{"product_id":"5sy4120-6","title":"5SY4120-6","description":"\u003cp\u003eSiemens' UL 1077 5SY4120-6 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.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":47772054224950,"sku":"hnq1789669431257","price":20.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0752\/0990\/0086\/files\/5sy4120-6_1.jpg?v=1789669440","url":"https:\/\/stainproofclad.shop\/products\/5sy4120-6","provider":"My Store","version":"1.0","type":"link"}
