LP28 3-Pin 32A Circular Power Connector

LP28 3-Pin 32A Circular Power Connector – High-Current Three-Phase Connection with IP67 Sealing

Three poles. Thirty-two amps each. The LP28 3-Pin 32A Circular Power Connector handles a full three-phase load through one sealed shell — 500V working voltage, 10mm² cable, and screw terminals you tighten on site. No crimp lugs, no special tools. Just strip, insert, tighten, done.

LP28 3-Pin 32A Circular Power Connector – Built for Three-Phase Power in Wet Conditions

Three-phase work means three separate current paths. When one contact has higher resistance than the others, that phase runs hotter. A stiff 10mm² cable makes it worse — it puts torque on the coupling every time it moves. The LP28 3-Pin 32A Circular Power Connector handles both problems: a metal coupling thread for the torque, and screw terminals that stay tight under vibration. Plastic everywhere else to keep the weight sane.

The cable gland anchors the wire separately from the contact points. Pull force never reaches the terminals. Cable entry takes 16.5 to 18.5mm outer diameter — the class of cable you need for 32A anyway.

Sealed for the Real World, Not the Lab

IP67 sealing holds up to rain, washdown, and short-term immersion. Not IP68, and that's a deliberate spec — IP67 is what most field power applications actually see, and it keeps cost where it belongs. The housing is metal on the coupling thread where the wear happens, plastic elsewhere.

We've seen these end up on three-phase motors, pump controls, outdoor HVAC units, agricultural irrigation panels, and marine power distribution. Places where you've got 32A per phase running through one connection and a wet floor underneath.

Technical Specifications at a Glance

​​​​​​​Where This 3-Pin Connector Actually Gets Used

Three-phase runs in wet environments. Small industrial motors. Pump station controls. Outdoor HVAC compressors. Agricultural irrigation panels. Marine power distribution. Construction site distribution boxes. Anywhere you need three phases through a connection that gets wired on site and left alone — and that's where the LP28 3-Pin 32A Circular Power Connector ends up.

Every batch gets a dielectric test and a waterproof check. Screw terminals get torque-checked, not just eyeballed. It costs us time. It saves you callbacks.

Quality Control and Certifications

The LP28 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: Can I use this for single-phase plus ground?

A: Yes. The 3-pin layout handles three-phase or L/N/PE. Check your local code for grounding rules.

Q: What cable size does it take?

A: 10mm² with a 16.5 to 18.5mm outer diameter. That's the class of cable you need for 32A per phase.

Q: Why IP67 instead of IP68?

A: IP67 covers rain, washdown, and short-term immersion — which is what most three-phase field power applications actually see. IP68 would add cost for continuous submersion. If you need it, talk to us.

Q: Can I re-terminate in the field?

A: Yes. Loosen the screw, adjust, re-tighten. No wasted lugs, no wasted connector.
