What does a transfer switch do, and why do i need one? A transfer switch is the link between your backup generator, the utility company, and Your home or business. It's job is to safely connect your home or business to Your backup generator during a power outage. A properly installed transfer switch Will isolate your generator from the utility company's power lines, protecting The power companies workers from harm. A transfer switch is required by law in All 50 states, and is an essential piece of safety equipment. 1) applicable to automatic transfer for main power supply and reserve supply of feed system or automatic transfer and security isolation of two load equipment 2) integrates switch with logic control as a whole, if without logic control, an additional controller is provided 3) realize selected mechanical integration possessing of voltage inspection, communication interface, electric and mechanical interlock 4) can actualize automatic, electric long range and emergency manual control
Model number: yeq2c Detailed product description Yeq2 series intelligent dual power automatic switch two or three poles and four pole mccb annex (supplementary the police contact), the mechanical interlocking transmission, intelligent controller and other components. It has the integral style and split type two kinds mechanism. Integral controller is equipped with a base and executing agencies; split type is intelligent controller installed in the panel , installed user base by implementing agencies to install the counter body controller with the implementing agencies with about 2m long cables. The body of the intelligent system consists of such accessories as dedicated positive/negative electromotor, breaker, fire control tripping, mechanical interlocking, aviation plug and connector terminal. All components are installed on the same metal sheet. The intelligent system (400vac 50/60hz working voltage) is provided with the function of mechanical-electrical interlock protection to guarantee safe and reliable power supply for you. Functions:1. The automatic controller can measure the voltages of both circuits at the same Time. When the supply voltage is higher than 115% of the rated value, it judges As over voltage; when it is lower than 60% ~ 80% (preset by user) of the rated voltage, It judges as under voltage. The microcomputer judges and processes the measuring Results and then sends out corresponding orders as switch-off, switch-on, generation, Unloading and alarming.
Model number: yeq2f (split type) Automatic transfer switches - function: power automatic transfer and overload and short circuit protection - performance: the time delay of transfer time is adjustable and action time is accurate - usage: mainly used in the two-path load field as in hospital, shopping center, Bank, and chemical industry, metallurgy and military facilities - structure: compact in structure, small in volume, high breaking and short arcing - current: 10a~800a - frame current: 63, 100, 225, 400, 630, 800 number of pole: 3p, 4 p - standards: comply with iec 947-6 What's the difference between a manual transfer switch and an automatic unit? with a manual transfer switch, when the power goes out, you need to start your generator, and connect it to the transfer switch. You then need to switch your house over to generator power. When the utility power is restored you need to switch your house back to utility power, and turn off your generator. With an automatic transfer switch, everything is fully automatic. When the utility power goes out, the transfer switch signals your generator to start. Once the generator is running the transfer switch automatically connects your home or business to the generator. When the utility power is restored, the transfer switch reconnects your home or business to the utility. Then it turns off your generator and waits patiently for the next power outage.
