355-400-5 - SymCom 3-Phase Voltage Monitor 380-480V Adjustable VUB TD RD 2x480V Relay

The Model 355 Family
The Model 355 is a 3-phase voltage monitor with adjustable trip and restart delay, adjustable voltage unbalance and multiple diagnostic lights.It is perfect for heavy-duty applications that need both protection and simple user-friendly diagnostics. Applications include pump panels, commercial HVAC, oil rigs and others.

The Model 355 uses microcontroller technology to monitor incoming voltage and de-energize its output relay if power problems exist. The Model 355 can protect motors from damage caused by single-phasing, high and low voltage, phase reversal and voltage unbalance. It has four diagnostic LEDs that clearly show overvoltage, undervoltage, voltage unbalance, reverse-phase and normal conditions.

The Model 355-200 is equipped with a heavy-duty 10A general purpose SPDT relay. The Model 355-400 and 355-600 are equipped with a 470VA @ 600VAC pilot duty SPDT relay. A high voltage (600V) DPDT relay output option is available with the 400V model.
