{"product_id":"syr-wasserstandbegrenzer-933-2-dn20-ohne-verriegelung","title":"SYR Water Level Controller 933.2, DN20 without Interlock","description":"The water level limiter 933 is used to protect boilers in hot water heating systems from burnout due to lack of water. Installation is mandatory for closed heating systems according to DIN EN 12828 with a heating capacity of more than 300 kW. For boilers with a lower heating capacity, installation is mandatory if it cannot be ruled out that impermissible overheating may occur in the event of a lack of water. In addition, the water level limiter 933 can be used wherever water level-dependent electrical switching operations are to be triggered and a testing option without lowering the water level is required.\u003cbr\u003eThe water level limiter 933 is designed as a device with magnetic transmission of the float movement to a microswitch and allows testing without lowering the water level. The electrical switching unit can be rotated by 360° and replaced without draining the system. The water level limiter 933.2 does not interlock after switching off. An interlock must therefore be provided in the subsequent electrical circuit.\u003cbr\u003eTechnical data:\u003cbr\u003e Operating pressure: max. 10 bar\u003cbr\u003e Operating temperature: max. 120 °C\u003cbr\u003e Max. ambient temperature: max. 70 °C\u003cbr\u003e Protection class: IP 65\u003cbr\u003e Microswitch: changeover contact 1-pole\u003cbr\u003e Installation position: main axis vertical\u003cbr\u003e Switch contact rating: 10 (4) A \/ 250 V AC\u003cbr\u003e TÜV component identification no.: TÜV - HWB - 16-190\u003cbr\u003e VDE certificate no.: 139223","brand":"Sasserath","offers":[{"title":"1","offer_id":56543056822658,"sku":"WCW-0176047-001","price":481.84,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/3675\/7890\/files\/5_e_b_f_5ebf1bfd02e3062dd91c2d8954e9f630d5d285e8_wcw_0176047_gl_image1_converted_500x500_syu_093320000_jpg.jpg?v=1775779543","url":"https:\/\/shop.we-connect.work\/en\/products\/syr-wasserstandbegrenzer-933-2-dn20-ohne-verriegelung","provider":"weconnectwork","version":"1.0","type":"link"}
