3RV1021-4AA10

Engineered by Siemens, the 3RV1021-4AA10 circuit breaker stands as a robust solution for motor protection in various industrial applications. With a trip classification of Type 10, this device is designed to monitor and manage electrical currents effectively, mitigating risks associated with motor overload.

This model features three poles and handles a nominal current of 16 A for AC-3 duty at 400 volts. It allows power handling capabilities of around 7.5 kW under these operating conditions. Moreover, the circuit breaker exhibits a remarkable short-circuit breaking capacity, rated at 50 kA for voltages up to 400 V, 10 kA for 500 V, and 4 kA for 690 V.

This unit is suitable for installation at altitudes reaching up to 2000 meters above sea level while maintaining optimal operational parameters. It tolerates an operating temperature range from –20°C to +70°C, ensuring flexibility across diverse environmental conditions.

The device is designed with a typical power dissipation of about 7 watts during standard operations. Its mechanical lifespan is impressive, with an endurance rating approximating 100,000 switch cycles, which is critical for environments requiring frequent switching. Additionally, it features a maximum switching rate of 15 operations per hour, providing timely performance under dynamic conditions. The protection rating of IP20 safeguards against environmental elements without compromising accessibility for maintenance and monitoring.
