Solid-state Relay Provides Three Operating
Functions in a Compact Package
• Prevents burnouts in 3-phase induction motors due to overcur-
• LEDs indicate operation of the selected operating function.
• Wide setting ranges: current: 1 to 160 A; operating time: 1 to
• Protects the motor from reversing without starting it.

... You cannot use reverse-phase protection if you use control power with single-phase operation. Connect to terminals 1 and 2 for single- phase operation. Also, make sure to turn OFF the reverse-phase setting on the function setting switches. An error will occur if the SE is used with the reverse-phase setting turned ON during single-phase operation. Reverse-phase is detected in order of phase1, phase2 and phase3 of control power ...
