Features&Advantages
Superior environmental protection prevents ingress of dust and water during submersion up to 1 meter.The twist-lock mechanism guarantees secure mating under vibration,
reducing accidental disconnections.High-temp thermoplastic resists impact and chemical degradation,extending service life in steel mills or wastewater plants.
Application Scenarios
Deploy in shipyards for shore power connections,construction sites with portable equipment,and food processing plants requiring washdown safety.Compatible with generators,CNC machines,and HVAC systems needing 30A/600V 3-phase power.Ensures OSHA and NEC compliance in hazardous locations.
Installation Guide
Cut a 42mm panel hole and secure with M40×1.5 threading(25–30 N·m torque).
Strip wires to 10mm,insert 6–10 AWG cables into color-coded terminals(L1/L2/L3/Green).
Tighten terminal screws to 1.2 N·m.Verify strain relief clamping before energizing.
Critical Precautions
Never exceed 30A continuous load—overcurrent risks terminal melting.Inspect seals quarterly for cracks compromising IP67 integrity.Avoid using near flammable gases
without explosion-proof enclosures.Always de-energize before disconnecting under load.
Q1:Is Eaton 400PJ30-7 compatible with 480V systems?
Yes,the 400PJ30-7 handles 480V systems effortlessly.Its 600V rating provides a 25%safety margin above standard industrial voltages.Ensure phase conductors use 10 AWG
copper wire to minimize voltage drop.Verify local electrical codes for specific installation requirements.
Q2:Can it withstand saltwater exposure?
Absolutely.The IP67 seal and corrosion-resistant PA66 housing prevent saltwater intrusion.Silver-plated contacts resist oxidation in marine environments.Rinse with fresh
water after submersion to remove salt residues prolonging lifespan.
Q3:What’s the difference between 400PJ30-7 and 400PJ30-7R?
The 400PJ30-7R variant features oil-resistant rubber seals for petroleum applications.Standard 400PJ30-7 uses thermoplastic seals suited for general industrial use.Both
share identical electrical specs but differ in chemical compatibility.
Q4:How to troubleshoot connection overheating?
Check for loose terminals or wire fraying causing resistance buildup.Measure load current—sustained draws above 30A demand upsizing.Inspect contact oxidation;clean
with electrical contact spray if discolored.Replace if housing shows thermal deformation.
Q5:Does it support 50Hz/60Hz power sources?
Yes,frequency independence makes it global-ready.Works with 50Hz(EU/Asia)and 60Hz(Americas)systems without derating.Ensure voltage stays within 600V AC maximum
regardless of frequency variations.
Q6:Can I use it with aluminum wiring?
Not recommended.Aluminum’s thermal expansion risks loose connections over time.Eaton specifies copper-only wiring(6–10 AWG)for reliable conductivity.If unavoidable
,apply antioxidant paste and retorque terminals annually.
Q7:Is a locking clip included?
No,locking clips(e.g.,Eaton C400 series)ship separately.These prevent accidental unlatching in high-vibration zones.Select clips matching your cable diameter for optimal
strain relief.
Q8:What’s the lifespan expectancy?
Rated for 10,000+mating cycles with proper maintenance.Lifespan halves in abrasive environments like mining.Replace if pins show wear or insulation resistance drops
below 100MΩper IEC 60309.
Q9:Can it be repaired or must it be replaced?
Terminal blocks are user-replaceable;damaged housings require full replacement.Eaton sells repair kits with terminals and seals.Never modify original parts—voids UL
certification and safety compliance.
