A TPN MCCB is a three phase neutral molded case circuit breaker. This type of circuit breaker is commonly used in low voltage power distribution systems.
VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.

MCB (Miniature Circuit Breaker)-rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation. Breakers illustrated above are in this category.MCCB (Molded Case Circuit Breaker)-rated current up to 2500 A. Thermal or thermal-magnetic operation. Trip current may be adjustable in larger ratings.

AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
An SPN MCCB is a Solid Pole Neutral Molded Case Circuit Breaker.

Yes. The circuit breaker "does not care" which direction the current comes from. It is capable of protecting the circuit in any case.
VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.
Circuit breakers do not have circuit diagrams. The breakers have an input where the distribution voltage is applied and an output where the load is applied. If you want to know what is inside a breaker, the electrical terminology to use is "shop drawings" of the specific breaker that you need information on.
To trip a circuit breaker in case of an electrical overload, locate the circuit breaker panel in your home, identify the breaker that corresponds to the overloaded circuit, and switch it to the "off" position. This will cut off power to the circuit and prevent further damage.
Ir is the Interrupt rating of the circuit breaker. It is the maximum amount of current the breaker can withstand without damage. In a molded case breaker's electronic trip mechanism, Ir is the continuous current rating that you select, to trip the breaker at a given overload current. Standard requirements request that the breaker trips at 2 hours with an overload of 135% and will trip as a function of I squared x time selected for higher currents.
A common type of circuit breaker used in a load center is a miniature circuit breaker (MCB) or a molded case circuit breaker (MCCB). These circuit breakers protect the electrical system from overload and short circuits by interrupting the flow of current when necessary. They come in various sizes and ratings to suit different applications within the load center.
