SNA clamp and feed-through terminals are essential components for industrial electrical installations, designed to provide secure and reliable connections for conductors. These terminals, often referred to as through-type terminals or simply feed-through blocks, are available in various sizes and ratings, typically supporting conductor cross-sections from 0.5 mm² up to 240 mm² or more. They feature a robust clamping mechanism, often using a screw or spring-loaded design, ensuring a gas-tight connection that withstands vibration and thermal cycling. Rated voltages commonly range from 400V to 1000V AC/DC, with current ratings from 10A to 400A depending on the model. The insulation material is typically polyamide (PA) or polypropylene (PP), offering high dielectric strength and flame retardancy (UL 94 V-0). These terminals are designed for DIN rail mounting (EN 60715) and can be used in control cabinets, distribution boards, and automation panels.
These terminals are widely deployed in industrial control systems, power distribution networks, and building automation. They are ideal for connecting incoming and outgoing cables in junction boxes, terminal blocks in PLC cabinets, and for wiring sensors and actuators in manufacturing lines. Common sectors include automotive, chemical, food and beverage, and renewable energy installations, where reliable electrical connections are critical for safety and uptime.
The main subcategories within this range include standard feed-through terminals (e.g., SNA 2.5, SNA 4, SNA 6, SNA 10, SNA 16, SNA 35, SNA 70, SNA 95, SNA 120, SNA 150, SNA 185, SNA 240), ground terminals (SNA-PE), and disconnect terminals (SNA-T). The article code typically follows the pattern "SNA" followed by the nominal cross-section in mm² (e.g., SNA 2.5 for 2.5 mm², SNA 16 for 16 mm²). For larger sizes, the code may include additional identifiers like "SNA 95" or "SNA 120".
