279-621 Description

Short technical summary and product information.

The Wago 279-621 is a 4-conductor through terminal block from the 279 series, designed for DIN-rail mounting on 35 x 15 mm or 35 x 7.5 mm rails. It features CAGE CLAMP spring clamp termination for fast, maintenance-free wiring of solid and fine-stranded copper conductors from 0.08 to 1.5 mm² (28-16 AWG).

 

Electrical ratings per IEC/EN 60947-7-1 are 18 A rated current and 800 V nominal voltage, with an 8 kV rated impulse withstand voltage. UL 1059 and CSA 22.2 No 158 approvals provide 600 V / 10 A ratings for Use Group C. The block has a power loss of 0.5929 W per pole at rated current.

 

With a width of 4 mm, height of 68 mm, and depth of 27 mm from the DIN rail, this compact feed-through terminal block is suitable for industrial and building wiring applications. Front-entry wiring and side marking simplify installation and identification.
