Cross-connection terminal, plug-in, orange, 24 A, Number of poles: 2, Pitch in mm: 5.10, Insulated: Yes, Width: 7.9 mm, ZQV 2.5N/2 1527540000

Fast connections in control cabinets and switchgear

The ZQV 2.5N/2 plug-in jumper is used for potential distribution between adjacent terminal blocks - it enables the transfer of a signal or power without the need for additional wiring. Simply plug the element into the terminal slots to connect any number of contacts in one continuous circuit. Plug-in technology eliminates the need for tools and shortens installation time compared to screw-type solutions - this is particularly important in large projects where every minute on the construction site counts.

The product is made of Wemid plastic, which is characterized by high thermal resistance - the element operates in the range of −60 °C to +130 °C, allowing for use in both cold warehouse halls and near heating components. The UL 94 V-0 flammability class means that the material self-extinguishes and does not support combustion - which is vital in industrial applications with strict fire safety requirements.

Electrical and mechanical parameters

The plug-in jumper carries a rated current of 24 A at a rated voltage of 400 V. Two poles with a 5,1 mm pitch match the standard pitch of popular terminal blocks, ensuring precise geometric fit. The total width of the element is 7,9 mm, height 24,7 mm, and thickness 2,8 mm - compact dimensions allow for mounting even in densely packed control cabinets.

Important limitation: for stability and thermal reasons, a maximum of 60% of the contacts can be broken out. When cutting the plug-in jumper with raw edges, the operating voltage drops to 25 V - this must be kept in mind when designing circuits.

Compatibility and operating conditions

The element is designed to work with Weidmuller Klippon Z series feed-through terminals. Mounting is performed by sliding it into the mounting slots - without additional clamping elements. The explosion-tested (ATEX) version extends the range of applications to explosion-hazardous zones.

Storage temperature: −25 °C to +55 °C. The product is insulated, which protects against accidental short circuits between contacts.

Standards and compliance

The plug-in jumper complies with the requirements of the RoHS directive (without SVHC substances above 0.1% by weight) and has an ETIM classification as an accessory for terminal blocks. Wemid material ensures mechanical and chemical durability - the manufacturer guarantees connection reliability even with partially broken contacts.
