E2.2: High-Performance Molded Case Circuit Breakers (MCCBs)
E2.2 refers to a specific frame size within the ABB Emax 2 family of air circuit breakers (ACBs) and molded case circuit breakers (MCCBs), designed for high-current applications. These devices are engineered for selective coordination and protection in low-voltage distribution systems, typically rated for currents up to 3200 A. Key technical parameters include a rated operational voltage of up to 690 V AC, a rated insulation voltage of 1000 V, and a rated impulse withstand voltage of 12 kV. The E2.2 offers breaking capacities (Icu/Ics) up to 200 kA at 440 V AC, depending on the specific configuration. It supports both fixed and withdrawable mounting versions, and is equipped with advanced electronic trip units (e.g., Ekip Touch, Ekip Hi-Touch) for precise protection curves, including L (long-time), S (short-time), I (instantaneous), and G (ground fault) functions. The breaker can be fitted with a range of accessories such as undervoltage releases, shunt trips, auxiliary contacts, and motor operators for remote control.
E2.2 circuit breakers are primarily deployed in main and sub-distribution switchboards within industrial plants, commercial buildings, data centers, and critical infrastructure. They are ideal for applications requiring high short-circuit withstand capability and selective coordination, such as transformer protection, generator protection, and large motor control centers. The E2.2 is also commonly used in marine and offshore installations due to its robust design and compliance with classification societies. Its modular architecture allows integration into power management systems via communication protocols like Modbus RTU, Profibus DP, and Ethernet/IP.
The E2.2 category includes several subcategories and article codes, such as the basic E2.2 N (standard breaking capacity), E2.2 S (high breaking capacity), and E2.2 H (very high breaking capacity). Typical article codes follow the pattern "E2.2N-3200" or "E2.2S-2500", where the suffix indicates the rated current in amperes. Other variants include the E2.2 with Ekip G (ground fault protection) or Ekip D (directional protection) trip units. The main articles are identified by codes like 1SDA104428R1 (E2.2N 3200 fixed) or 1SDA104429R1 (E2.2S 2500 withdrawable). These codes are structured with a base prefix (1SDA) followed by a specific numeric identifier for the configuration.
