In the context of miniature circuit breakers (MCBs), "C 32" refers to the type and rating of the breaker. The "C" indicates a type of tripping characteristic suitable for circuits with moderate inrush currents, typically used for inductive loads, while "32" denotes the current rating of the MCB, which is 32 amps. This means the MCB is designed to protect a circuit with a maximum load of 32 amps and can trip under overload or short-circuit conditions.

What is the full form of MCB?
The definition of MCB is a miniature circuit breaker, it trips if there is a line to natural fault. Ill add some extra information about the different types. RCD - residual current device = This is what you could separate you're circuits up with by inserting 1 of these in you're consumer unit (if you have lets say 10 circuits it goes like this... rcd-mcb-mcb-mcb-mcb-mcb-rcd-mcb-mcb-mcb-mcb-mcb-main switch. you see the rcd's control 5 circuits each, if 1 of these circuits had an earth fault on it, the rcd will trip and 5 of them circuits will go off, which means you have to keep tripping in you're rcd with an mcb 1 at a time to see which circuit the fault is on. RCBO - residual current breaker with overload protection- These can be installed in place of mcb's and rcd's, the rcbo is an mcb and rcd in 1 breaker. For example, i have installed a consumer unit full of these, in this case if a circuit forms a fault then its only that circuit that goes off. I hope this extra piece of information helps you along and best of luck. <<>> In electrical terminology MCB stands for Miniature Circuit Breaker.

MCB Bank Limited was created in 1947.
What is 130 degrees C in F degree?
Converting Celsius measurements to Fahrenheit measurements, you can use this formula: (9/5)C+32=F Meaning: 130 * (9/5) + 32 = 266 266 Degrees F To do the reverse, use this formula: F * (5/9) - 32 = C 266 * (5/9) - 32 = 130

What is mcb and cb?
MCB = Miniature Circit Breaker CB = Circuit Breaker
When will a 32 amp mcb trip?
The circuit protected by a 32 amp circuit breaker will trip when the circuit loading reaches on or about 32 amps. Theoretically a 32 amp breaker will not trip until current exceeds 32 amps. But this is affected by actual conditions such as ambient temperature, the integrity of the termination, the temperature of the breakers immediately adjacent to it, etc. In the United States the NEC requires that you not knowing load a breaker to greater than 80% of its rating. This avoids what is called nuisance tripping. Most common MCBs have an inverse-time component. This means the higher the current the faster it will trip. A current of 100 amps caused by a short circuit will trip faster than 33 amps which would most likely be an overload condition. The difference may not be noticeable without testing equipment.
