Eaton ZSD-K Cable Termination Enclosure with Copper Busbars, 250 A, 5-Pole, IP20 232287

In industrial control panels and distribution boards, electricians need a reliable point to split a large incoming cable into multiple smaller branch circuits. The Eaton ZSD-K cable termination enclosure provides a compact, DIN-rail mountable solution with integrated copper busbars for five-pole distribution up to 250 A.

• Branch conductor cross-section: 1.5–50 mm² rigid, 1.5–35 mm² flexible
• Connection type: screw terminals
• Housing material: self-extinguishing thermoplastic
• Protection rating: IP20
• Mounting: DIN rail or screw mounting
• Operating temperature: -25 °C to +70 °C
• Standards: IEC/EN 60947-7-1

Why choose it

The ZSD-K simplifies cable branching by providing a clear, labelled layout for main and branch conductors. Its copper busbars ensure low-resistance connections, reducing heat build-up and improving long-term reliability. The self-extinguishing housing adds a level of safety in the event of an electrical fault.

Ideal use cases

• Distribution of power from a main feeder to multiple sub-circuits in control cabinets
• Connection of large incoming cables to smaller outgoing wires in industrial installations
• Use in building automation and machinery where space is limited and DIN rail mounting is preferred

Good to know

The enclosure is designed for use in dry indoor environments. Always ensure that the total load does not exceed the rated current and that conductors are properly torqued according to the terminal specifications.
