{"product_id":"syr-wasserstandbegrenzer-933-1-dn20-mit-verriegelung","title":"SYR Water Level Limiter 933.1, DN20 with lock","description":"The water level limiter 933 serves to protect boilers in hot water heating systems against overheating 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 water shortage. 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 360° and replaced without draining the system. The water level limiter 933.1 locks after shutdown. Once the fault has been rectified, the system is switched on again using the unlock button on the water level limiter.\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: 1-pole changeover switch\u003cbr\u003e Installation position: main axis vertical\u003cbr\u003e Switch rating: 10 (4) A \/ 250 V AC\u003cbr\u003e TÜV component marking no.: TÜV - HWB - 16-190\u003cbr\u003e VDE identification no.: 139223","brand":"Sasserath","offers":[{"title":"1","offer_id":56543052136834,"sku":"WCW-0175847-001","price":365.44,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/3675\/7890\/files\/5_0_0_2_5002689de8ff63302275e42162a8f6c89d9dc0f3_wcw_0175847_gl_image2_converted_500x500_syv_093320000_jpg.jpg?v=1775779249","url":"https:\/\/shop.we-connect.work\/en\/products\/syr-wasserstandbegrenzer-933-1-dn20-mit-verriegelung","provider":"weconnectwork","version":"1.0","type":"link"}
