ABB Electrical 2CSF204001R1250 Residual Current Circuit Breaker

Basic Parameters

Rated Voltage: Usually applicable to 240V voltage level circuits, can work stably under this voltage, effectively protect electrical equipment and personal safety.

Rated current: 25A, capable of carrying and protecting electrical equipment below the rated current, can meet the protection needs of general households, offices and small commercial premises and other electrical equipment.

Number of poles: 4 poles, suitable for three-phase four-wire power supply system, can simultaneously monitor and protect the three-phase fire wire and neutral wire leakage, to ensure that the system leakage protection function is more comprehensive and reliable.

Rated leakage action current: 30mA, with high leakage protection sensitivity, can quickly detect and cut off the circuit in the event of a slight leakage, effectively preventing electrocution accidents, to protect personal safety, especially for personal electric shock protection requirements of strict places, such as residential, schools, hospitals, etc..

Short-circuit breaking capacity: its short-circuit breaking capacity to meet the general electrical system short-circuit protection requirements, when a short-circuit fault occurs in the circuit, the circuit can be cut off in a timely manner, to limit the fault current on the lines and equipment damage to ensure the safe operation of the electrical system, but the specific short-circuit breaking capacity values need to refer to the product details of the technical manual.

Impact withstand voltage: with a certain impact withstand voltage capability, can appear in the power grid transient overvoltage, such as lightning impact, etc., can still work normally, to protect the stability of the equipment and system, but the specific impact withstand voltage values need to refer to the product technical data.

Performance characteristics

Leakage protection: real-time monitoring of the residual current in the circuit through the zero sequence current transformer, when the residual current reaches or exceeds the rated leakage action current, it will quickly trigger the release mechanism to cut off the circuit, thus effectively preventing electric shock accidents and electrical fires and other safety hazards caused by leakage.

A-type earth leakage protection: A-type earth leakage circuit breaker can not only detect AC residual current, but also detect pulsating DC residual current, and effectively detect and protect DC component leakage faults generated by electronic equipment, etc., which enlarges the scope of protection and improves the reliability of protection, and it is suitable for the electrical system containing a large number of electronic equipment.

High breaking capacity: In the event of a short-circuit fault, it can quickly and reliably cut off the short-circuit current, and its short-circuit breaking capacity ensures that when the short-circuit current is large, it can also effectively protect the lines and equipment, reduce the losses caused by short-circuit faults, and safeguard the stability and reliability of the electrical system.

Environmental adaptability: the working temperature range is wide, generally can be - 25 ℃ to 55 ℃ of the ambient temperature of normal operation, can be adapted to different seasons and environmental conditions of the electrical installation places, such as indoor and outdoor distribution boxes, distribution cabinets and so on. In addition, its protection class is IP2X, which can effectively prevent the intrusion of foreign objects and adapt to certain dust and foreign object protection requirements.

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

Selective protection: 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 each level of earth leakage circuit breaker, 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, to reduce the scope of the power outage, and to improve the reliability and continuity of power supply.

Application areas

Residential: as an important protection appliance in residential power distribution box, it can provide leakage protection for sockets, lighting fixtures, household appliances, etc. in the family, effectively preventing personal electric shock accidents caused by leakage of electrical appliances, and safeguarding the safety of residents and the reliability of household electricity.

Commercial places: Widely used in shopping malls, office buildings, hotels and other commercial buildings in the electrical system, used to protect lighting circuits, socket circuits, air-conditioning systems, lifts and other electrical equipment, to prevent electrical fires caused by leakage faults, to protect the safety of the electrical facilities and property of the commercial building.

Industrial field: In all kinds of industrial plants and workshops, it can be used to protect electric motors, processing equipment, lighting systems and other electrical equipment in production lines, preventing safety accidents caused by equipment leakage and short-circuit faults, guaranteeing normal industrial production, and improving the service life and operational efficiency of production equipment.

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 safe and comfortable environment for public activities.
