K2CM-2LS is a protection relay and system used for the protection of motor drives and other high-voltage loads. The K2CM-2LS system includes two relays, the K2CM-2L and the K2CM-2S. Both of these relays are designed to detect, sense, and protect against over-current conditions within motor drives and other high-voltage loads. The system is designed for monitoring and controlling loads that are protected by automatic overload relays or circuit breakers. The K2CM-2LS is designed for use in environments where combustible dust is present.

The working principle of the K2CM series is based on the principle of two-element protection. The primary element of the K2CM-2LS protection system is theK2CM-2L (low voltage) relay installation. This relay contains two electronic components, an alarm module and a trip module. The alarm module is designed to detect and accurately measure an over-current condition. The trip module will then actuate the trip circuit, which will disconnect the load from the supply if the over-current conditions persists for a predetermined period of time.

The secondary element of the K2CM-2LS protection system is the K2CM-2S (high voltage) relay installation. This relay contains two electronic components, a trip module and an alarm module. The trip module is designed to detect and accurately measure an over-current condition and actuate the trip circuit when the prospective fault current exceeds the set limit. The alarm module is designed to relay an alarm signal if the alarm level is exceeded for a predetermined period of time.

The K2CM-2LS protection system also has a number of additional features. It has an adjustable time delay function to prevent nuisance trips in the event of short-term overloads, as well as a "self-test" feature which allows the protective relays to be tested on a regular basis to ensure they are functioning correctly. It can also be connected to a remote monitoring system, allowing for remote monitoring and control of the protective relays.

The K2CM-2LS is suitable for use in industries ranging from power generation and distribution to manufacturing and mining. It is designed to provide accurate and reliable protection for high-voltage loads and motor drives, and is a suitable choice for applications in hazardous locations. In addition to providing over-current protection, the K2CM-2LS also provides accurate overload measurements and can monitor up to 4 loads at a time. This system is also suitable for use in hazardous locations and is designed to be fault tolerant in the event of a single relay failure.

In conclusion, the K2CM-2LS is an advanced protection relay and system designed for use in hazardous environments. Its two-element protection system provides accurate and reliable protection for high-voltage loads and motor drives. The system also features a number of additional features, such as adjustable time delay, remote monitoring, and self-test. The K2CM-2LS is suitable for use in a variety of industries, ranging from power generation and distribution to manufacturing and mining.
