DESCRIPTION
The Series E3P three-phase relays are designed for all
types of loads. The design incorporates a thyristor output.
Control status LED is a standard on all models. Output
NOTES
protection is provided internally on certain models. The
1) Line Voltage (nominal): 48 = 480 Vac
Series E3P utilizes optical isolation to protect the control
2) Switch Type: R = Random turn-on; D = Zero-cross turn-on;
from load transients. High-current models are excellent for
A = AC control, Zero-cross turn-on
3) Features: -16 = MOV, -22 = 10-30Vac motor control.
