CLASS 20 allows for a longer trip time of 20 seconds. The 3RV2041-4HA10 is a CLASS 10 device, suitable for standard motor start-ups.</p> <strong>Can this circuit breaker be used in a single-phase application?</strong><br><p>Yes, although it is a 3-pole device, it can be used for single-phase motor protection. For proper operation, all three poles must be wired in series to ensure the thermal overload mechanism functions correctly. Please consult the Siemens manual for the correct wiring diagram.</p> <strong>What is the short-circuit breaking capacity (Icu) of this device at 400V?</strong><br><p>According to the technical data on the device, the ultimate short-circuit breaking capacity (Icu) at 400V is 65 kA, and the service short-circuit breaking capacity (Ics) is 30 kA. This ensures high system availability and safety.</p> <p><em>profideals is not an authorized distributor, reseller or representative of the products featured on this website.
