Rated 400 A up to 50 °C ambient; above that the continuous current must be derated: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. Maximum power loss is 96 W, which factors into enclosure ventilation planning.
Footprint is 184 mm wide by 248 mm tall by 110 mm deep. The 4-pole body fits standard MCCB mounting patterns in SENTRON distribution boards or third-party enclosures with the appropriate cutout.
Listed as current-production (active lifecycle stage).
187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. These figures apply to the 400 A frame.
