  • INQUIRY

The Terasaki XS Series is one of its core, most widely used standard air circuit breakers. Renowned for high reliability, flexible configuration, and powerful protection features, it holds a dominant position, especially in industrial, building, and marine power systems.

Terasaki XS Series Core Features

• Application Fields: Widely used in main distribution boards, sub-distribution boards in factories, buildings, and infrastructure, as well as protection switches for large equipment like motors and transformers. It is a standard configuration in marine power systems.

• Technical Core: Commonly utilizes advanced solid-state electronic trip units, providing high-precision protection characteristics and adjustable parameters.

• Modular Design: Can be equipped with various functional modules (auxiliary contacts, shunt releases, undervoltage releases, etc.) to meet diverse control needs.

• High Breaking Capacity: Offers multiple models ranging from standard to very high breaking capacities, enabling the safe interruption of large short-circuit currents.

• Frame Ratings: Covers a medium current range. Common frame ratings include 100A, 250A, 400A, and 800A.
