The TE Connectivity ENTRELEC ZS4-RD 1SNK505062R0000 is a compact 4 mm² feed-through screw clamp terminal block designed for reliable conductor connections in control panels, distribution equipment and industrial automation systems. Part of the established ENTRELEC SNK Series, this version features a distinctive red polyamide housing and provides two connection positions on a single level.
The ZS4-RD combines a space-saving 5.2 mm terminal pitch with conductor capacity up to 4 mm². Its screw clamp connection provides a secure and familiar termination method for rigid and flexible conductors, while the DIN rail mounting design enables straightforward installation alongside other SNK Series terminal blocks.
Rated at up to 32 A and 1000 V IEC, the 1SNK505062R0000 is engineered for demanding electrical applications. It offers an operating temperature range of -55 to 110 °C, IP20 protection and a UL 94V-0 flammability rating, providing a robust solution for professional industrial wiring installations.
Feed-through terminal blocks provide a convenient method of joining conductors through a control panel or electrical enclosure while maintaining an organised DIN rail installation. The TE Connectivity ENTRELEC ZS4-RD uses established screw clamp technology to create secure conductor connections while its compact 5.2 mm pitch helps reduce the amount of DIN rail space required.
With support for conductors up to 4 mm², a 32 A IEC current rating and 1000 V IEC voltage rating, the 1SNK505062R0000 is suitable for a broad range of power distribution, control and automation wiring. The red housing also makes the terminal easy to distinguish within mixed-colour terminal assemblies where visual circuit identification is required.
