Littelfuse Symcom Voltage Monitoring Relay, 3-Phase, Series: 355, 475 to 600 VAC, 50/60 Hz Frequency, SPDT/(1 Form C) Contact Configuration, Threaded Mounting, 2 to 30 s Trip Delay, 2.93 in H x 5.27 in W x 2.95 in D Dimensions
UL 508 File No. E68520
Proprietary microcontroller based circuitry constantly monitors 3-phase voltage to protect against harmful line conditions, even before the motor is started|Advanced LED indication provides diagnostics which can be used for troubleshooting and to determine relay status|Adjustable trip and restart delay settings prevent nuisance tripping due to rapidly fluctuating power line conditions and allows staggered start up of multiple motors, after a fault, to prevent a low voltage condition|Combines protection and diagnostics|2 to 30 s adjustable trip delta time at low and high voltage and unbalance
