The 221 inline splicing connector allows universal conductor connection and a visibly secure conductor contact. It comes with intuitive orange levers for tool-free wiring for solid, stranded and fine-stranded conductors from 12-20 AWG. Equipped with spring-pressure, maintenance-free Cage Clamp connection technology, the connectors offer the option of using additional adapters where multiple poles are required. Whether with or without strain relief, a modular and flexible connection is possible with a snap-in mounting foot, screw, adhesive, tie-on or suspended mounting and can be placed on a 15- or 35-mm DIN rail.
