LP24 3-Pin Screw Terminal Waterproof Connector

LP24 3-Pin Screw Terminal Waterproof Connector – 10A Field-Wired Connection with IP68 Sealing

Three-phase power doesn't always need a soldering iron. The LP24 3-Pin Screw Terminal waterproof connector is the field-wireable version of our 3-pin line. 10A per contact, 400V. You tighten the screws with a screwdriver — no soldering iron needed. IP68, so water isn't an issue. Three pins for three phases, or L/N/PE. Whatever you're running, it stays put when the equipment shakes.

LP24 3-Pin Screw Terminal Waterproof Connector – Why Screw Terminals Matter in Three-Phase Work

Here's the thing about field installations. Not every job site has a soldering iron, and not every tech is trained to use one. The LP24 3-Pin Screw Terminal Waterproof Connector does away with all that. Strip the wire, push it in, tighten — that's it. The clamp grips 1.5mm² (16 AWG) cable tight. And the cable gland takes the pull, so the contact points don't have to.

Small three-phase loads — small motors, control panels, sensor arrays — get wired up on site and then forgotten about for years. That's what this one's for. The screws don't rattle loose the way crimped joints can. And if you ever need to redo a termination, just loosen, adjust, tighten.

Where the Water Comes In

Three-phase equipment lives outdoors or in washdown areas — pump stations, outdoor HVAC units, agricultural irrigation. And these are exactly the places where moisture finds a way in. The LP24 3-Pin Screw Terminal Waterproof Connector handles IP68 at 2 meters for 24 hours. Cable entry takes 1.5mm² (16 AWG) wire with a 7–9mm outer diameter.

Metal on the coupling thread — that's where it takes the beating. Plastic everywhere else, keeps the weight down. And the metal thread? Doesn't strip easy when someone cranks it too hard in the field.

Technical Specifications at a Glance

Where Three-Phase Equipment Actually Uses This Connector

Smaller three-phase loads that need field wiring. Control panels. Sensor arrays. Small pumps. Outdoor HVAC units. Agricultural irrigation controls. Anywhere you've got three phases running into equipment that gets wet, and you need to wire it up without a soldering iron.

Every batch gets a dielectric test and a waterproof check. Screw terminals get torque-checked, not just eyeballed.

Quality Control and Certifications

The LP24 series carries TUV, CE, and RoHS certifications, and we run under ISO9001:2015. Consistent material sourcing, traceable production records, and a quality system that gets audited.

Quick Questions We Get Asked

Q: Why screw terminals instead of solder for this version?

A: Field wiring. Not every job site has a soldering iron. Screw terminals let you terminate 1.5mm² cable with a screwdriver, and the clamp holds tight under vibration.

Q: What cable size does it take?

A: 1.5mm² (16 AWG) with a 7–9mm outer diameter for power, or 4–6.5mm for signal cable.

Q: Can I use it for L/N/PE instead of three phases?

A: Yes. The 3-pin layout handles either. Check your local code for grounding rules.

Q: Is IP68 enough for continuous submersion?

A: Yes. IP68 covers continuous immersion. We test at 2 meters for 24 hours.
