In the realm of low-voltage power distribution and motor control, the XT3 series represents a pinnacle of molded case circuit breaker (MCCB) engineering. These devices are designed for robust protection of electrical circuits against overloads and short circuits, typically rated for currents from 250A up to 630A, with a breaking capacity that can reach 100kA at 415V AC. The XT3 breakers are available in 3-pole (3P) and 4-pole (4P) configurations, supporting fixed or plug-in mounting options. They feature electronic trip units with adjustable settings for long-time delay, short-time delay, instantaneous, and ground fault protection, ensuring precise coordination in complex industrial networks. The compact design and high performance make them ideal for main switchboards, distribution panels, and critical motor control centers.
These circuit breakers are extensively deployed in heavy industries such as manufacturing plants, oil and gas facilities, data centers, and commercial buildings where high fault currents are a concern. They are also used in renewable energy systems, including solar photovoltaic arrays and wind turbine installations, to protect inverters and transformers. The XT3 series is particularly suited for environments requiring high reliability and selectivity, such as hospitals and airports, where uninterrupted power supply is critical. Their ability to withstand harsh conditions, with an IP20 protection rating for the front panel, ensures safe operation in dusty or humid industrial settings.
The XT3 category encompasses several subcategories and key article codes that define its versatility. The main product codes follow a structured format: XT3 followed by a numeric suffix indicating the frame size and trip unit type. For example, XT3-250 indicates a 250A frame, while XT3-630 denotes the 630A variant. Subcategories include fixed versions (e.g., XT3-250-F), plug-in versions (e.g., XT3-250-P), and electronic trip units (e.g., XT3-250-E). Accessories like rotary handles, shunt trips, and auxiliary contacts are also available, but the core articles focus on the breakers themselves. These codes are standardized across global markets, ensuring easy identification and compatibility.
