It carries a 187 kA interrupting capacity at 240 VAC, dropping to 121 kA at 415 VAC and 440 VAC, 75.6 kA at 500 VAC, and 3.7 kA at 690 VAC — the SCCR headroom you need for high-fault utility feeds or transformer secondaries.
That simplifies panel thermal budgeting: you don't need to oversize for a warm enclosure. The shunt trip release (STL) is factory-fitted, allowing remote tripping from a safety circuit or emergency-stop chain. A communication function is included on this variant, enabling integration with higher-level energy management or monitoring systems without an add-on module. Power loss is capped at 10 W, which keeps heat dissipation manageable in a dense DIN-rail layout.
Verify gland plate clearance for the 86 mm depth, especially in shallow enclosures. The storage limits govern handling and warehousing, not running conditions.
