Its interrupting capacity hits 187 kA at 240 VAC, 121 kA at 415 VAC, and 75.6 kA at 440 VAC — figures that cover most industrial service-entrance and feeder applications where high fault current is expected.
Rated current holds at 16 A from 40 °C through 55 °C, then steps down to 15 A at 60 °C through 70 °C. That flat profile up to 55 °C means no derating in most ventilated enclosures; only tightly-packed or high-ambient panels need the 15 A limit. Maximum power loss is 13.1 W, which is manageable for a 3-pole MCCB of this size.
The auxiliary switch complement (2 form-C + 1 trip alarm HQ) signals position and trip status to a PLC or indicator lamp without extra wiring.
