The 330 kA breaking capacity at 240 V (242 kA at 415 V, 187 kA at 500 V, 6.3 kA at 690 V) means it can safely interrupt fault currents up to those levels without upstream cascading — critical for high-fault installations like transformer secondaries or large motor control centers. Thermal derating is explicit: the breaker carries 250 A up to 50 °C ambient, then steps down to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Communication function is onboard, supporting integration into higher-level energy management systems.
Dimensions: 86 mm depth, 105 mm width, 181 mm height — fits standard MCCB mounting footprints in distribution boards and motor control centers. The 3-pole design with line protection version is sized for feeder or main breaker duty in 250 A circuits. Maximum power loss of 48 W at rated current — account for this in enclosure thermal calculations, especially in sealed or high-density panels.
