| Series E3PT Three-Phase Output to 50A 520 Vac Touch-Proof, AC or DC Control Part Number E3PT48D12 E3PT48A12 E3PT48D50 E3PT48A50 E3PT48D50H E3PT48A50H Description 12A, 520 Vac 12A, 520 Vac 50A*, 520 Vac 50A*, 520 Vac 50A*, 520 Vac 50A*, 520 Vac E3PT 48 D 50 H 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 FEATURES/BENEFITS * Designed for all types of loads * Tight zero-cross window * Control LED on all models * Internal output transient protection * Touch-proof 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. APPLICATIONS * Heating control * Motor control * Three-phase industrial and process control APPROVALS Series E3PT relays are pending UL recognition.
