Introduction The Safety is major concern when selecting the perfect electrical equipment, appliances, or devices for a property. Every piece of appliance we use in building the property of homes, offices, and industries needs a well-established electronic system that can prevent vulnerable damages like high inrush currents, power fluctuations, and short circuits. To avoid such power fluctuations in an electronic device, it is essential to incorporate safe and secured equipment in properties. A fuse is a conventional electronic device that is mostly used in the early days to protect the circuit. These days the fuse has been replaced by a more efficient and durable Siemens electronic device, known as MCB – Miniature Circuit Breaker. What is MCB A Miniature Circuit Breaker is efficient switchgear, available in the range of 0.5A to 100 Ampere capacity. Where a domestic MCB would normally have a 6kA fault level capacity, a 10kA fault capacitated MCBS with 415v and l...
