Miniature Automatic Transfer Switch ABB S203-D63 63A 3P 400V
ABB S203-D63 miniature circuit breakers are part of the ABB S200 series of miniature circuit breakers and belong to the System Pro M S200 series and have current limiting function. They have two different tripping mechanisms: one is a delayed thermal tripping mechanism for overload protection and the other is an electromagnetic tripping mechanism for short circuit protection. They have different characteristics (B, C, D, K, Z), configurations (1P, 1P+N, 2P, 3P, 3P+N, 4P), parallel connection capabilities (230/400V AC 6kA) and rated current (63A). ABB S203-D63 miniature circuit breakers can be used in residential, commercial and industrial purposes. An additional bottom accessory contact can be installed on the S200, saving 50% space.
The rated working voltage of ABB S203-D63 miniature circuit breaker is 400VAC, the input voltage is AC/DC, the maximum working voltage is 440VAC, the minimum is 12VAC and 12VDC. It has 3 protective poles, the installation type is DIN rail. The rated short-circuit capacity is 6KA, and it is suitable for various circuit protection needs.
The product's D characteristic indicates its tripping characteristics and is suitable for occasions where short-circuit protection is more demanding. The 63A rated current meets the rated current needs of most circuits. Three protective poles provide more complete circuit protection, ensuring timely circuit shutdown in the event of a failure and protecting the safety of equipment and personnel.
ABB S203-D63 miniature circuit breakers have a compact design and are suitable for limited installation space. The reliable tripping mechanism and high short-circuit rating make it an ideal choice for a variety of applications, including residential buildings, commercial buildings, and industrial facilities. Its reliability and safety have also been widely recognized and applied.
In short, the ABB S203-D63 miniature circuit breaker is a powerful, safe and reliable circuit protection device suitable for various circuit protection needs. Its advanced design and reliable performance make it a leading choice in the industry, providing users with comprehensive circuit protection solutions.
