WAGO 221-483 Lever-Nuts Ex Splicing Connector (3-Conductor, 24-12 AWG, Box of 50)

Brand: WAGO

Availability set by the retailer

The WAGO 221-483 is a COMPACT splicing connector from WAGO's renowned 221 Series Lever-Nuts, engineered specifically for use in hazardous locations (Ex applications). This 3-conductor variant features tool-free, lever-actuated operation that lets electricians and technicians connect solid, stranded, and fine-stranded conductors ranging from 24 to 12 AWG quickly, reliably, and safely without needing any additional tools. Each connector has a transparent housing that allows visual inspection of the wire connection to confirm proper insertion and contact, plus white operating levers that open and close the clamping unit with minimal effort. The Ex certification means this connector is approved for use in explosion-hazard zones (Zone 1 and Zone 21 for gases and dusts, as well as Zone 2 and Zone 22), making it suitable for distribution boxes, terminal boxes, lighting fixtures, and electronic devices operating in industrial, chemical, oil-and-gas, and other potentially explosive atmospheres where standard connectors are not permitted. WAGO's proven lever technology uses a tension spring clamping system that provides gas-tight, vibration-resistant, and maintenance-free connections, eliminating the risk of loose wires caused by vibration or thermal cycling that plague traditional twist-on wire nuts and screw terminals. The compact form factor saves valuable space in junction boxes and enclosures, and the lever design allows wires to be released and reconnected repeatedly for modifications, testing, or troubleshooting without damaging the conductor. This listing is for a full box of 50 pieces, giving electricians and maintenance teams an economical pack size for larger installations, panel builds, or stock replenishment. Manufactured by WAGO Kontakttechnik GmbH & Co. KG in Germany to exacting quality standards, the 221-483 carries UL listing and meets IECEx and ATEX requirements for Ex applications.

Choosing Electrical

What makes a hand tool safe for electrical work?

Insulated tools rated to a recognized standard such as VDE 1000V protect against shock up to their rated voltage when the insulation is intact. Always verify the circuit is de-energized first — insulated tools are a backup, not a substitute for lockout/tagout and testing with a verified voltage tester.

Which wire tool do I need?

Match the tool to the task: wire strippers remove insulation cleanly at the right gauge, linesman pliers grip and cut, and diagonal cutters trim flush. For repeated connections, a self-adjusting stripper speeds work and reduces nicks. Always match the tool to the wire gauge and insulation type.
