Series E3PT Three-Phase Output to 50A 520 Vac Touch-Proof, AC or DC Control Part Number Description E3PT48D12 12A, 520 Vac E3PT48A12 12A, 520 Vac E3PT48D50 50A*, 520 Vac E3PT48A50 50A*, 520 Vac E3PT48D50H 50A*, 520 Vac E3PT48A50H 50A*, 520 Vac FEATURES/BENEFITS E3PT 48 D 50 H Designed for all types of loads Tight zero-cross window Control LED on all models Internal output transient protection NOTES Touch-proof 1) Line Voltage (nominal): 48 = 480 Vac 2) Switch Type: D = Zero-cross turn-on A = AC control, Zero-cross turn-on DESCRIPTION 3) H = High surge capability The Series E3PT three-phase solid-state relays are *Current limited to 50A due to terminals designed for all types of loads. The E3PT relays include as a standard a control LED for visual status. MECHANICAL SPECIFICATION The E3PT series is touch-proof for user safety. An 3.26 (82.7) internal MOV and snubber circuit protect the output M4 .75 .75 (19) (19) 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.
