Circuit Breakers IZM
Eaton's IZM series represents a comprehensive family of open frame air circuit breakers, engineered for high-current distribution and protection in industrial power systems. These devices are available in four distinct frame sizes, covering nominal current ratings from 800 A up to 6300 A, allowing precise selection for each application's demands. The physical differentiation between sizes lies primarily in width, as all models share a uniform height and depth, simplifying panel layout and busbar connections. Every unit integrates a microprocessor-based trip unit for accurate protection settings, including long-time, short-time, instantaneous, and ground-fault functions. Additionally, external communication modules can be easily connected to enable industrial network protocols such as Profibus DP or Modbus RTU, facilitating integration into supervisory control systems. Eaton complements this range with a wide array of accessories, including motor operators, shunt trips, auxiliary contacts, and mechanical interlocks, achieving remarkable flexibility and operational efficiency.
These circuit breakers are primarily deployed in low-voltage main distribution boards, switchgear assemblies, and power control centers within commercial buildings, data centers, and heavy industrial facilities such as petrochemical plants, steel mills, and manufacturing lines. They serve as main incoming or tie breakers in electrical networks requiring high breaking capacity and selective coordination. Typical applications include generator protection, transformer secondary protection, and large motor feeder circuits where reliability and maintainability are critical.
The IZM series is organized into four main frame sizes: IZM40 (800-4000 A), IZM63 (1600-6300 A), IZM80 (4000-8000 A), and IZM10 (5000-10000 A). Key article codes follow the pattern IZM40-N4, IZM63-H2, etc., where the suffix indicates the number of poles (e.g., N4 for 4-pole) and the breaking capacity class (e.g., H for high, L for low). The trip units are designated as OPTIM 550, 750, or 1050, offering varying levels of metering and communication capabilities. Accessories include the IZM-XTUV undervoltage release, IZM-XSH shunt trip, and IZM-XAU auxiliary switch modules.
