Specifications

Maximum leakage current at 10% unsymetrical mains (3 Phase WYE Center Tapped) Each line to ground:
	@ 120 VAC 60 Hz	5.0 mA
	@ 250 VAC 50 Hz	9.6 mA

Hipot rating (one minute):
	line to ground	2210 VDC
	line to line	2158 VDC

Operating Frequency:		50 / 60 Hz

Rated voltage (max.):
	phase to phase	480 VAC
	phase to ground	277 VAC
