Cross connection terminal (terminal), plug-in, blue, 24 A, Number of poles: 3, Pitch in mm: 5.10, Insulated: Yes, Width: 13 mm, ZQV 2.5N/3 BL 1527770000

Cross-connection comb for potential distribution in control cabinets

The ZQV 2.5N/3 BL cross-connection enables the rapid connection of three terminals in a single line - without the need for individual jumpers or additional wires. Simply plug the jumper into the appropriate sockets on the terminal block to transfer a signal or distribute potential between adjacent circuit elements.

The blue version of this jumper is particularly useful when constructing installations that require the separation of functional circuits - for example, when creating signal groups, distributing auxiliary voltages, or organizing wiring in industrial automation switchgear.

Design and mounting method

The jumper is designed as a plug-in element, which means lightning-fast installation - just a hand movement is required, without tools and without loosening screws. It is plugged directly into the jumper sockets of A-series terminals, offering a 5,1 mm pitch matched to the standard blocks of this system.

The design ensures finger-safe protection, so the jumper can be mounted even when the cabinet remains live - which is important during service work and installation expansion.

Operating parameters and execution

The rated current of 24 A allows for the transmission of sufficient power for most control and signaling circuits encountered in industrial applications - from simple PLC circuits to more complex automation systems.

The insulated housing protects against accidental short circuits between adjacent connection paths. The jumper features certified Ex-e explosion-proof design, meaning compliance with requirements for explosion-hazardous zones - it can be used in industrial installations covered by the ATEX directive.

The total width is 13 mm, so the three-pole jumper occupies minimal space on the DIN rail.

Advantages for the installer and end user

• Fast tool-free mounting - eliminating the time-consuming tightening of screw jumpers results in fewer operations and fewer potential failure points.
• Configuration flexibility - three paths allow for the construction of basic connection groups; the ZQV series also includes versions from 2 to even 50 poles, making it easy to select a jumper suited to the project scale.
• Durable electrical connection - plug-in contacts maintain contact even under vibrations typical of industrial environments.
• Blue color as a functional marking - facilitates circuit identification during switchgear diagnostics and maintenance.

The ZQV cross-connection comb is effective both for the original switchgear setup and for subsequent expansion - simply add another jumper or change its configuration without interfering with existing screw connections.
