221-423 3-Port Lever Connector | Universal Terminal Block (0.2-4mm²) | Transparent

The 221-423 is a three-port lever connector for joining conductors from 0.2mm² to 4mm², with no tools needed on site.

What the specs mean for you

• 450V / 32A rating — covers all conductor types across the 0.2-4mm² range, so one connector handles thin signal cores and heavier supply cables alike.
• 11mm strip length — set your strippers to this before you start; get it wrong and the lever won't seat the conductor properly.
• 85°C operating temperature — relevant if the connector sits near a heat source, such as inside a densely packed enclosure.
• Transparent PC/PBT housing — lets you see that each conductor is fully inserted before you close the lever, useful for a quick visual check during snagging or inspection.

Build and lever action

The lever opens and closes by hand — no crimping tool or screwdriver required. The housing is made from 77% bio-circular PC, with the levers themselves 27% recycled PBT, so there's a sustainability angle alongside the practical one.

Where it fits

For CCTV installers, this type of connector is generally used for joining power or signal cores within an enclosure or junction box rather than in the camera housing itself — check your specific run against the 0.2-4mm² range before choosing it.
