Availability set by the retailer

The WAGO 221-682 Series Lever-Nuts for Hazardous Locations are lever-actuated, tool-free wire splicing connectors engineered for use in demanding and hazardous-area electrical applications. Designed as an all-purpose terminal block of ignition protection type Ex e ("Increased Safety"), these connectors are rated for use in zones 1 and 2, making them ideal for junction boxes, distribution boxes, terminal boxes, lighting, and electronic devices in industrial and hazardous environments. Each 2-conductor connector accommodates solid, stranded, and fine-stranded conductors from 20-10 AWG, with a rated current of 30 A and a rated voltage of 440 V (with spacing between adjacent connectors). The transparent housing with white operating levers lets you visually confirm the connection, while the lever design means there is no twisting and no taping — simply pull the lever up, insert a conductor, and push the lever back down. Recessed side handles provide a secure grip, and a test point on each side allows convenient voltage testing even when installed. The connectors are UL 486C listed for solid or stranded wire and meet rigorous standards for pull-out, temperature-cycling, vibration, and corrosion resistance, with an upper temperature rating of 105 °C. Reusable and re-leverable with no loss of connection integrity, they support DIN-rail mounting via optional mounting carriers (vertical or horizontal). This box contains 50 pieces. Brand: WAGO; Model: 221-682; Connector Type: Spring Clamp; Number of Poles: 2; Mounting Type: DIN Rail; Material: Lead; Color: Orange. As the originator of spring pressure technology, WAGO has been the market leader in reliable connections since 1951, with billions of connections in service worldwide. Ideal for electricians, HVAC technicians, appliance and RV installers, and DIYers working in hazardous-location or industrial electrical wiring.

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.
