Product Overview

ABB 2CDS281001R0377 is a single-pole miniature circuit breaker designed for protecting electrical circuits in low voltage applications. The product belongs to ABB System pro M compact series, which is widely used in professional electrical installations requiring compact dimensions and reliable protection performance.

The S201P-K6 model provides a rated current of 6 amperes and uses a K-type tripping characteristic. This makes the breaker suitable for circuits containing equipment with moderate starting currents, including industrial control devices, transformers, motors and automation components.

Unlike simple switching devices, miniature circuit breakers provide automatic protection by monitoring electrical current conditions. When an overload or short circuit occurs, the internal protection mechanism responds quickly to disconnect the circuit and reduce the risk of equipment damage.

The compact design of ABB 2CDS281001R0377 allows efficient installation inside electrical cabinets, distribution boards and industrial control panels. Its standardized mounting design supports convenient integration into modern electrical systems.

Main Functions and Features

The primary function of ABB 2CDS281001R0377 is circuit protection. The breaker continuously monitors current flow and disconnects the protected circuit when abnormal electrical conditions exceed predefined limits.

The K characteristic curve is an important feature of this model. Compared with standard characteristics, K curve breakers allow higher temporary current peaks while maintaining reliable protection. This makes them suitable for electrical loads that require additional starting current during operation.

The ABB S201P-K6 provides both overload protection and short-circuit protection. Overload protection prevents excessive continuous current from overheating cables and equipment, while short-circuit protection provides rapid disconnection during severe fault conditions.

The device is designed according to ABB’s professional electrical protection standards, providing stable mechanical operation and reliable electrical performance for industrial applications.
