This advanced system includes B-type and C-type MCBs along with an HRC fuse, making it ideal for practical learning and testing applications.<\/p>\n<p>These protective devices are capable of carrying current under normal operating conditions and automatically interrupt the circuit during overload or short-circuit conditions. The system provides comprehensive learning content to help users understand the internal working and performance of MCBs and HRC fuses.<\/p>\n<p>The MCBs are housed in transparent enclosures, allowing visualization of internal components during testing. Two precise IC-based thermometers are mounted on the bimetal contacts to analyze temperature rise and fall. A digital timer with start and stop functionality enables the study of current versus tripping time characteristics.<\/p>\n<p>An inbuilt isolated variable AC power supply ensures safe operation. This system allows users to understand the differences between various classes of MCBs through practical experimentation.<\/p>\n<p>The Nvis 7090 serves as an ideal platform for enhancing education, training, and skill development in electrical protection systems.<\/p>\n<h2>Product Features<\/h2>\n<ul>\n<li>\u00a0Alphanumeric 16X2 Big Font LCD for better visibility<\/li>\n<li>\u00a0Isolated Power Supply using Transformer<\/li>\n<li>\u00a0Inbuilt variable current injection facility<\/li>\n<li>\u00a0Transparent MCB`s to understand internal architecture and its working<\/li>\n<li>\u00a0Inbuilt Timer, Current &amp; Temperature on LCD<\/li>\n<li>\u00a0MCBs are mounted with temperature sensor for current temperature analysis<\/li>\n<li>\u00a0Equipped with supply indication lamp<\/li>\n<li>\u00a0Designed by considering all the safety standards<\/li>\n<li>\u00a0Diagrammatic representation for the ease of connections<\/li>\n<li>\u00a0Learning material CD<\/li>\n<\/ul>\n<h6>Scope of Learning<\/h6>\n<div class=\"tech_specs\">\n<ul>\n<li>Study the operating characteristics of Miniature Circuit Breaker B-type 6A.
