FAQ
Q: What fault current and high-voltage tolerances does this industrial receptacle support?
A: This rugged assembly is engineered to withstand extreme field faults, passing two phase-through fault tests of 25.0kA for 0.2 seconds and two earth-through fault tests of 8.0kA for 0.2 seconds, with an AC high-voltage phase withstand rating of 8.6kV for one minute.
Q: What accessories are included to protect and install this receptacle body?
A: The unit features a protective silicone cover to shield live connection terminals from site dirt and moisture, and comes with a durable stainless steel hanging plate configured for back-to-back receptacle mounting
Complete your underground high-voltage system by pairing this crimp body with its corresponding heavy-duty industrial plug built for hazardous environments.
When planning heavy sub-station installations or field distribution runs, route your main high-amperage lines safely using our certified power cables.
For compact plant control panels or switchboard assemblies requiring flexible links alongside your main couplers, integrate a highly conductive flexible copper busbar to optimize your internal bus layout.
