Molded case circuit breakers (MCCBs) of the Isomax-Tmax series represent a benchmark in low-voltage power distribution and protection. These devices are engineered to deliver exceptional performance in a compact footprint, offering significant space savings in electrical panels and switchgear. The Tmax range is designed for ease of installation and integration, providing operators with unmatched reliability and safety. Available in various frame sizes, these breakers cover a wide spectrum of nominal currents from 1A to 3200A, with configurations including three-pole (3P) and four-pole (4P) versions. Key technical parameters include high breaking capacities (Icu/Ics) suitable for industrial applications, adjustable thermal-magnetic or electronic trip units for precise protection coordination, and compliance with international standards like IEC 60947-2. The modular design allows for straightforward addition of accessories such as shunt trips, undervoltage releases, and auxiliary contacts, enhancing their versatility in complex automation schemes.
These MCCBs are ideally suited for integration into secondary distribution systems for both AC and DC circuits. Their primary applications span across low-voltage industrial installations, commercial buildings, and civil infrastructure. Typical environments include main distribution boards (MDBs), sub-distribution panels, motor control centers (MCCs), and uninterruptible power supply (UPS) systems. They are also prevalent in renewable energy setups, such as photovoltaic (PV) arrays and wind turbine converters, where robust protection against overloads and short circuits is critical. The Tmax series excels in applications requiring high short-circuit withstand capability and selective coordination, ensuring system stability and minimizing downtime in critical processes.
The category encompasses several distinct subcategories and product codes. Key series include the Tmax T1, T2, T3, T4, T5, T6, and T7, each corresponding to specific frame sizes and current ratings. For example, the Tmax T4 series typically covers ratings from 160A to 250A, while the T7 series handles up to 3200A. Product codes often follow a pattern like 'T4N250' or 'T5S630', where the letter indicates the breaking capacity class (e.g., N for normal, S for standard, H for high, L for very high) and the number denotes the rated current in amperes. Electronic trip units are designated with suffixes like 'Ekip' (e.g., T5S630 Ekip Dip). These breakers are available in fixed, plug-in, and withdrawable versions to suit different maintenance and operational requirements.
