This CNC Electric listing is tracked in the project product data at Rs.1,500 for the 63A 3P DIN-rail version. It suits workshops, pump panels, generator boards, inverter bypass arrangements and compact utility DBs where the operator is expected to transfer source deliberately and safely.\u003c\/p\u003e\n\u003cp\u003eThe important point is this: this is a manual transfer device, not an automatic one. Its job is to let you choose one source, isolate at the center OFF position, and then move to the second source. In Pakistan, that matters in real settings where WAPDA supply, generator backup and inverter supply are all part of the same conversation. A neat DIN-rail form also helps when the panel builder wants the device inside the enclosure instead of sticking out like an external rotary plate switch.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3 pole manual changeover breaker for three-phase source selection\u003c\/li\u003e\n\u003cli\u003e63A local sale variant in the current project data\u003c\/li\u003e\n\u003cli\u003eDIN rail mounting for internal panel installation\u003c\/li\u003e\n\u003cli\u003e1-0-2 transfer logic for source one, OFF, and source two\u003c\/li\u003e\n\u003cli\u003eIEC 60947-3 switch disconnector class in the official YCBZ family\u003c\/li\u003e\n\u003cli\u003eBetter fit than EP type when the goal is compact internal mounting\u003c\/li\u003e\n\u003cli\u003eUseful for generator, inverter and utility source transfer in non-automatic setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\u003ctd\u003eDIN rail manual changeover breaker \/ switch disconnector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePole format\u003c\/td\u003e\n\u003ctd\u003e3 Pole\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLocal listed current\u003c\/td\u003e\n\u003ctd\u003e63A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated voltage family reference\u003c\/td\u003e\n\u003ctd\u003e240\/415V~\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated frequency family reference\u003c\/td\u003e\n\u003ctd\u003e50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact form\u003c\/td\u003e\n\u003ctd\u003e1-0-2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrical life family reference\u003c\/td\u003e\n\u003ctd\u003e1500 cycles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMechanical life family reference\u003c\/td\u003e\n\u003ctd\u003e8500 cycles\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProtection degree family reference\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmbient temperature family reference\u003c\/td\u003e\n\u003ctd\u003e-5°C to +40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN rail EN60715 (35mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3P width family reference\u003c\/td\u003e\n\u003ctd\u003e108 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal\/cable size family reference\u003c\/td\u003e\n\u003ctd\u003e50mm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThis description uses the local sale data currently available in the project files plus official YCBZ family technical references.
