Designed for front-plate mounting, it pairs with Siemens 3SB3 pushbuttons and related signaling devices to add a compact two-contact auxiliary channel in control panels. It is rated for insulation voltage up to 400 V and supports a thermal current of 10 A, with an impulse voltage withstand of 4 kV, making it suitable for standard signaling and interlock circuits in industrial equipment. The two contact elements in a single module provide NO\/NC signaling without the need for a separate relay, and the screw-terminal connections offer secure, durable wiring in harsh environments when used with compatible front-plate assemblies. Typical applications include signaling, status indication, and interlocking in machine control panels, where a compact auxiliary contact block is required for Siemens 3SB\/SIRIUS signaling devices.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268146516202,"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-3sb3400-0a-contact-block-with-2-contact-elements","provider":"GTG Hardware","version":"1.0","type":"link"}
