It's a current-production part — no obsolescence to chase, no last-time-buy clock ticking. The interrupting capacity is the headline: 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 4.5 kA at 690 V.
Thermal derating and continuous current
Above that, it derates: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Maximum power loss is 48 W, which matters for thermal budgeting in sealed enclosures.
Four auxiliary switches (HQ type) are built in; no undervoltage release or shunt trip on this variant.
Communication and adjustability
Communication function present. Trip unit adjustable: full-scale value 250 A, initial value 50 A. No voltage-trigger or other measurement functions. Line-protection design.
Environmental limits
The operating high end matches the derating curve above.
Lifecycle status is current — Siemens still produces this order code. No replacement to track, no cross-reference needed.
