Take the SEL Challenge

Can other manufacturers' equipment stand up to SEL testing levels?

	Industry Practice	SEL Certified	SEL Margin
ESD	6 kV Direct/8 kV air	8 kV, 15 kV	12 kV, 17 kV
Hipot	1.5 kV	2.5 kV	3 kV
Temp Range	-20 to 70°C	-40 to 85°C	-45 to 90°C
EFT	2 kV, 5 kHz	4 kV, 2.5 & 5 kHz	4kV, 100 kHz
Magnetic Field	30 A/m Cont. 300 A/m 3 sec.	100 A/m Cont. 1000 A/m 3 sec.	120 A/m Cont. 1200 A/m 3 sec.

ESD—Electrostatic Discharge, Hipot—Dielectric Strength,
EFT—Electric Fast Transient

SEL relays are tested above and beyond IEEE and IEC standards. Testing above the minimum requirements provides confidence to customers in SEL product reliability and durability. Using standards that are above industry average allows SEL to offer an unprecedented ten-year warranty.
