High Power 1-in Multiple-Out Screw Terminal Block — 60A/400V | 80A/1000V | Cable Splicing Connector
A heavy-duty 1-in multiple-out screw terminal block for high-current power distribution wiring — connecting one incoming power cable to multiple outgoing circuits without junction boxes, wire nuts, or crimped splices. The screw terminal design provides secure, tool-tightened connections that resist vibration and thermal cycling, while the high-current ratings (60A/400V for 1–6mm² wire, 80A/1000V for 2.5–16mm² wire) cover the full range of industrial, commercial, and residential power distribution requirements. CE certified. Available in 4 models (ZK-306, ZK-316, ZK-506, ZK-516) with different input/output configurations.

| ZK-316 | 60A | 400V | 1–6mm² | 1 in, 3 out (larger) |
| ZK-506 | 80A | 1000V | 2.5–16mm² | 1 in, 5 out |
| ZK-516 | 80A | 1000V | 2.5–16mm² | 1 in, 5 out (larger) |
Why Screw Terminal Blocks for High-Current Splicing
| Method | Current Capacity | Reliability | Serviceability |
|---|---|---|---|
| Screw terminal block (this product) | Up to 80A | High (tool-tightened) | Excellent (re-enterable) |
| Wire nut / Wago connector | Up to 32A typical | Moderate | Good |
| Crimped butt splice | Rated for wire gauge | High (if correctly crimped) | Poor (destructive removal) |
| Soldered splice | Rated for wire gauge | High (if correctly soldered) | Poor (destructive removal) |

Frequently Asked Questions
Q: Can I use the ZK-506 (80A/1000V) for a 400V application?
A: Yes. A higher voltage rating is always safe for lower voltage applications. The ZK-506 rated at 1000V is suitable for 400V applications with additional safety margin.
Q: What screwdriver do I need?
A: Use a flat-blade screwdriver sized for the terminal screw. Tighten to the torque specified on the terminal block label (typically 1.5–3 Nm for this current range).
