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.
Features
- High density silver-alloy contacts providing thousands operating cycles at 100% rated load;
- Bridge type double break design not requiring special SCPD and matching AC-33B requirements;
- Optimized magnetic blow-out arc extinquish system allowing to reach 10le capacity;
- Multi-mode operation including manual transfer, automatic transfer with/without autorecovery and
- generator control under various configuration settings;
- 3 working positions: main power ON - backup power OFF; main power OFF - backup power ON; main and backup power OFF;
- Microprocessor controlled operations;
- 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 fighting linkage requirements;
- Singleness motor drive providing smooth, reliable, low noise operation;
- Driving motor energized during switching operations only and having outstanding energy saving;
- Mechanical interlock, making sure that the Normal power and Reserve Power sources work without
- interference;
- Distinct ON and OFF positions and activity indicators;
- Electromechanical integration design with accurate changeover adopting an advanced logical control technology and high anti-interference ability;
- Easy installation using control circuit plug type terminal connections.
Performance
1, Double complex contact, horizontal and vertical type frame basically, it have come to "Zero" arc(no arc chute);
2, Reliable machine interlock and elecric interlock, the executive
union parts adopt independency overload disconnect switch,
it makes more reliable and safety.
3, "zero" techinique, can force to set"zero" under emergency situation(break off two ways power supply at the same time).Meet the requirement of the fire protection linkage.
4, Operate overload disconnect switch change over adopt singless
electromotor drive, switch over smooth and reliable, no noise,
little wallop
5, Operate machine drive motor use only under the executive overload disconnect switch change over instanecus current across, outstanding energy saving.
6, Perform overload disconnect switch with mechanism interlock
device. It ensure the common use, standby power working
reliable and not interference.
7, Distinct on and off position indicator, padlock function et.c safe realize the isolator between electric power and overload
8, High security, high automatization, high retiablility, use life more than 8000 times
