Mounting connector ZJUN-3x150 yellow-green R34RR-07020002601

Al/Cu rail connector ZJUN-3x150 designed for connecting aluminum and copper conductors with a rated cross-section of 150 mm² in installations with voltages up to 1000 V. Used in LV switchboards and distribution systems requiring a secure 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 used 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 or directly to a surface.
