Technical Specifications

Information About S144A

The S144A is a molded case circuit breaker (MCCB) from Schneider Electric, categorized under the POWERPACT series. It is engineered for reliable protection of electrical circuits and equipment in industrial and commercial environments. This device provides protection against overloads, short circuits, and ground faults, ensuring the electrical system operates within safe parameters. Designed for versatility and ease of integration, the S144A incorporates advanced features to meet modern electrical protection demands, including enhanced monitoring and trip capabilities.

Trip Unit and Protection
The S144A is equipped with a MICROLOGIC 6.0 trip unit, which offers advanced protection and control functionality. The MICROLOGIC 6.0 is designed for precise detection of electrical faults, allowing for timely interruption of the circuit in case of abnormal conditions. This trip unit offers LSIG (Long Time, Short Time, Instantaneous, Ground Fault) protection, covering a broad spectrum of electrical fault conditions. LSIG protection ensures that the circuit breaker responds appropriately to both gradual overload conditions and sudden, severe faults such as short circuits or ground faults.

Frame Type
The S144A is available in two frame types: P-FRAME and R-FRAME. These frames define the structural design and capacity of the circuit breaker, supporting different ranges of current ratings and operational requirements. The P-FRAME is typically used for medium to high current applications, while the R-FRAME is suited for heavier industrial operations with higher current capacities. This flexibility in frame types allows the S144A to be deployed in a range of installations, from smaller commercial setups to large-scale industrial environments.

Rating Plug
The inclusion of a rating plug in the S144A enables easy adjustment of the circuit breaker’s current rating. This feature allows for adaptability in various electrical systems by providing the ability to set the trip current according to the specific load and protection requirements of the installation. The rating plug ensures that the circuit breaker can be fine-tuned for optimal performance without the need for replacing the entire unit when current specifications change. This modularity enhances the usability and longevity of the S144A in dynamic electrical environments.
