{"product_id":"5sy4163-5","title":"5SY4163-5","description":"Siemens' UL 1077 5SY4163-5 Supplementary Protectors are designed to provide additional protection along with a branch circuit protection device. Since these Supplementary protectors are made to trip faster than a standard UL 489 Circuit Breaker they are able to provide additional protection for more sensitive devices inside the panel. Supplementary protectors can be used in a number of industrial applications such as to provide selectivity for multiple motor control circuits on the secondary side of a control transformer or power supply by allowing the user to quickly find the problem circuit should a fault occur without having to shut down all of the other control circuits. Supplementary protectors may also be used as a local disconnecting means inside the panel when a branch circuit protection device is already present.\u003cbr\u003e\u003cbr\u003eThe trip curve A characteristic of the 5SY4163-5 is designed to protect extremely sensitive circuits, for example those involving semiconductors.  The magnetic trip point of these breakers is 2 to 3 times the I\u003csub\u003en\u003c\/sub\u003e rating.  The thermal trip point is 1.13 to 1.45 that of the protector rating.","brand":"Siemens","offers":[{"title":"Default Title","offer_id":48222146265326,"sku":"5SY4163-5","price":37.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/0802\/3790\/files\/5SY4163-5-2.jpg?v=1782784035","url":"https:\/\/www.imc-direct.com\/products\/5sy4163-5","provider":"IMC Direct","version":"1.0","type":"link"}
