Siemens 3RV2021-1AA15

The circuit breaker, designated as 3RV2, is designed for motor protection with a rated permanent current of 2 amperes. It operates within a voltage range of 690 volts and is equipped with a magnetic release system. The unit includes a total of three poles and features both normally open and normally closed auxiliary contacts, specifically one of each type.

With an IP20 protection rating, this breaker is sensitive to phase failure and is capable of handling a short-circuit breaking capacity of up to 100,000 amperes at 400 V, 50 Hz. The power loss per pole is 2.4 watts, and it provides a rated operating power of 1 kilowatt at 400 V under AC-3 conditions.

Notably, the overload trip settings range from 1.1 to 1.6 amperes, allowing for precise adjustments according to application needs. However, it is important to note that this model does not support mounting onto standard rails and does not include an integrated undervoltage tripper.
