{"id":341,"text":"Earth Fault Relay","nick":"VR9030B - Ground Fault Relay","description":"VR9030B - It was developed to integrate excitation systems of synchronous motors or generators. This type of application requires that the field be monitored to detect a first occurrence of ground fault, thus preventing a second fault at another point from damaging the system. The relay can detect ground fault even with the machine stopped and excitation turned off, not depending on the excitation voltage to detect the fault.\n\n• 110 VAC or 220 VAC power supply.\n• Can be applied in fields of up to 600 VDC.\n• Front Test/Trip Button.\n• Front Reset Button.\n• Remote “Test/Trip” dry contact input.\n• Remote “Reset” dry contact input.\n• NO/NC dry contact output\n• Delay time selection of 0.5 sec or 5 sec.\n• Status and actuation indication by LEDs.","files":[{"id":1347,"name":"Relé geral","ext":"pdf","link":"2023/4/20230411085046470","lang":"PT","role":"certificate"},{"id":15018,"name":"Catálogo Comercial","ext":"pdf","link":"2023/5/20230531121002606","lang":"PT","role":"catalog"},{"id":20567,"name":"terra site","ext":"png","link":"2024/8/20240812133155360","lang":"PT","role":"certificate"},{"id":26231,"name":"PT - Boletim Técnico - VR9030B Falta Terra","ext":"pdf","link":"2025/1/20250128161045308","lang":"PT","role":"manual"},{"id":26232,"name":"EN - Boletim Técnico - VR9030B Falta Terra","ext":"pdf","link":"2025/1/20250128161118587","lang":"EN","role":"manual"}],"shared":[],"categories":[{"id":13,"text":"Protection for Excitation Systems","sub":[]}],"properties":[{"property":{"id":1,"text":"Voltage","type":1,"pre":"","pos":""},"values":[{"id":145,"text":"Maximum: 600 VDC"}]},{"property":{"id":9,"text":"Power Supply","type":1,"pre":"","pos":""},"values":[{"id":99,"text":"110 VAC and 220 VAC"}]},{"property":{"id":39,"text":"Delay Time","type":1,"pre":"","pos":""},"values":[{"id":146,"text":"0.5 sec or 5 sec"}]}],"advantages":[],"sections":[{"text":"Discover the main features:","type":22,"nickname":"","desc":"","video":"","image":{},"cards":[],"link_text":""}]}
