The WAGO 281-603/281-400 terminal block is a versatile solution for connecting and distributing power in industrial environments. Designed for use on DIN rails (35 x 15 and 35 x 7.5), it incorporates a diode and utilizes WAGO’s innovative CAGE CLAMP® spring pressure connection technology for robust and reliable connections. For aluminum conductors, the use of WAGO’s “Alu-Plus” contact paste is recommended to ensure optimal performance and prevent corrosion. This terminal block is ideal for applications requiring secure and efficient power distribution, such as control panels, automation systems, and machinery.
