Rated breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. At 690 V the 17 kA figure still covers most industrial motor-drive branches.
Thermal derating and panel fill
Front IP40 protects against tool entry; the body is open-frame behind the panel.
Sourcing and fit
This is a current-production Siemens SENTRON part, sourced from multiple distribution channels. Availability and pricing confirmed at RFQ time — send the order code for a quote.
