When you need a reliable and compact solution for protecting electrical circuits against overloads and short circuits, the T4 series of molded case circuit breakers (MCCBs) stands out. These devices are designed for fixed or plug-in mounting, typically available in 3-pole (3P) or 4-pole (4P) configurations, with rated currents ranging from 16 A to 250 A. They offer breaking capacities up to 36 kA at 415 V AC, making them suitable for a wide range of industrial and commercial applications. The T4 series is known for its robust construction, thermal-magnetic or electronic trip units, and compatibility with a full range of accessories like shunt trips, undervoltage releases, and auxiliary contacts.
These circuit breakers are primarily used in low-voltage distribution boards, motor control centers, and main switchboards in industrial plants, commercial buildings, and infrastructure projects. They are ideal for protecting feeders, motors, transformers, and other critical equipment in environments where space is limited but reliability is paramount. The T4 series is also commonly found in renewable energy systems, such as solar photovoltaic installations, where they provide overcurrent protection for inverters and combiner boxes.
The T4 category includes several subcategories and key article codes, such as the T4N (standard breaking capacity), T4S (high breaking capacity), and T4L (very high breaking capacity). Typical article codes follow a pattern like T4N250, T4S160, or T4L100, where the number indicates the rated current in amperes. For example, T4N250 refers to a T4N frame with 250 A rating. Other variants include T4V (with electronic trip unit) and T4B (with plug-in base). These codes are essential for identifying the exact breaker configuration needed for your project.
