Weidmuller ZDU Series DIN Rail Terminal Blocks

Weidmuller ZDU Series DIN Rail Terminal Blocks feature a universal contact system with spring connection and tension clamp technology. The terminal blocks offer a highly reliable top-entry conductor feed to ensure absolute clarity and easy handling, which is ideal in compact panel construction. The ZDU series has a modular design and pluggable standard cross-connections for flexible potential distribution. The ZDUA and ZDUB series deliver a practical design in standard- or roof-style variants with a standard 0.13mm2 to 4mm2 max clamping range. The Weidmuller ZDU Series DIN Rail Terminal Blocks are shock- and vibration-proof with electrical and mechanical function separation, ideal for various automotive and railway applications.
