The TE Connectivity 1SNK508020R0000 ZS10-BL is a high-capacity blue screw clamp feed-through terminal block designed for reliable power and signal connections in industrial electrical panels, machinery and automation systems. As part of the TE Connectivity ENTRELEC SNK series, it combines secure screw termination with a compact DIN rail format for dependable and organised industrial wiring.
The ZS10-BL is designed for conductors up to 10 mm² / 6 AWG while occupying just 8 mm of DIN rail width. Its blue polyamide housing makes it particularly useful where colour-coded circuit identification is required, while the screw clamp connection provides a robust and familiar termination method for installation and maintenance engineers.
Rated at 57 A and 1000 V IEC, the ZS10-BL is suitable for demanding power and signal applications, including installations requiring high voltage capability. It offers two connection positions, IP20 protection, UL 94V-0 flammability-rated material and a wide -55–110 °C operating temperature range for dependable service in industrial environments.
Feed-through terminal blocks provide a secure and organised method of joining conductors within electrical control panels and machinery. The TE Connectivity ZS10-BL uses screw clamp technology to maintain dependable electrical contact while allowing conductors to be installed, inspected and maintained efficiently.
The ZS10-BL combines a 10 mm² conductor capacity with an 8 mm terminal width, helping engineers achieve high-capacity connections without unnecessarily increasing DIN rail space. Its 1000 V IEC voltage rating also makes it suitable for demanding industrial power distribution and other applications requiring higher operating voltages.
