The switch is housed in a grey powder-coated metal clad enclosure measuring 81mm square with a 54.8mm depth, designed for surface mounting in workshops, plant rooms, service areas and shared commercial spaces where secure control of high-draw appliances is needed.\u003c\/p\u003e\n\u003cp\u003eThe double pole switching isolates both live and neutral lines when turned off, providing a higher level of isolation than single-pole switches for equipment such as water heaters, air conditioning units, and workshop machinery rated up to 20A (4,600W on 230V). The key lock operates in both the on and off positions, with two keys supplied allowing one to be held by facilities management while the other remains with the on-site team.\u003c\/p\u003e\n\u003cp\u003eThe premium-grade steel enclosure is powder-coated to resist surface wear and minor impacts in industrial and semi-industrial environments. The IP20 rating makes this switch suitable for dry indoor locations where dust and moisture are not present. The unit carries earth terminal connections and is certified to EN 60669-1, with Knightsbridge backing it with a 25-year guarantee.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e81mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e81mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e54.8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction\u003c\/td\u003e\n\u003ctd\u003ePremium grade steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003ePowder-coated Silver\/Grey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIP Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eClass\u003c\/td\u003e\n\u003ctd\u003eI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Voltage\u003c\/td\u003e\n\u003ctd\u003e230V 50Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEarth Terminal\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e25 Year Guarantee\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/datasheet-M8341L.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat equipment is this switch suitable for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis 20A switch is rated for loads up to 4,600W on 230V mains.
