The WAGO 281-664 is a robust and reliable 4-conductor through terminal block ideal for a variety of industrial applications. Designed for DIN-rail 35 x 15 and 35 x 7.5 mounting, this terminal block utilizes WAGO’s innovative CAGE CLAMP® spring pressure connection technology, ensuring secure and vibration-resistant connections. It is particularly well-suited for solid aluminum conductors when used in conjunction with WAGO’s “Alu-Plus” Contact Paste, which prevents oxidation and corrosion. The terminal block’s center marking simplifies identification and organization within electrical panels. With a rated voltage of 800V and a rated current of 26A, the 281-664 provides a safe and efficient solution for power distribution and signal transmission in industrial environments.
