FEATURES/BENEFITS
The Series SD dual-phase relays are designed for all types of loads. The design
incorporates two relays in a single package. The relays utilize optical isolation to
protect the control from load transients. High-current models are excellent for motor
and phase angle control. The 50A 600 Vac models are available with common control
connector or individual control connector. Applications include motor control, heating
control, uninterruptible power supplies, light dimmers, industrial and process control,
and on/off controls of AC equipment. UL recognized. UL File Number: E285555.
Designed for all types of loads
Dual output (two relays in one package)
Faston terminals
Connector for common or individual control
Tight zero-cross window for low EMI
High immunity to surges
