4PRO ATS-100A-4P-i Automatic Transfer Changeover Switch, 4 Pole, 100A, 120/208V, 50/60Hz, 2-3 Phase

4PRO ATS-100A-4P-i Automatic Transfer Changeover Switch, 4 pole, 100A, 120/208V, 50/60Hz, 2-3 phase The ATS-100A-4P-i changeover switch is an microprocessor based intellectual device designed to transfer loads automatically and manually from one power source to another in a wide variety of 2-3 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 voltages within preset limits. Device has a manual load switch lever, a manual/auto mode switch and a mechanical locking. 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 positions. External display shows phase voltages (phase-phase), current workign mode and etc. It can be placed in a distance of 1-3 meters from the device via standard Ethernet cable. Power source voltage limits, transfer-, start- and stop delays and transfer modes are front panel configurable. Note: The delays apply only in case if the device is connected to 24VDC auxiliary power supply. Features  compatible with 120/208VAC 3 phase and 120/240 2 phase 50/60 Hz applications;  displays phase-phase voltages and current state on external LCD Display;  3 working positions: main power ON - backup power OFF; main power OFF - backup power ON; main and backup power OFF;  double complex contacts/ horizontal pulling mechanism/micro motor energy pre-storage and microcomputer control technology;  reliable mechanical interlock and electric interlock;  "Zero Position" technology. Device can be set to Zero Position under emergency situations with two way power supply cut off meeting the fire linkage requirements;

• Works with any contactors and changeover switch types
