3 Way Lever Wire Connector Terminal Block for CCTV Power Distribution

The 3 Way Lever Wire Connector Terminal Block for CCTV Power Distribution (3-WAY-TERMINAL-BLOCK-GREY) joins three conductors inside one insulated housing. Here is what each spec means on the job.

Spec to practice

• 3 ports: three wires meet at one point. A DC feed has two poles, so splitting one supply to two cameras needs one block on the positive side and one on the negative.
• Lever clamp: lift the lever, push the wire in, close it. No screwdriver and no crimping tool.
• Solid and stranded copper: you can join solid-core power cable to stranded pigtails in the same block.
• 12V DC and 24V DC: made for CCTV power distribution from a centralised power supply unit (PSU) to cameras. It also suits alarm wiring and low-voltage control circuits.
• Reusable: open the lever to pull a wire out and re-terminate it if a camera moves or a cable is rerouted.
• Compact insulated housing: sized for junction boxes, network cabinets and camera enclosures.

What else you need

A PSU that outputs 12V DC or 24V DC to match your cameras, and copper cable for each leg. Count your conductors first: this block takes three, so a larger split needs more blocks.

If a camera flickers or goes dark at night, look at the PSU rating and cable length first. Infrared (IR) LEDs draw more power after dark, and a weak supply or long run can cause voltage drop. The connector is rarely the cause.
