Circuit breakers, Type CTI MB - DANFOSS INDUSTRIAL AUTOMATION

Circuit breakers, Type CTI MB from Danfoss Industrial Automation, are high-performance molded case circuit breakers (MCCBs) designed for reliable overcurrent and short-circuit protection in industrial power distribution systems. These devices are available in various pole configurations (3P, 4P) and rated currents from 16 A up to 1600 A, with breaking capacities up to 100 kA at 415 V AC. They feature adjustable thermal-magnetic or electronic trip units, ensuring precise coordination and selectivity. The CTI MB series supports fixed or plug-in mounting, and includes accessories like auxiliary contacts, shunt trips, and undervoltage releases. With a rated insulation voltage of 1000 V and operational voltage up to 690 V AC, these breakers are suitable for both AC and DC applications, offering high durability and compliance with international standards (IEC 60947-2).

These circuit breakers are primarily used in industrial switchboards, motor control centers (MCCs), and power distribution panels for factories, commercial buildings, and infrastructure projects. They are ideal for protecting transformers, generators, motors, and cables in environments requiring high short-circuit withstand capability. Common sectors include manufacturing, oil and gas, water treatment, renewable energy (solar and wind), and data centers. The CTI MB series is also applied in marine and offshore installations due to its robust design and resistance to harsh conditions.

The main subcategories within the CTI MB series include fixed and withdrawable versions, with electronic trip units (ETU) for advanced protection. Key article codes follow the pattern: CTI-MB-3P-160A (3-pole, 160 A), CTI-MB-4P-630A (4-pole, 630 A), and CTI-MB-3P-1000A. These codes typically include pole count, rated current, and trip unit type (e.g., CTI-MB-3P-250A-ETU). Accessories like auxiliary contact blocks (CTI-MB-AUX) and motor operators (CTI-MB-MO) are also available. For exact specifications, refer to the Danfoss catalog or our product pages.
