DETAILED DESCRIPTION

A truly standard-setting solution for all conductor types from 0.2 to 4 mm², the new 221 Series Inline Splicing Connector with lever combines all the trusted advantages of the 221 Series Splicing Connectors into a slim design. Offering unsurpassed simplicity, speed and reliability, the 221 Series provides universal conductor connections – with lever technology that eliminates tools – while offering a visibly secure conductor contact. Where multiple poles are required, optional adapters provide completely modular mounting. Users get the flexibility of having five fixed-position poles in one adapter – whether it’s with or without strain relief, on DIN-rails with a snap-in mounting foot, for screw mounting, adhesive mounting, tie-on mounting or suspended mounting. As a universal connection technology, the 221 Series Inline Splicing Connector’s compact dimensions not only improve your current installations, the small footprint also opens up a wide variety of new applications. These include space-restricted applications like laboratory and test setups, production test bays, lighting connection in suspended ceilings, or extending loudspeaker cables and distribution boxes in industrial applications. Two variants of the inline splicing connector are available, both with EN and UL approvals: one version has a transparent cover for conductor cross sections from 0.2 to 4 mm² for all standard applications. The other version uses a white cover (favored in North America) for the extended connection range with AWG-12 conductors.

The differences between the two codes:

Part number 221-2401 features a white top cover, while part number 221-2411 has a transparent top cover. Their technical specifications are identical, with one exception regarding fine-stranded conductors:

Both 221-2401 and 221-2411 accommodate solid conductors with a cross-section of 0.2–4 mm² and stranded conductors of 0.2–2.5 mm²; however, they differ in their compatibility with fine-stranded conductors. Part number 221-2401 accepts 0.34–4 mm², whereas part number 221-2411 accepts 0.2–4 mm².
