It provides non-invasive current sensing with a 15A rated current and 12.5 mV output voltage. The through-hole mounted transformer features a 6.0mm inner diameter for conductor routing, making it ideal for residual current circuit breakers (RCCB), earth leakage detectors, and smart metering applications.","working_principle":"The MR\/C-01 operates as a zero-phase current transformer. When a conductor carrying AC current passes through the center aperture, the transformer detects the vector sum of all currents (phase and neutral). Under normal conditions, the vector sum is near zero. When a ground fault occurs, the imbalance creates a net magnetic flux that induces a voltage in the secondary winding proportional to the leakage current. The 12.5 mV output at rated current provides a measurable signal for downstream detection circuitry.","pin_description":"<table>\n<tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr>\n<tr><td>1<\/td><td>Secondary+<\/td><td>Output<\/td><td>Secondary winding output - connect to detection circuit<\/td><\/tr>\n<tr><td>2<\/td><td>Secondary-<\/td><td>Output<\/td><td>Secondary winding return - connect to detection circuit<\/td><\/tr>\n<tr><td>-<\/td><td>Primary Aperture<\/td><td>Passive<\/td><td>6mm opening for primary conductor routing<\/td><\/tr>\n<\/table>","application_scenarios":"<ul>\n<li>Residual current circuit breakers (RCCB\/RCD) for electrical safety<\/li>\n<li>Earth leakage current monitoring in industrial installations<\/li>\n<li>Smart metering and energy management systems<\/li>\n<li>Building management and fire prevention systems<\/li>\n<li>EV charging station safety monitoring<\/li>\n<\/ul>","alternative_models":"<table>\n<tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Notes<\/th><\/tr>\n<tr><td>KEMET<\/td><td>MR\/A-01<\/td><td>Alternative ZCT variant<\/td><\/tr>\n<tr><td>KEMET<\/td><td>C\/CT-01<\/td><td>Current transformer variant<\/td><\/tr>\n<tr><td>Murata<\/td><td>5600C<\/td><td>Current sense transformer<\/td><\/tr>\n<tr><td>Pulse<\/td><td>PE-51657<\/td><td>Residual current transformer<\/td><\/tr>\n<\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10897","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/comments?post=10897"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/posts\/10897\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/media?parent=10897"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/categories?post=10897"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/tags?post=10897"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=10897"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
