ABB Electrical S202-C16 400V AC Circuit Breaker

ABB Electrical S202-C16 400V AC Circuit Breaker

Basic Parameters

Rated voltage: 400V AC, suitable for AC circuits of this voltage level, can provide corresponding protection for electrical equipment and lines.

Rated current: 16A, in this current and below, the circuit breaker can work normally, when the current exceeds 16A, the circuit breaker will cut off the circuit according to the overload or short-circuit situation.

Number of poles: 2 poles, mainly used for controlling and protecting single-phase or two-phase AC circuits, suitable for household, commercial and some industrial electrical equipment and circuits, such as lighting circuits, socket circuits and so on.

Functional characteristics

Protection function:

Overload protection: realised by the internal thermal release element. When the current in the circuit exceeds the rated current of 16A for a long time, the bimetal in the thermal release element will be bent and deformed due to heat, which will push the release mechanism to act, thus cutting off the circuit and effectively preventing the lines and equipment from being damaged due to overload.

Short-circuit protection: once a short-circuit fault occurs in the circuit, the instantaneous generation of a huge short-circuit current will make the electromagnetic detacher act quickly, generating a strong electromagnetic force to attract the armature, drive the detacher mechanism, quickly cut off the circuit, limit the impact of the fault in the smallest possible range, to protect the equipment and personnel safety.

Withholding characteristics: C-type withholding characteristic curve, its instantaneous withholding current is 5-10 times the rated current, i.e., between 80A-160A, which can better adapt to the general characteristics of civil and commercial loads, effectively avoiding the damage caused by overload or short-circuit on the equipment.

Installation: DIN rail mounting, this way is simple and convenient, can be easily mounted on the standard DIN rail, in the distribution cabinet and other electrical equipment for flexible layout, saving installation space and time, improve installation efficiency.

Application Areas

Industrial field: It can be used for the distribution protection of various small electrical equipment in factories, such as small motors, control circuits, lighting systems and other branch circuit protection, to ensure the stable operation of electrical equipment in the production process, to prevent the interruption of production due to circuit failure.

Commercial places: It is suitable for the protection of lighting circuits and socket circuits in shopping malls, office buildings, hotels, etc., to ensure the reliability and safety of power supply, provide stable power support for commercial operations, and avoid the normal development of commercial activities due to electrical failures.

Residential: In the family electricity, it can protect all kinds of electrical equipment and lighting circuits, prevent overload or short circuit from causing electrical fires and other safety accidents, ensure the safety of residents' electricity consumption, and provide reliable protection for the family electricity consumption.

OTHER INFORMATION

• Read the safety precautions carefully. 

• Check the delivery for transportation damage. If damage is found, notify the  supplier as soon as possible. 

• Do not use the operator panel in an environment with high explosive hazards. 

• The supplier is not responsible for modified, altered or reconstructed  equipment. 

• Use only parts and accessories manufactured according to specifications of the  supplier. 

• Read the installation and operating instructions carefully before installing,  using or repairing the operator panel. 

• Never allow fluids, metal filings or wiring debris to enter any openings in the  operator panel. This may cause fire or electrical shock. 

• Only qualified personnel may operate the operator panel. 

• Storing the operator panel where the temperature is lower/higher than  recommended in this manual can cause the LCD display liquid to  congeal/become isotopic. 

• The LCD display liquid contains a powerful irritant. In case of skin contact,  wash immediately with plenty of water. In case of eye contact, hold the eye  open, flush with plenty of water and get medical attention.
