The WAGO 281-654 is a robust and reliable 4-conductor through terminal block designed for use in a variety of industrial applications. Its CAGE CLAMP® spring pressure connection technology ensures secure and easy connections, while its suitability for Ex i applications makes it ideal for hazardous environments. The terminal block is designed for DIN-rail 35 x 15 and 35 x 7.5 mounting and features a center marking for easy identification. When terminating aluminum conductors, the use of WAGO “Alu-Plus” Contact Paste is recommended to prevent oxidation and corrosion, and nominal currents must be adapted accordingly.
