Rated breaking capacity reaches 100 kA at 240 V, 400 V, and 500 V, and 10 kA at 690 V. At 690 V the 10 kA rating still covers typical motor branch circuits in 690 V systems.
Protection features and mounting
Built-in phase failure detection ensures the breaker trips if one phase drops out, preventing single-phasing damage to the motor. Temperature compensation is active over the -20 to +60 °C operating range, so the thermal trip curve stays accurate regardless of panel ambient heat. Mounting position is any orientation, giving flexibility in crowded enclosures.
