De nuv\u00e6rende RITOKS MCB-modeller anvender en 35 mm DIN-skinne, mens den offentliggjorte MCCB-serie anvender panelmontering eller fast montering.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Kan jeg v\u00e6lge mellem MCB og MCCB udelukkende p\u00e5 baggrund af sp\u00e6ndingen?<\/summary>\n<p class=\"wp-block-paragraph\">Nej. Sp\u00e6ndingen er blot \u00e9n af flere udv\u00e6lgelseskriterier. Man b\u00f8r ogs\u00e5 tage h\u00f8jde for str\u00f8mstyrke, poler, monteringsform, den n\u00f8jagtige modelkonfiguration og anvendelseskravene.<\/p>\n<\/details>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Kr\u00e6ver et 250 A j\u00e6vnstr\u00f8mskredsl\u00f8b automatisk en MCCB?<\/summary>\n<p class=\"wp-block-paragraph\">Ikke n\u00f8dvendigvis.
