NPT-Sealed High-Current Feedthrough Studs, 105 to 750 A
105–750 A · 5000 VAC · leak < 1 × 10⁻⁸ Pa·m³/s
Custom High-Current Power Feedthroughs
Designed to your vessel · 450–750 A examples · to +170 °C
Besides the standard studs, we design power feedthroughs to your wall thickness, thread, current and temperature. Two examples: a 750 A O-ring sealed stud with M33 × 2 body thread, and flange-mounted crimp feedthroughs for 450 A and 600 A with PPS insulating covers, rated to +170 °C and 5000 VAC.
