NOTES
1) Line Voltage (nominal): 48 = 480 Vac
2) Switch Type: D = Zero-cross turn-on
A = AC control, Zero-cross turn-on
3) H = High surge capability
*Current limited to 50A due to terminals
DESCRIPTION
The Series E3PT three-phase solid-state relays are
designed for all types of loads. The E3PT relays
include as a standard a control LED for visual status.
The E3PT series is touch-proof for user safety. An
internal MOV and snubber circuit protect the output
thyristor. The E3PT relays are highly immune to large
current surges. The tight zero-cross window provides
a low EMI level. The E3PT relays are an excellent
choice for three-phase applications.
