WAGO 221-423 Splicing Connector with Levers 3-Conductor 4mm² 32A

The WAGO 221-423 is a 3-conductor splicing connector with levers from the 221 Series, designed to join solid, stranded, and fine-stranded copper conductors without tools or ferrule preparation. Rated at 32 A and 450 V (EN 60664), it suits high-load applications from intercom system wiring to electric oven connections. The transparent housing allows immediate visual inspection of conductor contact.
