Specifications
• Designed to reduce conducted noise to
acceptable limits for equipment that must comply
with FCC / EN specifications
Maximum leakage current each Line to Ground:
3, 6 & 10A
@120 VAC 60 Hz:
@250 VAC 50 Hz:
VSK Models
.4 mA
ESK Models
.21 mA
.7 mA
.36 mA
• Utilizes significantly higher element values than
the general purpose K Series which makes them
better suited for equipment with Line to Ground
and Line to Line conducted emissions including
those with switching power supplies
20, 30 & 40A
@120 VAC 60 Hz:
@250 VAC 50 Hz:
.75 mA
1.25 mA
.3 mA
.5 mA
Hipot rating (one minute):
Line to Ground:
Line to Line:
2250 VDC
1450 VDC
• ESK6C and VSK6C incorporate separate ground
circuit inductor to isolate the equipment chassis
from power line ground at RF frequencies
Rated Voltage (max):
