Series E3PT
Three-Phase Output to 50A 520 Vac
Touch-Proof, AC or DC Control
FEATURES/BENEFITS
• Designed for all types of loads
• Tight zero-cross window
• Control LED on all models
• Internal output transient protection
• Touch-proof
DESCRIPTION
The Series E3PT three-phase solid-state relays are
designed for all types of loads. 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
APPROVALS
Series E3PT relays are pending UL recognition.
