Cross-connection terminal (terminal), plug-in, orange, 24 A, Number of poles: 3, Pitch in mm: 5.10, Insulated: Yes, Width: 13 mm, ZQV 2.5N/3 1527570000

Distribution of potentials and signals in electrical switchgear

The ZQV 2.5N/3 cross-connection terminal is a compact component designed for bridging terminal blocks - it enables signal routing or potential distribution through several terminals simultaneously without the need for individual wiring of each one. In practice, this means fewer wires in the control cabinet, faster installation and a clearer connection layout.

The product belongs to the Weidmüller ZQV series - one of the most recognizable manufacturers of connectors and terminal blocks in the industrial market. Potential distribution is a fundamental operation in the construction of industrial switchgear, and cross-connectors of this type are standard equipment for every installer working with this manufacturer's terminals.

Design and electrical parameters

The connector is a plug-in type - it is mounted directly onto appropriate terminal blocks from the Z series (hence the ZQV designation). The plug-in design means a simple, screwless installation method: the component is inserted into the slots on the terminals and that's it. No tools or additional mounting accessories required.

Three poles allow simultaneous connection of three adjacent points in the circuit. The rated current of 24 A and pitch of 5.10 mm determine compatibility - the connector is dedicated to feed-through terminals with a wire cross-section up to 2.5 mm², which covers the most popular range used in industrial automation.

The width of the entire component is 13 mm, and the height and depth fit in a compact format (dimensions similar to a single terminal module). This means it does not disrupt the cabinet geometry even with dense packing of components.

Insulation and safety

The connector is fully insulated - the housing made of material rated UL 94 flammability class provides protection against accidental contact with live parts (touch protection). This is important both during daily operation of the switchgear and in the context of occupational safety requirements.

German production confirms high manufacturing quality. Additionally, the component has confirmed explosion-proof Ex-e design, which opens the possibility of using it in explosion-hazard zones - where normally installation requires special certifications.

It meets the requirements of the RoHS directive and REACH regulations - it does not contain substances subject to restrictions.

Compatibility and ecosystem

ZQV 2.5N/3 fits a wide range of Weidmüller Z series terminal blocks (both PUSH IN A-Series and screw-type W-Series). The manufacturer offers these connectors in various pole configurations - from 2-pole up to 50-pole - and in several colors (orange, red, blue), which allows for logical separation of circuits already at the color-coding stage.

The ZQV series is part of a larger ecosystem of Weidmüller terminal accessories including end plates, mounting brackets (WEW/ZEW/AEB) and labeling - all designed to fit together without the need for dimension matching.
