The UKK3 is a durable three-level DIN rail terminal block designed for high-density power wiring management in control panels, switchboards, and enclosures. Supporting up to 300V and 25A, this terminal block is optimized for 0.2–2.5mm² conductors (18–12 AWG), making it ideal for industrial and building cabling applications. With a compact and rectangular shape built from flame-retardant PA66 nylon, the UKK3 features a screw-clamp feed-through system that ensures safe, strong, and long-lasting connections. Internally, it uses pure copper contacts for maximum conductivity and corrosion resistance. Whether you're wiring lighting, control, or power lines, this three-level terminal block offers efficient, organized, and space-saving electrical distribution.
The UKK3 three-level DIN rail terminal block is purpose-engineered to meet modern power distribution needs in space-constrained panels and industrial control systems. Featuring a three-tiered structure, this terminal block allows for the routing of three independent circuits in a single unit – perfect for maximizing DIN rail space while organizing wiring paths efficiently. Constructed from UL94 V-0 flame-retardant PA66 nylon, the UKK3 provides mechanical strength, excellent insulation properties, and resistance to high-temperature environments. It accommodates conductor sizes from 0.2 to 2.5mm² (equivalent to 18–12 AWG), making it versatile for both building cabling and industrial control systems. Each level uses a screw-type feed-through connection, ensuring a secure electrical contact between cables even in vibration-intensive environments such as motor control panels or machine enclosures. Pure copper conductors enhance current-carrying efficiency and safeguard against long-term oxidation, ensuring optimal connectivity and reliability. Rated at 300V and 25A, the UKK3 terminal block is compatible with various AC/DC electrical setups commonly found in power supply racks, PLC systems, and LED control modules. Measuring 61 × 57 × 52.2mm, the block is both compact and easy to integrate into existing configurations. Like other UK Series terminal blocks, it can be mounted quickly on any standard DIN rail system, ensuring modularity and reconfiguration with minimal downtime. If you need professional-grade cable management in residential, commercial, or automation environments, the UKK3 is a compact, cost-effective, and high-performance terminal solution built for safety and efficiency.
