Three poles, so it handles three-phase loads without needing a fourth pole for the neutral. Breaking capacity is where this breaker earns its keep: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and still 3 kA at 690 V. That's a high-interrupting rating for a 100 A frame — it'll clear a bolted fault upstream without the arc flash climbing into the next panel.
What the auxiliary package means for panel wiring
Includes two auxiliary switches, one trip alarm switch, one electrical alarm switch (HQ), and an undervoltage release. Communication function is present on this variant. It can interface with a higher-level system via the SENTRON communication module.
Temperature performance and storage limits
Storage range is wider: -40 °C to 80 °C, which covers most warehouse and shipping conditions. No special cold-weather start-up sequence needed — the breaker is ready at -25 °C.
