It's built for line protection — main feeder or large branch circuit duty — not motor protection or ground-fault monitoring. The interrupting ratings are the headline: 187 kA at 240 VAC, 121 kA at 415 VAC, 75.6 kA at 440 VAC, and 17 kA at 690 VAC.
Above that it steps down: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C. That 70 mm depth is shallow enough for most 200 mm-deep enclosures; the 76.2 mm width (three 25.4 mm pole pitches) is standard for 3-pole MCCBs in a SENTRON panelboard.
Auxiliary and undervoltage release
This variant ships with two HQ auxiliary switches (form C) and an undervoltage release (UVR) built in. The UVR is wired in series with the control voltage — if the control supply drops, the breaker trips. The auxiliary switches are rated for signal-level loads; they'll report breaker status back to a PLC input module. No communication module, no phase-failure detection, no ground-fault monitoring on this build.
