250A 4 Pole Automatic Changeover Switch 230v Three Phase Changeover Switch

250A automatic changeover transfer switch mains power 4 Pole 230/400V 50/60Hz

• This changeover switch is an microprocessor based PC class device designed to transfer loads automatically and manually from one power source to another in a wide variety of 1-3 phase applications.
• The unit monitors 3-phase normal and reserve source voltages, sends remote start command to the generating set and performs changeover switching between those 2 sources connecting the load circuits to a power source having voltage and frequency within preset limits.
• Device has a manual load switch lever, a manual/auto mode switch and a mechanical locking switch.
• Inputs and outputs: fire linkage control, generator remote start, external indicators.
• The front panel leds provide information about mains and generator power availability as well as a current
• switch position.
• The device display control panel shows device current state and source voltages and frequences and can be placed on the switch front side or in a distance of 1-3 meters from the device via standard Ethernet cable.
• Power source voltage/frequency limits, transfer/start/stop delays, generator exerciser schedule and transfer modes are front panel configurable.
• Note: The delays apply in case if the device is connected to 24VDC auxiliary power supply only.
