ABB 2CDS282001R0337 S202P-K4 Miniature Circuit Breaker

ABB 2CDS282001R0337 is the product identification number for the ABB S202P-K4 miniature circuit breaker. It belongs to the System pro M compact S200P family and is configured with two poles, a K tripping characteristic and a rated current of 4 A. The device is intended for circuit protection applications where reliable protection against overload and short-circuit conditions is required.

The S200P family combines compact modular construction with electrical protection functions suitable for residential, commercial and industrial distribution systems. The complete article number is important when identifying the correct device because the S200P family includes different pole configurations, current ratings and tripping characteristics. For this reason, 2CDS282001R0337 should be used as the primary identification reference when selecting or replacing this specific circuit breaker.

ABB 2CDS282001R0337 Product Overview

The ABB S202P-K4 is a two-pole miniature circuit breaker with a K characteristic and a 4 A rated current. Its product identification number is 2CDS282001R0337. The device is part of ABB’s S200P series of miniature circuit breakers and is designed as a modular protective component for low-voltage electrical distribution.

As an MCB, the S202P-K4 provides protection against abnormal current conditions. Its thermal protection mechanism responds to overload conditions, while its electromagnetic protection mechanism provides rapid response to short-circuit conditions. This combination allows the circuit breaker to provide a practical protection solution for circuits that require controlled overcurrent protection.

Technical Specifications

S202P-K4 K Tripping Characteristic

The K tripping characteristic is an important identification feature of ABB 2CDS282001R0337. S200P miniature circuit breakers are available with different tripping characteristics, and these characteristics affect the response of the protective device under increased current conditions.

The K characteristic makes the S202P-K4 distinct from other 4 A variants in the ABB S200P product family. When selecting a replacement, the complete designation should therefore be checked rather than relying only on the rated current. A circuit breaker with the same current rating but a different characteristic may not provide the same electrical behavior as the specified S202P-K4.

Two-Pole Circuit Protection

ABB 2CDS282001R0337 uses a two-pole configuration, with both poles protected. The compact modular format allows the device to be integrated into distribution boards and control panels where space and organized circuit protection are important.

The two-pole configuration is useful for electrical circuits where two conductors need to be controlled through a common protective device. The precise wiring arrangement should always follow the applicable electrical design, installation requirements and ABB documentation for the equipment in which the breaker is installed.

System pro M compact S200P Series

The S202P-K4 is part of ABB’s System pro M compact S200P miniature circuit breaker family. The product family contains multiple configurations covering different rated currents, pole counts and tripping characteristics.

Within this product range, the article number provides a precise method of identifying the required configuration. For example, the ABB product catalog associates 2CDS282001R0337 specifically with S202P-K4, while nearby article numbers correspond to other current ratings. This makes the complete product ID particularly useful for procurement, maintenance and replacement work.

Circuit Protection Applications

ABB 2CDS282001R0337 can be used as a modular protective component in electrical distribution and control installations. Typical application environments for S200P miniature circuit breakers include distribution boards, control cabinets, industrial electrical systems, commercial installations and other low-voltage circuits requiring overcurrent protection.

The device is designed to protect electrical circuits from overload and short-circuit conditions. In a properly engineered installation, the selected breaker rating and tripping characteristic are matched to the protected circuit, conductor capacity and system requirements.

DIN Rail Installation

The S202P-K4 uses a compact modular construction suitable for DIN rail mounting. Its approximately 35 mm overall width corresponds to a two-module configuration, allowing it to be arranged alongside other modular electrical components in a distribution or control cabinet.

The compact dimensions also simplify equipment layout where multiple protection devices must be installed within a limited panel space. Before installation, the mounting rail, conductor arrangement, accessory requirements and electrical clearances should be checked against the applicable installation standards.

Identification and Replacement

When identifying an ABB miniature circuit breaker, the visible product designation and complete order number should be considered together. For this product, the important references are S202P-K4 and 2CDS282001R0337.

Using only the description “ABB 4 A circuit breaker” is not sufficient for precise replacement because the S200P family contains multiple 4 A configurations and different tripping characteristics. The complete ABB product ID provides a more accurate reference for purchasing, maintenance records and equipment documentation.

ABB 2CDS282001R0337 Selection Considerations

Before selecting ABB 2CDS282001R0337 for an electrical installation, engineers should verify the required rated current, number of poles, tripping characteristic, operating voltage, short-circuit level and applicable installation standards. These parameters determine whether the specific circuit breaker is suitable for the intended circuit.

Particular attention should be given to the K characteristic and the 4 A rated current. If a replacement is required, the original circuit design and protective coordination should be reviewed before substituting another breaker with a different characteristic or rating.

ABB 2CDS282001R0337 Product Summary

ABB 2CDS282001R0337, identified as S202P-K4, is a two-pole miniature circuit breaker in the ABB System pro M compact S200P family. It has a K tripping characteristic, 4 A rated current, 400 V AC rated operational voltage and a 25 kA short-circuit capacity according to the applicable product specifications.

Its modular DIN rail format makes it suitable for integration into electrical distribution and control equipment. For purchasing, maintenance and technical identification, the complete product number 2CDS282001R0337 should be retained together with the S202P-K4 type designation to ensure that the correct ABB configuration is identified.
