Feed-through terminals

ZRKS and ZSLS models feature 2, 3, or 4 connections, with 1, 2, or 4 of those connections designed to receive the ZST plug. Based on a modular design, the system allows users to pre-wire machines and control cabinets. The safe-to-touch components can be plugged in and disconnected without any tools, thereby facilitating the connection or exchange of prefabricated functional units. The connection system consists of ZST plugs, ZSTK couplings, and the new ZRKS feed-through terminals and ZSLS PE terminals

The stainless steel tension springs and the corrosion-free alloy of the contact material ensure safe contacting that resists even extreme vibrations. The connection system is designed for a rated current of 24A, a rated voltage of 500V, and a wire cross-section of up to 4mm².

ZSTK couplings are available for installation on TS 15 or TS 35 DIN rails, or as flying leads. The terminals enable vibration-proof installation without any screws by simply snapping them onto the mounting rail. Made from polyamide PA6.6, the housings withstand temperatures between -40 and 120°C. They offer a creepage resistance of CTI 600 and are categorised as flammability class V0 according to UL. CONTA-CLIP provides a wide range of accessories for the connection system.
