LP24 3-Pin Waterproof Solder Connector
2. Soldered joints. Not crimped, not screwed. They don't work loose when the motor shakes.
3. Third pin is the ground. Skip it on a wet pump station and you've got a problem.
4. IP68. Tested at 2 meters for 24 hours. Splash ratings don't cut it outdoors.
5. Takes 4mm² (12 AWG) cable, 14mm outer diameter. Power-class wire only.
6. Metal thread on the coupling, plastic elsewhere. Light enough, tough enough.
7. Field re-termination needs a soldering iron — if you want tool-free, go with our screw-lock LP24.

LP24 3-Pin Waterproof Solder Connector – 25A Three-Phase Connection, IP68 Sealed
Three-phase motors don't forgive a bad connection. The LP24 3-Pin Waterproof Solder Connector is built around that fact — 25A per contact, 400V, soldered terminals, and IP68 sealing. Three pins for three phases, or L/N/PE. One job: keep the connection stable when the equipment shakes and the environment is wet.
LP24 3-Pin Waterproof Solder Connector – Why Three-Phase Equipment Needs a Soldered Joint
Here's the thing about three-phase loads. The current is spread across three lines, and if one contact has higher resistance than the others, that phase runs hotter. A pump or a small motor that vibrates will work a crimped or screwed terminal loose over time — sometimes slowly, sometimes fast. The LP24 3-Pin Waterproof Solder Connector sidesteps that entirely. You solder the joint once, and it doesn't back out. No torque spec to check. No crimp die to calibrate.
The 3-pin layout gives you three phases or L/N/PE. For three-phase gear, that third pin isn't just "one more line" — it's the ground path. If you're running a motor in a wet location, that ground connection needs to be as solid as the power lines.
Where the Water Comes In
Three-phase equipment tends to live outdoors or in washdown areas — pump stations, outdoor HVAC units, agricultural irrigation. And yeah — these are the spots where water gets in. The LP24 3-Pin Waterproof Solder Connector handles IP68 at 2 meters, 24 hours. Cable entry takes 4mm² (12 AWG) with a 14mm outer diameter.
The housing is metal on the coupling thread where it takes the wear, plastic everywhere else to keep the weight down. The metal thread resists stripping when someone overtightens it in the field — a problem that comes up more than you'd think on three-phase installations.

Where Three-Phase Equipment Actually Uses This Connector
Sub-7.5kW three-phase motors. Deep-well irrigation pumps. Outdoor HVAC compressors. Marine three-phase equipment. Construction site distribution boxes. Anywhere you've got three phases running into equipment that gets wet, and a loose contact would mean a hot phase and a service call.
Every batch gets a dielectric test and a waterproof check. Solder joints get pull-tested, not just eyeballed.
Quality Control and Certifications
The LP24 series carries TUV, CE, and RoHS. We run ISO9001:2015, so material sourcing is consistent and production records are traceable. And the quality system actually gets audited — not just claimed.
Quick Questions We Get Asked
Q: Why solder for three-phase but screw terminals for 2-pin?
A: It's about vibration, not pin count. Three-phase motors and pumps shake more than a DC power run. Solder stays put.
Q: Can I run L/N/PE on this instead of three phases?
A: Yes. The 3-pin layout handles either. Grounding rules vary by region — check your local code.
Q: What's the difference between IP68 and IP67 for a wet pump station?
A: IP67 handles splashes and short immersion. IP68 handles continuous immersion. Pump stations fall into the second category.
Q: What cable size does it take?
A: 4mm² (12 AWG) with a 14mm outer diameter. Power-class cable, sized for the 25A rating.
