SPL-82 Quick Wire Connector Terminal Block

SPL-82 Quick Wire Connector Terminal Block provides a modern, efficient solution for making secure electrical connections without the need for traditional soldering or messy electrical tape. This 2-input 8-output lever-operated connector simplifies complex wiring tasks by allowing users to distribute power from a single source to multiple branches instantly. Furthermore, the tool-free design utilizes a robust locking lever mechanism that ensures a high-contact force on every inserted wire. Consequently, it reduces installation time significantly while maintaining superior safety standards in both residential and industrial environments. Therefore, you should choose the SPL-82 for any project requiring organized, reusable, and reliable wire termination.

Key Features:

• Lever-Actuated Mechanism: The quick-release levers allow for rapid wire insertion and removal, making the connector completely reusable and easy to adjust.
• Flame-Retardant Material: Manufacturers use high-quality, insulated PA66 and PC materials to ensure the housing resists heat and prevents electrical fires.
• Space-Saving Design: This compact terminal block organizes multiple wire connections into a single neat unit, effectively reducing clutter inside junction boxes.
• Secure Clamping: The internal stainless steel circlip grips the wire tightly to prevent accidental pull-outs even under vibration.
• Test Port Integration: A dedicated built-in test hole allows technicians to check for voltage with a probe without dismantling the entire connection.

Technical Specifications:

Dimensions:

• Total Length: ≈ 39.5 mm
• Total Width: ≈ 48.5 mm
• Total Height: ≈ 14.5 mm
• Strip Length: 9 to 10 mm (Recommended insulation stripping distance)

Pinout and Wiring:

• Input Side (2 Ports): Connect your main power supply wires (Live and Neutral) to the two primary input ports.
• Output Side (8 Ports): Insert up to eight load wires to distribute the corresponding input signals across multiple devices.
• Operating Steps: First, lift the orange lever to the 90° position. Next, insert the stripped wire fully into the terminal. Finally, push the lever back down to lock the wire in place.
• Safety Note: However, always ensure that the total current draw of all combined outputs does not exceed the 32 A rated limit of the connector.

Commonly Used in:

• Junction Boxes: Standardizing connections within wall-mounted boxes for home or office wiring.
• LED Lighting Installations: Splitting power from a single driver to multiple LED strips or spotlights.
• Control Panels: Organizing low-to-medium voltage signal distribution in industrial automation cabinets.

Applications:

• Home Improvement: Replacing old twist-on wire nuts for safer and faster light fixture installation.
• Prototyping: Providing a temporary yet secure way to connect power during the testing phase of electronic projects.
• HVAC Systems: Connecting thermostats and control units to various sensors and actuators.

Equivalent Models:

• Wago 221-412 / 221-415: However, these usually offer fewer ports per unit compared to the SPL-82 distribution model.
• PCT-218: A functionally similar 8-port lever connector often used in identical electrical applications.
• LT-822: A direct cross-reference part that provides the same 2-in-8-out configuration and current rating.
