SE-K1EN Omron

Motor Protective Relay SE CSM SE DS E 8 2 Solid-state Relay Provides Three Operating Functions in a Compact Package Prevents burnouts in 3-phase induction motors due to overcurrent, open-phase, or reverse-phase. LEDs indicate operation of the selected operating function. Wide setting ranges: current: 1 to 160 A operating time: 1 to 40 s. Protects the motor from reversing without starting it. The SE cannot be used with circuits with distorted waveforms, inverter circuits, or capacitor loads. Model Number Structure Model Number Legend SE-K N 12 3 4 5 6 7 8 1. Basic model name 5.

Product history P: Plug-in type N: New version None: Flush mount type Note: A 3-phase transformer (sold separately) must be used to operate Plug-in Relays at 380, 400, 415, or 440 VAC. Drop the primary voltage (380 to 440 VAC) to a 200-VAC secondary voltage before applying it to the SE-KP2EN or SE-KQP2EN.
