CONTA-CLIP
The ZSL earth terminals (2.5–16 mm²) are rugged, single-level DIN‑rail tension‑spring terminals ideal for grounding connections. Crafted from flame‑retardant PA6.6 (polyamide 6.6), they withstand temperatures from –40 °C to +120 °C and meet UL94 V‑0 standards for flammability. Each terminal supports standard wire sizes and is equipped with multiple approvals (UL, CSA, cUL, GL, KEMA, EAC), making them suitable for global installations. The units offer two test‑pick‑off options and are rated for pollution degree 3 with over‑voltage category III, ensuring reliable performance in industrial control panels and switchgear systems. Their green/yellow coloration adheres to grounding safety standards, providing quick visual identification.
These terminals serve as a secure and space‑efficient solution for grounding both single and stranded copper conductors, effectively maintaining earth continuity in electrical cabinets, machinery, and building automation systems. The tension‑spring connection ensures consistent contact pressure without the need for screws, reducing installation time and ensuring low‑maintenance reliability even under vibration. With compact dimensions (as slim as 5.1 mm) and a variety of connection counts and mounting heights (39–51 mm), the ZSL series facilitates dense terminal block layouts while preserving terminal space integrity. Ideal for protecting personnel and equipment, these terminals are a cornerstone component for glue‑less, high‑efficiency grounding infrastructure.Â
