An electrical issue caused by an overload or a short circuit is referred to as a short circuit. We used to defend against over-current with fuse wire (in fact, we used to sell it!) back in the day. The concept was simple: an over-current would physically “blow” the fuse wire by quickly heating and melting it. MCBs expand on this functionality by not being destroyed during an over-current and so being reusable. It’s also considerably easier to use, with the simplicity of ‘on or off switching’ for the circuit isolation. They are much safer to use and operate because the conductor is then housed within some plastic shell. It’s worth noting that MCBs don’t protect people against electrical shock generated by ‘earth leakage.’ RCDs and the RCBOs are the devices that perform this service. Kilo Amperes, Amperes, and Tripping Curve are the three main features of an MCB. Overload Current Ratings – Amperes (A) When too many appliances are connected to a single circuit, they use more electrical current than the circuit and cable were designed to handle. It may happen in the kitchen if the kettle, dishwasher, electric range, microwave, and blender are used simultaneously. The MCB on this circuit cuts electricity, keeping the cable and terminals from overheating and catching fire. Kilo Amperes – Short Circuit Rating (kA) Short circuits are caused by a failure in an electrical circuit or appliance, and they can be even more harmful […]<\/p>\n","protected":false},"author":1,"featured_media":597,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[49],"tags":[],"class_list":["post-596","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"yoast_head":"\n
