Difference Between Control Circuit And Power Circuit

The main contacts of a breaker are used to interrupt the flow of the current hence the power rating of these contacts will be high.

Difference between control circuit and power circuit. I e in a starters dol or star delta we use contactor when the contactor holds the power goes to the load. A power circuit provides significant electrical capacity to operate something that does a lot of work for example high power heaters or multi horsepower motors. Power circuits on the other hand carry high power as it is the main functioning circuit where the actual machine carries out the tasks. Relay is also used as a protective device which sense the fault signal and sends to the circuit breaker which make decision to make or break the circuit based on the provided information by the relay.

The main contacts have a fixed part a moving part and there is an arc extingushing medium between the two parts which extinguishes the arc during opening of the poles. Floor areas of no more than 50m2 requires a 20 a fuse or miniature circuit breaker protection with 2 5 mm live and 1 5mm protective conductors or 1 5 mm if m i. Here control circuit means the auxiliary circuit which is made with contactors no nc switches protecting relays mcb etc. A radial circuit must follow these rules in general.

Circuit latching is a way to control circuits in electricity. Battery the battery should be at least 75 charged to provide necessary voltage and current for the accurate starter operation. That s one reason every electrically powered item must be protected by a circuit breaker. Power circuit the purpose and function of power circuit is to create necessary power and transfer it from the battery to the starter motor which rotates the engine.

Main differences between circuit breaker and relay. The circuit breaker panel is an electrical protecting safety device. Whether it be a home fighter jet utility helicopter cargo airplane archangel etc. A power panel controls the electrical power for each panel and component in the aircraft.

Control supply is nothing but a separate power supply to operate or control the power circuits using control circuit. There is a load or loads that consume x watts of power to perform a function. When the latch is open all circuits have electrical current and when closed there will be no current. The main difference between the relay and the circuit breaker is that relay is a device that provides the signal to the circuit breaker in case of any fault in the power system whereas circuit breaker is the device that breaks the signal after receiving the message from the relay.
