UPGF6-30513-3 Application Field and Working Principle

UPGF6-30513-3 circuit breaker is one of the commonly used products in the field of circuit breakers. It mainly applies to industrial control, information distribution systems, electric power generation and power grid operation. This product has the advantages of reliable performance, good technical performance, strong protection capability, complete product specifications, and can meet customer needs. Let’s have a look at UPGF6-30513-3 application field and working principle.

Application Field

The UPGF6-30513-3 circuit breaker mainly applies to the AC 50/60Hz, rated voltage 380V/400V/660V, rated current to 630A, and used in non-frequent operation of long line or intensive line protection occasions, such as industry, mines, chemical plants, farm and other occasions, which can be used for efficient short-circuit, overload, and leakage protection as well as long-term safe power supply.

The UPGF6-30513-3 circuit breaker uses a anti-pumping device, suitable for life-building, computer room, communication room, engineering, etc., with complete specifications and excellent performance, demonstrating its superior application field.

Working Principle

The UPGF6 circuit breaker is equipped with a single-phase automatic tripping device, double-phase reversing trip device and double break main contact system, uses special oil-immerging arc extinguishing technology and complex machine type, product structure is reasonable, protection performance is strong, reliable and with long product life.

The current-carrying connection ring or contact plate is connected with the mains and the load of the protected circuit. When the circuit has a short-circuit fault, it is equivalent to a small resistance connected in series in the current circuit of the working circuit. The current in the circuit will increase and exceed the set value of the circuit breaker. Then the circuit breaker will promptly cut off the fault circuit and protect the equipment of theprotected circuit.

At the same time, the circuit breaker is also equipped with an overload protection device. When the current is higher than the set value of the overload protection device, the trip device will be activated and the circuit breaker will act to cut off the fault current by tripping.

UPGF6-30513-3 circuit breaker has its own functions in many fields, and it adopts the safety designs of current limiting and power limiting. Its characteristics and performance are excellent, and it is very worth having for the majority of users.
