The Siemens 3RV20210GA15 is a size S0 circuit breaker from the SIRIUS 3RV2 series, specifically designed for motor protection applications. It offers a thermal magnetic overload release with an adjustable current response value ranging from 0.45 to 0.63 A, and a fixed N-release of 8.2 A. This 3-pole breaker operates with a rated voltage of up to 690V and has a trip class of CLASS 10.
Key electrical specifications include an operational current of 0.63A at AC-3 and AC-3e at 400V, and operating power ratings up to 0.3 kW at 690V. The breaker is equipped with transverse auxiliary switches, providing 1 normally open (NO) and 1 normally closed (NC) contact. It supports a wide operating voltage range from 20 to 690V and operates at frequencies of 50 to 60 Hz.
Designed for reliable performance, the 3RV20210GA15 has a mechanical service life of 100,000 switching cycles for both main and auxiliary contacts. It meets ATEX directive requirements with protection type Ex II (2) GD and holds certificate DMT 02 ATEX F 001. The breaker is suitable for installation at altitudes up to 2,000 meters and operates within an ambient temperature range of -20 to +60 °C.
Mounting is facilitated via DIN rail. The breaker also includes phase failure detection and is rated for a maximum short-circuit current of 1 at 240V AC. Its compliance includes RoHS3, REACH Unaffected, and MSL 1 Unlimited.
