In the world of low-voltage power distribution and motor control, the XT1 series represents a compact yet robust family of molded case circuit breakers (MCCBs) designed for high-performance protection. These devices typically feature a rated operational voltage up to 690V AC, with current ratings ranging from 16A to 160A, and a breaking capacity that can reach up to 36kA at 415V AC depending on the specific variant. The XT1 is available in 3-pole (3P) and 4-pole (4P) configurations, supporting both fixed and plug-in mounting options. Key technical attributes include thermal-magnetic or electronic trip units, adjustable overload and short-circuit protection settings, and compatibility with a wide range of accessories such as shunt trips, undervoltage releases, and auxiliary contacts. The series is also known for its compact dimensions, making it ideal for space-constrained installations in switchboards and distribution panels.
The XT1 circuit breakers are extensively used in industrial automation, commercial buildings, and infrastructure projects. Common applications include main and branch circuit protection in distribution boards, motor protection in control panels, and protection of transformers, capacitors, and lighting circuits. They are particularly suited for environments requiring high reliability and selectivity, such as data centers, manufacturing plants, and renewable energy systems like solar inverters and wind turbine converters. The series also supports communication modules for integration into smart grid and building management systems.
Within the XT1 category, key subcategories include the XT1B (basic version with thermal-magnetic trip), XT1N (standard breaking capacity), and XT1S (high breaking capacity). Article codes typically follow a pattern like XT1B160 TMD (160A, thermal-magnetic), XT1N100 TMD (100A, standard breaking), or XT1S125 TMD (125A, high breaking). The code structure often includes the series prefix (XT1), followed by the breaking capacity variant (B, N, S), current rating, and trip unit type (TMD for thermal-magnetic, E for electronic). For example, XT1B160 TMD 3P denotes a 160A, 3-pole, thermal-magnetic breaker with basic breaking capacity.
