SPL2/3/4/5 Quick Wiring Terminal – PCT Push-In Parallel Wire Connector, 1-in 2/3/4/5-Out Splitter for Lamp & Lighting

SPL series PCT (Push-in Connection Technology) quick wiring terminals for lamp and lighting circuit wiring. The push-in spring clamp mechanism accepts stripped wire without tools — insert the stripped wire end and the spring clamp locks it in place. The 1-in / multi-out design allows a single supply wire to be branched to 2, 3, 4, or 5 lighting fixtures without a junction box or wire nuts. Transparent housing allows visual verification of wire insertion. Compact size fits inside standard luminaire housings and junction boxes.

SPL vs Wago 221 — Quick Connector Comparison

• SPL (this product): Fixed-port parallel connector. All ports share the same circuit. Lower cost, compact. Best for permanent lighting branch connections.
• Wago 221 (lever-type): Individual lever per port for independent wire insertion and release. Higher cost, more flexible. Best for applications requiring frequent wire changes or mixed wire types.
• Selection rule: Use SPL for permanent lighting installations where cost and compactness are priorities. Use Wago 221 where individual port release is needed.

Frequently Asked Questions

Can I use SPL connectors for stranded wire?

Yes, with wire ferrules (end sleeves). Crimp an insulated wire ferrule onto the stripped stranded wire end before insertion. Without ferrules, individual strands can escape the spring clamp area, reducing contact area and increasing resistance. Solid wire can be inserted directly without ferrules.

How do I release a wire from an SPL connector?

Insert a flat-blade screwdriver (2–3mm width) into the release slot adjacent to the wire entry port. Press inward to depress the spring clamp, then pull the wire out. Do not pull the wire without depressing the spring — this deforms the spring clamp and reduces clamping force for subsequent insertions.

What is the maximum load for one SPL5?

SPL5 has 5 ports (1-in / 4-out), branching one supply to 4 fixtures. Total current must not exceed 24A. For LED lighting at 230V: 24A × 230V = 5520W maximum total load. A typical 10W LED downlight draws 0.043A — an SPL5 can supply 4 fixtures with significant current headroom. The limiting factor is usually the supply wire ampacity, not the connector rating.

Are SPL connectors suitable for outdoor use?

SPL connectors are designed for indoor and protected enclosure use — not IP-rated for outdoor or wet environments. For outdoor lighting branch connections, use IP-rated junction boxes with screw clamp terminals, or Wago 221 connectors in IP68-rated enclosures.

Typical Applications

• LED lighting: Branching LED driver outputs to multiple LED downlights and fixtures
• Luminaire wiring: Internal wiring connections inside light fittings
• HVAC: Control wiring branch connections in air handling units
• Building wiring: Junction box connections for lighting circuits
• Solar: DC wiring branch connections in indoor inverter installations
