This three-pole AC device handles main voltages from 20 to 600 V at 50–60 Hz and is rated for 35 A continuous operation, with an instantaneous release (N-release) of 455 A and an overload release (A-release) of 35 A, and it features screw terminals for straightforward wiring. Weighing about 2.263 kg, it is built for industrial environments with an insulation voltage of 1,000 V (pollution degree 3), a surge voltage resistance of 8 kV, and a mechanical\/shock tolerance of 25 g\/11 ms. Its electrical endurance is rated for roughly 25,000 cycles for main and auxiliary contacts, with a typical power loss of 14 W total (4.7 W per pole) at rated current. The unit supports operation from -20 to +60 C and storage from -50 to +80 C, with a storage\/humidity range of 10–95% RH and installation up to 2,000 m above sea level. In practice, 3RV2742-5FD10 is used in industrial control panels and machinery where UL 489\/CSA No.5-02-compliant protection is required, combining three poles of protection for the main circuit with screw-terminal connectivity and compatibility with standard S3-size motor protection schemes.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268139602154,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-industry-inc-3rv2742-5fd10-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
