Mounting connector ZJUN-5x35 GREY=8PCS R34RR-07020004303

Al/Cu rail terminal block ZJUN-5x35 designed for connecting aluminum and copper conductors with a nominal cross-section of 35 mm² in installations with voltage up to 1000 V. Used in low-voltage switchgear and distribution systems requiring safe and durable connection of Al and Cu conductors.

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

The construction includes 5 current paths separated by insulating barriers, which increases operational safety and installation clarity. The current path made of tinned aluminum alloy ensures compatibility with Al and Cu conductors and reduces the risk of contact corrosion. Steel screws coated with contact paste improve contact quality and connection stability.

The body and cover made of polyamide 6.6 provide high mechanical strength and UL 94 V0 flammability class. The terminal block can be mounted on a 35 mm DIN rail or directly to the surface, also under modular equipment covers.
