**[Raad two-phase miniature switch 63 ampere type C] (https://www.automation24.ir/product-395/%25DA%25A9%25D9%2584%25DB%258C%25D8%25AF-%25D9%2585% 25DB%258C%25D9%2586%25DB%258C%25D8%25A7%25D8%25AA%25D9%2588%25D8%25B1%25DB%258C-%25D8%25B1%25D8%25B9%25D8%25AF-%25D8%25AF% 25D9%2588-%25D9%2581%25D8%25A7%25D8%25B2-63-%25D8%25A2%25D9%2585%25D9%25BE%25D8%25B1-%25D8%25AA%25DB%258C%25D9%25BE-c )**\r\n\r\n\r\nRegarding the 63 amp miniature switch, it can be said that the miniature is a protective device that is used in electrical equipment and circuits to cut off the circuit when the current exceeds the permissible limit so that other equipment is not damaged.\r\n\r\nMiniature keys use two mechanisms for their operation.\r\n\r\nBitmal function for overload protection\r\nMagnetic function for short circuit protection\r\nThe miniature switches of Raad company are divided into 4 parts, single-bridge, double-bridge, three-bridge and four-bridge, in terms of the number of bridges, and in terms of the cut-off time, they are divided into fast-acting and slow-acting states. They are also divided into K, D, C, B and Z types in terms of application.\r\n\r\n## Type B miniature switch: This type of miniature switch is mostly used in the home and cuts off the overload current between 3 and 5 times the nominal current in a certain time. These types of switches are considered fast-acting.\r\n## Type C miniature switch: This type of switch is mostly used in industry and cuts the overload current between 5 and 10 times the rated current in a certain time. This type of switch is considered a slow-acting type.\r\n## D-type miniature switch: this type of switch is mostly used in special industries such as transformers and cuts the overload current 10 to 20 times the rated current.\r\n## K type miniature key: this type of key is used in transformer and engine. It is usually between types C and D.\r\n## Z-type miniature switch: This miniature will issue a shutdown command at a specific time when the passing current exceeds the rated current. This key is used in very sensitive circuits.\r\n\r\n\r\n**[Click here to view Raad products.](https://www.automation24.ir/product/list/search/?manufacturer_id=7&pageItems=120)**\r\n\r\n\r\nNote: accessories can be installed on the miniature keys to detect the on and off status or alarms.\r\n\r\n \r\n \r\n### Points to consider when buying a miniature key:\r\n### \r\n### Thumbnail key workflow\r\n### type of miniature key (depending on the place of use)\r\n### Accessories\r\n### The number of its bridges
