Automatic transfer switch 3P ABB S203-D16 16A 6kA 400V
ABB S203-D16 automatic transfer switches are a product of ABB S203 series of automatic transfer switches and belong to the System Pro M series. It has the function of current limiting and provides reliable protection against overload and short circuit. S203-D16 automatic transfer switches adopt two different tripping mechanisms: a slow thermal switching mechanism for overload protection and an electromagnetic tripping mechanism for short circuit protection. It has the characteristics of type D, rated working voltage of 400V AC, rated current of 16A, rated short-circuit capacity of 6kA, protective pole 3. In addition, it is suitable for DIN rail installation and can be used in domestic, commercial and industrial applications.
The features of the S203-D16 transfer switch include a wide range of rated operating voltage up to 440 VAC and up to 12 VAC and 12 VDC. This makes it ideal for a variety of electrical systems and equipment. In addition, it has good short-circuit capability, which allows the circuit to be quickly disconnected in the event of a fault, protecting the safety of equipment and personnel.
The S203-D16 automatic transfer switch has a compact structure, takes up little space and is suitable for installation in limited space. In addition, it has multiple configuration options, including 1P, 1P+N, 2P, 3P, 3P+N and 4P to meet different installation needs. It also has a shunt capacity of 6 kA and provides reliable protection at 230/400 VAC.
In addition to the above characteristics, the S203-D16 automatic transfer switch also has a lower accessory auxiliary contact, which can be installed on the S200, saving 50% space. This makes it more flexible and convenient for installation and maintenance.
In short, the ABB S203-D16 transfer switch is a powerful, safe and reliable electrical protection device for a variety of application scenarios. Its advanced features and reliability make it an ideal choice for electrical systems that can provide comprehensive protection for equipment and personnel. "
