Littelfuse Symcom Phase Monitoring Relay, 3-Phase, Series: 201A, 190 to 480 VAC, 50/60 Hz Frequency, SPDT Contact Configuration, DIN Rail/Plug-In Mounting, 2.38 in W x 4.13 in D x 1.75 in H Dimensions
Additional Description: LTFS-201A 3-Phase Voltage/Phase Monitor Voltage (V): 190 to 480VAC SPDT
Catalog Description: The 201A is a 3-phase, auto-ranging, dual-range voltage monitor that protects 190-480VAC, 50/60Hz motors regardless of size. The product provides a user selectable nominal voltage setpoint and the voltage monitor automatically selects between the 200V and 400V range. The 201A includes advanced single LED diagnostics, where color and different light patterns distinguish between faults and normal conditions.This unique microcontroller-based voltage and phase-sensing device constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the 201A’s output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels.
