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 protection is provided internally on certain models. The Series E3P utilizes optical isolation to protect the control from load transients. High-current models are excellent for motor control. APPLICATIONS • Heating control • Motor control • Uninterruptible power supplies • Light dimmers • Three-phase industrial and process control • On/Off controls of AC equipment APPROVALS All models are UL recognized. UL File Number: E128555.
