation and control installations.

The red color coding facilitates the identification of voltage paths (L) in the switchgear - particularly useful during service work and diagnostics.

Construction and compatibility

The housing is fully insulated, eliminating the risk of accidental contact with conductive elements during installation and operation. The built-in touch protection meets safety requirements in standard switchgear applications.

The connector is dedicated to the ZQV series - Weidmüller cross-connectors compatible with the Klippon Connect range of terminals (both PUSH IN A-Series and screw W-Series). Installation consists of plugging the connector from above into specially profiled sockets of the terminal strip - without the use of tools, which significantly accelerates cabling work.

The total width of 5,5 mm corresponds to two poles at a 3,5 mm pitch - the design maintains proportions typical for standard terminal blocks.

Operating parameters and safety

The rated continuous current of 17,5 A allows for the transmission of sufficient power for most low-voltage control circuits - from powering sensors and transducers to signaling circuits and the distribution of 24 V DC auxiliary voltages.

The rated operating voltage reaches 400 V AC/DC, covering typical network applications (230/400 V) and installations with stepped-down voltages used in automation.

This version features Ex e (explosion-proof) certification, meaning it is suitable for use in explosion-hazardous areas - where standard components could pose an ignition source.

Practical applications

In installation practice, the ZQV 1.5N/2 RD excels in:

• constructing busbars supplying groups of output modules,
• creating common grounds (GND) for multiple measurement circuits,
• distributing control signals between several receiving devices,
• creating potential bridges between terminal strip sections without additional wiring.

The red color scheme facilitates wiring organization - separating power, signal, or ground paths reduces the risk of errors during installation expansion or modification.
