Electrical 2CSF204101R1250 Residual Current Circuit Breaker

ABB Electrical 2CSF204101R1250 Residual Current Circuit Breaker

Basic Parameters

Rated voltage: 400V, suitable for common low-voltage distribution system, can work stably under this voltage level, provide effective leakage protection for electrical equipment.

Rated current: 25A, can meet the normal operation and protection needs of electrical equipment within a certain power range, such as for the protection of some small and medium power motors, lighting equipment and other branch circuit.

Number of poles: 4 poles, suitable for three-phase four-wire system or three-phase five-wire power supply system including neutral wire, can simultaneously monitor and protect the three-phase fire wire and neutral wire for earth leakage, to ensure the safety and reliability of the system.

Rated leakage action current: 30mA, this sensitivity can be quickly detected and cut off the circuit when a slight leakage occurs, effective protection of personal safety, to prevent electrocution accidents, especially suitable for personal electric shock protection of higher requirements of the place, such as residential, office and so on.

Short-circuit breaking capacity: 1kA, when a short-circuit fault occurs in the circuit, it can reliably cut off the circuit when the short-circuit current reaches 1kA, and protect the electrical equipment and lines from the damage of short-circuit current.

Impact withstand voltage: 4kV, with high impact withstand voltage capacity, can appear in the power grid transient overvoltage, such as lightning impact, etc., can still work normally, to protect the stability of equipment and systems.

Performance characteristics

Leakage protection function: by detecting the residual current in the circuit to determine whether a leakage fault occurs. Under normal circumstances, the three-phase current vector sum in the circuit is zero, zero-sequence current transformer has no induced electromotive force. When leakage occurs, such as human electric shock or equipment insulation damage caused by current leakage, the three-phase current vector sum is no longer zero, the zero sequence current transformer generates inductive electromotive force, triggering the action of the release device, quickly cut off the circuit, thereby protecting personal safety and preventing electrical fires and other accidents.

A variety of leakage current type detection: A type leakage circuit breaker, not only can detect AC residual current, but also can detect pulsating DC residual current, containing electronic equipment such as DC component leakage faults can also be effectively detected and protected, expanding the scope of protection, improve the reliability of protection.

High breaking capacity: short-circuit breaking capacity of 1kA, in the event of a short-circuit fault, can quickly cut off the short-circuit current, limiting the extent of damage to the fault current on the lines and equipment, to ensure the stability and safety of the electrical system, reduce the short-circuit faults triggered by the outage time and the cost of equipment maintenance.

Good environmental adaptability: the working temperature range is - 25℃ to 55℃, it can work normally in a wide temperature range, and adapt to different environmental conditions of the electrical installation places, such as indoor and outdoor distribution boxes, distribution cabinets and so on. In addition, its protection class IP2X can effectively prevent the intrusion of foreign objects, and adapt to certain dust and foreign object protection requirements.

Compact Design and Convenient Installation: DIN rail mounting is adopted, which is convenient and quick to install, saves installation space and time, and facilitates the layout and maintenance in the distribution cabinet or distribution box. Its small external dimensions and compact structure make it suitable for installation in electrical control boxes with limited space.

Selective protection function: It has selective protection function, which can be set according to the actual application requirements. In the multi-level earth leakage protection system, through the reasonable setting of the action time and action current of all levels of earth leakage circuit breakers, to achieve selective cooperation between the upper and lower levels, to ensure that in the event of an earth leakage fault, only the leakage circuit breaker closest to the point of the fault operates, reducing the scope of the blackout, and improving the reliability and continuity of the power supply.

Application field

Industrial field: Widely used in all kinds of industrial plants and workshops for the protection of electrical equipment, such as electric motors on production lines, processing equipment, lighting systems and so on. It can effectively prevent the safety accidents caused by equipment leakage, short-circuit and other faults, ensure the normal progress of industrial production, and improve the service life and operational efficiency of production equipment.

Commercial buildings: In shopping malls, office buildings, hotels and other commercial buildings, it is used to protect lighting circuits, socket circuits, air-conditioning systems, lifts and other electrical equipment. Provide a safe environment for personnel to use electricity, and at the same time to avoid electrical fires caused by leakage faults, to protect the electrical facilities of commercial buildings and property safety.

Residential buildings: It is one of the important protection appliances in the residential distribution box, providing leakage protection for household electrical equipment, such as sockets, lighting fixtures, household appliances and so on. It can effectively prevent personal electric shock accidents caused by leakage of electrical appliances, and protect the life safety of residents and the reliability of home electricity.

Public facilities: including schools, hospitals, gymnasiums, libraries and other public facilities in the electrical system, for the protection of various types of electrical equipment and lighting facilities, to ensure the safety of electricity in public places, to provide people with a safe and comfortable environment for public activities.
