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 3.94 (100) 2.22 (56.5) APPROVALS Series E3PT relays are pending UL recognition.
