Series E3PT Three-Phase Output to 50A 520 Vac Touch-Proof DC Control Part Number Description E3PT48D50 50A*, 520 Vac For RoHS Compliant Contact Factory Part Number Explanation E3PT 48 D 50 H 2 3 Series Switch Type High Surge 1 Line Voltage Output Current Amps FEATURES/BENEFITS NOTES Designed for all types of loads 1) Line Voltage (nominal) 48 = 480 Vac Tight zero-cross window 2) Switch Type: D = Zero-cross turn-on 3) H: High surge capability Control LED on all models *Current limited to 50A due to terminals Internal output transient protection Touch-proof MECHANICAL SPECIFICATION DESCRIPTION 3.26 (82.7) The Series E3PT three-phase solid-state relays are M4 .75 .75 designed for all types of loads. The E3PT relays (19) (19) 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. 3.58 (91) APPLICATIONS 3.94 (100) Heating control Motor control Three-phase industrial and process control APPROVALS Series E3PT relays are pending UL recognition.
