It prevents damage from overloads and short circuits.</p> <h3>Country of Origin</h3> <p>Made in Germany.</p> <h3>CO2 Impact</h3> <p>By purchasing this reused component, you are helping to avoid approximately 38 kg of CO2 emissions that would be generated from manufacturing a new one.</p> <h3>Availability</h3> <p>This item is in stock and ready for immediate dispatch.</p> <h3>FAQ</h3> <p> <strong>Question?</strong><br><p>What is the difference between CLASS 10 and CLASS 20 in this type of motor protection circuit breaker?</p> <strong>Answer:</strong><br><p>CLASS 10, which this 3RV2031-4EB10 unit is, means the breaker will trip within 10 seconds under a locked-rotor condition (starting current). CLASS 20 allows for a longer trip time of up to 20 seconds, suitable for motors with heavy starting loads.</p> <strong>Question?</strong><br><p>Can this circuit breaker be used for single-phase motor protection?</p> <strong>Answer:</strong><br><p>Yes, it is possible to use this three-pole circuit breaker for single-phase applications. You must wire the main circuit through all three poles in series to ensure the thermal overload mechanism functions correctly. Please refer to the official Siemens manual for the correct wiring diagram.</p> <strong>Question?</strong><br><p>What is the N-release value of 416A specified on the label?</p> <strong>Answer:</strong><br><p>The N-release refers to the instantaneous short-circuit trip setting. For this model, it is fixed at 13 times the maximum rated current of the thermal trip (13 x 32A = 416A). This ensures rapid disconnection in the event of a severe short circuit, protecting the equipment and installation.</p> </p> <p><em>spareparts2day is not an authorized distributor, reseller or representative of the products featured on this website.
