ABB Electrical S282UC-K16 Circuit Breaker

ABB Electrical S282UC-K16 Circuit Breaker

Basic Information

Meaning of model number: In ‘S282UC-K16’, S282 indicates the series to which the circuit breaker belongs, UC may represent its specific application scenario or design characteristics, K indicates that its tripping characteristic curve is of K-type, and 16 indicates that its rated current is 16A.

Electrical Parameters: Suitable for AC 50/60Hz circuits with a rated voltage of 400V, with a rated short-circuit breaking capacity of 10kA at 230V and 25kA at 400V, a rated insulation voltage of 500V, and a rated surge withstand voltage of 4kV.

Physical dimensions: width 0.035m, height 0.090m, depth 0.058m, net weight 0.281kg.

Functional features

Protection function: overload and short circuit protection. Through the principle of thermal magnetic release, the thermal release element can be used in overload, the heat generated by the current deforms and bends the bimetal, which pushes the release mechanism to act and cuts off the circuit; when a short circuit occurs, the electromagnetic release device responds quickly and generates a strong electromagnetic force, which causes the armature to close and drives the release mechanism to act, thus realising the protection against short circuits.

Withholding characteristics: K-type withholding characteristic curve, so that it can be better adapted to different types of loads and fault current characteristics, the response to the fault current is more accurate, effective protection of lines and equipment. For example, for some loads with large starting current but short duration, the K-type release characteristic can avoid false operation during starting, and at the same time quickly and reliably cut off the circuit in case of overload or short-circuit.

Installation: DIN rail mounting, this installation method is simple and convenient, can be quickly installed on the standard DIN rail, easy to be flexibly laid out and expanded in distribution cabinets and other electrical equipment, saving installation space and time, and improving installation efficiency.

Fields of application

Industrial field: It can be used in factories for the distribution protection of various electrical equipment, such as motors, transformers, distribution cabinets and other branch circuit protection, to prevent equipment damage and production interruption due to circuit failure, to ensure the continuity and stability of the production process.

Commercial places: It is suitable for the power distribution protection of lighting system, socket circuit, air-conditioning system, etc. in shopping malls, office buildings, hotels, etc., to ensure the reliability and safety of power supply, and to provide stable power support for commercial operations.

Data centre: The servers and network equipments in data centre require high stability of power supply, this circuit breaker can be used to protect the branch circuits of these key equipments, prevent data loss and equipment damage caused by electrical faults, and ensure the normal operation of the data centre.

The AC 800F is available in two versions:  

• 4 MB static RAM, 4 MB EPROM  

• 16 MB synchronous dynamic RAM,   8 MB EPROM

The AC 800F optionally provides several levels  of redundancy: 

• device redundancy with 2 AC 800F  

• power supply redundancy (24 V DC)  

• Ethernet communication redundancy   (standard)  

• Cable redundancy for Profibus DP,   requires external equipment (RLM01)

AC 800F Controller Redundancy

Controller redundancy can be achieved by installing two  AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated  redundancy communications link through the second Ethernet  module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant  operation.
