WAGO 221 series LEVER-NUTS ® Compact splicing connector

High contrast label: The transparent shell is printed with black technical parameter labels (such as voltage, current, wire specifications), which are clear and easy to read, making it convenient for installation personnel to quickly confirm whether the product is suitable for the current scene and avoid model misuse.

Shell protection performance: The shell is made of high-strength engineering plastic, which has a certain degree of dust and light collision resistance, and is suitable for indoor and outdoor general electrical environments (non waterproof design, not suitable for humid or underwater scenes).

2. Key technical parameters (based on international standards)

Technical indicators UL standard (North American market) ENEC standard (European and global markets) Remarks

Rated voltage 600V 450V, suitable for different regional power grid voltage standards

The maximum rated current of 20A 32A is determined based on the wire diameter and heat dissipation conditions

Maximum operating temperature 105 ° C T-Mark 85 ° C, suitable for high temperature environments (such as inside equipment)

Solid wire adaptation range AWG 24-AWG 12 0.2mm ² -4mm ² wire diameter correspondence: AWG24 ≈ 0.2mm ², AWG12 ≈ 4mm ²

Multi strand wire adaptation range AWG 24-AWG 12 0.2mm ² -4mm ² supports multi strand wires with twisted strands ≤ 36 strands

Flexible wire adaptation range AWG 24-AWG 12 0.14mm ² -4mm ² Suitable for fine twisted flexible wires (such as motor leads)

Contact resistance ≤ 5m Ω (initial value) ≤ 5m Ω (initial value) ensures low loss conductivity and reduces heat generation

Insulation resistance ≥ 100M Ω (500V DC) ≥ 100M Ω (500V DC) to ensure insulation performance and avoid leakage risk

3. Physical and mechanical properties

Shell material: transparent polycarbonate (PC), with high strength, impact resistance, and high temperature resistance characteristics;

Leverage material: Orange engineering plastic, with good mechanical strength and fatigue resistance (can be opened and closed repeatedly ≥ 100 times);

Conductive component material: high conductivity brass, surface treated with tin plating to enhance conductivity and oxidation resistance;

External dimensions (taking the 2-core model as an example): length x width x height ≈ 22mm x 12mm x 8mm (specific subject to the actual product);

Installation method: There is no fixed installation requirement, it can be freely placed in the junction box or fixed to the wiring harness with zip ties.

Product core advantages and competitive differences (compared to the 222 series)

Compare the core upgrade points of WAGO 221 series and WAGO 222 series (previous generation products) in terms of dimensions

The product has a small volume (reduced by 40% compared to the previous generation), which greatly improves space utilization and is suitable for narrow scenarios

Low operating force (lever operation is more effortless) reduces the manual intensity of batch installation to a moderate extent

The shell design is fully transparent, supporting visual inspection of semi transparent/opaque installation to enhance safety and facilitate quality control

The test slot is designed with dual front and rear test slots, with no directional restrictions and a single test slot. There are installation direction requirements to improve debugging convenience

Grip design with concave side grip area, no dedicated grip design, improved operational stability, and anti glove slippage

Installation and usage precautions

1. Installation steps

Wire processing: According to the connector identification requirements, strip the insulation layer of the wire (recommended stripping length 8-10mm, matching the length of the internal wiring terminal of the connector);

Leverage opening: Pull up the orange lever of the connector to 90 °, and the internal clamping mechanism will open, entering the wire insertion state;

Wire insertion: Fully insert the processed wire into the corresponding wiring hole of the connector, ensuring that the metal core of the wire is completely in contact with the internal conductive components and there is no insulation layer extending into the wiring hole;

Clamping and fixing: Press the lever down to the closed state, and hearing a "click" sound indicates that the clamping is in place and the wire is reliably fixed;

Visual inspection: Confirm through the transparent shell that the wire insertion depth and stripping length are compliant, and there is no exposed core wire or insulation layer clamping situation;
