Mounting fitting ZJUN-2x35/ red=12PCS R34RR-07010020303

Al/Cu busbar connector ZJUN-2x35 designed for connecting aluminum and copper conductors with a rated cross-section of 35 mm² in installations with a voltage up to 1000 V. Used in LV switchboards and distribution systems requiring a safe and durable connection of Al and Cu cores.

The connectors meet the requirements of the PN-EN 60947-7-1 standard regarding terminal blocks for copper conductors. Additionally, they have passed the short-circuit test in accordance with IEC TS 60947-7-5:2021 (clause 9.4.6) for connectors working with aluminum cores.

The current path made of tin-plated aluminum alloy ensures compatibility with Al and Cu conductors and limits the risk of contact corrosion. Steel screws coated with contact paste improve contact quality and connection stability. The polyamide 6.6 body and cover provide high mechanical strength and UL 94 V0 flammability rating.

The connector is intended exclusively for mounting on a TSE 35 rail and, thanks to its compact design, can be installed under the modular device trim.
