        Wago | 2-Way Compact Splicing Connector 4mm² 32A | Transparent

        The Wago 221-412 is a 2-way splicing connector rated for solid, stranded, and fine-stranded conductors from 0.14 to 4mm², with a rated current of 32A and nominal voltage of 450V. The 221-412 uses Wago's CAGE CLAMP® technology with a lever-operated actuation system, requiring no tools to create secure electrical connections. Supplied in a jar of 100 connectors with transparent polycarbonate housing and orange actuators, this product is designed for fast, secure conductor splicing in tight spaces.

        Electricians frequently face connection challenges in junction boxes and ceiling canopies where space is limited and traditional screw connectors are either cumbersome or time-consuming. Splicing connectors bridge this gap: they compress installation cycles, reduce hand fatigue, and eliminate fumbling with screwdrivers in confined spaces. The 221-412 is ideal for retrofit wiring, pendant light installations, and long cable runs where simplicity and speed matter as much as connection integrity.

        The Wago 221-412 delivers value through tool-free operation — just pull the lever, insert the conductor, and push down to clamp — and compact form factor that fits standard junction boxes without forcing a choice between space and security. Electricians choose the 221 Series because the transparent housing allows visual confirmation of conductor seating, and the lever's resting position prevents accidental unclamping during installation or vibration. The 32A rating and 450V nominal voltage handle the vast majority of residential and light commercial circuits without compromise, reducing SKU proliferation on the job site.

        Features

        • Lever-operated actuation — pull the lever up, insert the stripped conductor, and push down to clamp; no tools, no screwdriver fumbling, and no cross-threading risk.
        • Accepts solid, stranded, and fine-stranded conductors — handles 0.14 to 4mm² conductor cross-sections, accommodating building wire, stranded control wiring, and fine-stranded LED leads on the same connector.
        • 32A rated current — suitable for general-purpose lighting and power subcircuits, handling multiple downlights, pendants, and low-load branches without derating.
        • Compact dimensions — 13.2mm width, 8.6mm height, and 18.8mm depth fit standard single-gang junction boxes, leaving clearance for bulk cable runs and reducing the need for surface-mounted alternatives.
        • CAGE CLAMP® technology — spring-clamp design holds conductors firmly without damage, eliminating conductor strand loss and maintaining connection integrity over time even with vibration exposure.
        • Transparent polycarbonate housing — allows visual inspection of conductor seating before closure, reducing the risk of missed or half-inserted wires on complex splices.
        • Lever rest position — the orange actuator locks in the down position, preventing accidental lever lift during installation and protecting the connection from unintended opening due to vibration or handling.
        • 450V nominal voltage rating — complies with IEC/EN 60664 Overvoltage Category II and Pollution Degree 2, suitable for standard domestic and light commercial branch circuits.
        • 4 kV rated surge voltage — provides protection headroom for transient voltage events common in residential installations, meeting EN 60998 compliance.
        • 11mm strip length — the conductor must be stripped to 11mm; this standardised dimension simplifies preparation and reduces wire loss compared to screw connectors requiring longer strip lengths.
        • Jar of 100 connectors — bulk packaging reduces cost per unit and supports medium-scale projects such as new-build wiring or staged renovations without frequent restocking.
        • Interior use only — the 221-412 is not weatherproof or rated for external exposure; it is suitable for dry indoor locations such as junction boxes, ceiling voids, and building cavities only.

        Where to use

        • Pendant light and ceiling canopy installations — the Wago 221-412 is ideal for fine-stranded pendant cords connecting to building wire in suspended ceilings, junction boxes, and light fittings where space is constrained and speed matters.
        • Downlight wiring runs — retrofit downlight circuits frequently use 4mm² building wire to the first fitting, then transition to smaller stranded runs for individual downlights; the 221-412 handles both on the same connector.
        • Long cable runs with larger conductor cross-sections — the 4mm² rating supports the full capacity of building wire commonly used in domestic extensions, new-build wiring, and multi-outlet circuits.
        • Junction box splicing — the compact form factor and transparent housing make the 221-412 the standard choice for splicing circuits inside standard Australian junction boxes without external bulk or obstruction.
        • LED lighting and low-voltage control systems — the ability to accept 0.14mm² fine-stranded wire opens the door to 12V LED systems, control circuits, and sensor wiring without requiring separate ultra-fine connectors.
        • Renovation and retrofit wiring — when existing circuits must be extended or branches added, the 221-412 speed and simplicity reduce labour time compared to screw terminals, making retrofit economics more favourable.

        The Wago 221-412 is not suitable for external walls, weatherproof enclosures, or damp exposed locations. The transparent polycarbonate housing is designed for interior dry environments only. Do not use the 221-412 outdoors, in bathrooms, kitchens with splash zones, laundries, or any location subject to moisture or temperature extremes above 85°C.

        Verified Sparky Direct customer reviews: Wago 221-412 2-Way Compact Splicing Connector (221-412)

        "Excellent product for wiring. Never an issue." — Alright electrics

        "Easy to use & simple. Less time consuming, great connection." — Major lienert

        "Really quick and easy, I will be buying more." — Pommilength

        (221-412)

        The 221-412 accepts solid conductors from 0.2 to 4mm², stranded conductors from 0.2 to 4mm², and fine-stranded conductors from 0.14 to 4mm² (24 to 12 AWG). The connector works with copper conductors only.

        Strip the conductor to 11mm. Lift the orange lever to open the clamping unit, insert the stripped conductor, and push the lever back down flush with the housing. The connection is complete; no tools are required.

        Yes. Wago offers 2-way, 3-way, and 5-way variants in the 221 Series. The 221-412 is the 2-way version for 4mm² conductors. For 6mm² conductors, the 221-612 is available. For 3-way splitting, the 221-413 is a common choice.

        The 221-412 is rated for 32A continuous current at 450V nominal voltage. It complies with EN 60998 Overvoltage Category II and Pollution Degree 2, making it suitable for standard domestic branch circuits without deration.

        Yes. The compact dimensions (13.2mm wide, 8.6mm high, 18.8mm deep) make the 221-412 ideal for standard Australian junction boxes and ceiling voids where space is limited. The compact form fits comfortably without forcing a choice between space and secure connection strength.

        The 221-412 is designed for interior installation inside junction boxes and ceiling voids, not for direct sunlight exposure. If the connector is installed in a location with direct or prolonged indirect sunlight (such as a ceiling-mounted junction box in a conservatory), cover it with an opaque blanket or keep it enclosed in the junction box to protect the polycarbonate from UV degradation.

        The Wago 221-412 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
