FEATURES/BENEFITS
• Three-phase output
AC or DC control
Internal output protection
Control LED on all models
Designed for all types of loads
Excellent thermal performance
Tight zero-cross window for low EMI
High immunity to surges
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/O controls of AC equipment
APPROVALS
All models are UL recognized.
UL File Number: E128555.
