It's a line-protection version, meaning it's tuned for feeder and distribution duty rather than motor-starting profiles. Breaking capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That's a high-interrupting rating for a 16 A frame — this breaker handles fault currents that would weld a standard MCCB's contacts shut. 3-pole design fits three-phase circuits up to 690 V line-to-line.
Derating and thermal curve
Above that, it derates: 15.36 A at 55 °C, 15.04 A at 60 °C, 14.72 A at 65 °C, and 14.4 A at 70 °C.
Auxiliary and undervoltage release
The UVR design is listed as 3VA9608-0BB24. Two auxiliary switches (HQ type) are built in for remote status indication — one NO/NC pair for breaker open/closed, another for trip signal. No communication module or ground-fault monitoring on this variant.
Panel fit and environment
The storage range exceeds the operating range — that's for handling and warehousing, not running.
