ACV 10800276 kit elemento calefactor BL 9kW LCA DN400

This is a kit heating element rated at 9 kW with a DN400 flange. The "BL" and "LCA" designations are internal series codes from the manufacturer; no further decoding is provided in the catalogue data. The article is listed under heating elements and carries the brand ACV and article number 10800276. Heating elements of this class are immersion-type devices that convert electrical energy into heat, typically installed in a boiler vessel, thermal store, or hot water tank. The element sits inside the water volume and is controlled by a thermostat or a boiler control that switches the power on and off to maintain the set temperature. For a 9 kW element the power draw requires a suitable contactor and a correctly sized cable from the mains supply. When replacing such an element, the key selection parameters are the power rating (kW), the flange size (DN400 in this case, referring to the nominal diameter of the bolted flange), the heating element material, and the immersion length. The flange must match the counter-flange on the vessel, and the gasket should be renewed at replacement. Ensure that the voltage (typically 230 V or 400 V three-phase) matches the control circuit and that the thermostat sensor pocket is compatible with the element design. Do not assume that all 9 kW elements share the same immersion depth or terminal configuration. Always verify the physical fit against the existing installation.
