The TE Connectivity ZS4-OR 1SNK505030R0000 is a compact and dependable orange screw-clamp feed-through terminal block designed for secure conductor connections in industrial control panels, switchgear and automation equipment. Part of the TE Connectivity ENTRELEC SNK ZS series, it combines proven screw-clamp technology with a space-efficient DIN-rail format for professional electrical installations.
The ZS4-OR is a single-level feed-through terminal with two connection positions, providing a straightforward method of joining incoming and outgoing conductors. Its orange polyamide housing enables clear visual identification and colour coding within terminal assemblies, helping simplify installation, commissioning, troubleshooting and maintenance.
Designed for conductors up to 4 mm², the ZS4-OR provides an IEC rated current of 32 A and supports applications rated up to 1000 V AC/DC IEC. Its narrow 5.2 mm spacing allows high-density terminal arrangements while compatibility with standard TH35 DIN rails simplifies integration into industrial electrical cabinets.
Feed-through terminal blocks provide an organised and serviceable method of connecting conductors inside electrical cabinets. The TE Connectivity ZS4-OR uses a conventional screw-clamp mechanism to establish a secure conductor connection while allowing straightforward installation, inspection and maintenance using standard panel-building tools.
The compact SNK-series design accommodates conductors up to 4 mm² within just 5.2 mm of DIN-rail width. Combined with the orange housing and extensive SNK accessory system, this makes the ZS4-OR well suited to structured, colour-coded terminal assemblies in modern industrial equipment.
