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/Off controls of AC equipment
APPROVALS
All models are UL recognized.
UL File Number: E128555.
