TE Connectivity ZS70-PE 1SNK522150R0000 is a green and yellow 70 mm² screw-clamp protective-earth DIN-rail terminal block with 22 mm spacing, screw rail connection, flexible conductor capacity up to 70 mm², rigid stranded capacity up to 95 mm² and an 8400 A short-time withstand rating at 1 second.
Why Choose the TE Connectivity ZS70-PE 1SNK522150R0000 Earth Terminal Block?
The TE Connectivity ZS70-PE 1SNK522150R0000 is a heavy-duty 70 mm² green and yellow screw-clamp earth terminal block designed for dependable protective-earth connections in industrial control panels, switchgear, machinery and power distribution equipment. Part of the TE Connectivity ENTRELEC SNK series, it combines large conductor capacity with a robust screw connection to the DIN rail for reliable electrical and mechanical earthing.
Designed specifically for protective-earth applications, the ZS70-PE provides one circuit, one level and two conductor positions. Its screw rail connection establishes a secure conductive path between the connected protective conductor and the DIN rail, supporting effective grounding in high-current industrial electrical assemblies.
The ZS70-PE has a rated wire size of 70 mm² / 2/0 AWG, accepting flexible conductors from 16–70 mm² and rigid stranded conductors from 16–95 mm². With a 22 mm terminal spacing and a short-time withstand current rating of 8400 A for 1 s, it provides substantial protective-earth capability for demanding installations.
