WERA 781 A/B 1/4 liitososa 05042670001

The WERA 781 A/B 1/4 Connection Part is a versatile electrical connector module engineered for reliable wire termination using CAGE CLAMP® technology. It provides eight connection points (four per side) for solid, stranded, and fine-stranded conductors up to 1.5 mm², making it ideal for industrial and building automation applications.

Advantages

The CAGE CLAMP® spring pressure connection ensures maintenance-free, vibration-resistant terminations without the need for special tools. The module features a compact snap-on design for quick mounting on carrier rails or adapters, and its polyamide (PA 66) housing offers excellent mechanical and thermal stability.
