Its 160 A continuous rating at 40 °C holds flat through 50 °C, then derates to 144 A at 70 °C. The interrupting capacity is the headline number: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. These are the fault currents the breaker can safely clear without welding or rupturing — critical for sizing upstream protection and verifying SCCR compliance on the panel label.
The 3VA1116-5EF42-0AD0 measures 101.6 mm wide, 130 mm tall, and 70 mm deep. In a washdown or outdoor enclosure, the breaker itself needs a separate IP-rated door or cover. Three auxiliary switches HQ are factory-fitted; no undervoltage release, no ground-fault module, and no N-conductor protection are included. The 15 000 mechanical endurance cycles are typical for a fixed-mounted line-protection MCCB in a distribution board.
