3RV20211HA20

The Siemens SIRIUS 3RV2 series circuit breaker, model 3RV20211HA20, is designed for motor protection applications. It features a thermal magnetic overload release with adjustable current settings ranging from 5.5 to 8 Amperes, and a fixed N-release of 104 A. This breaker is rated for a maximum operating voltage of 690 V and has a breaking capacity of up to 100 kA at 400 V.

With a CLASS 10 trip class and phase failure detection, it provides reliable protection for electrical systems. The device is suitable for DIN rail mounting and has a rotary actuator. Its general technical data includes a power loss of 9.25 W at rated current in hot operating state and an insulation voltage rating of 690 V with degree of pollution 3.

The circuit breaker is built for durability, with a mechanical service life of 100,000 switching cycles for both main and auxiliary contacts, and an electrical endurance of 100,000 cycles. It operates within an ambient temperature range of -20 to +60 °C. The ATEX directive type of protection is Ex II (2) GD, with certificate number DMT 02 ATEX F 001.

Key electrical characteristics include a 3-pole configuration, operational current of 8 A at AC-3 and AC-3e at 400 V, and operating power up to 3 kW at AC-3 at 400 V. The breaker also supports a rated operating frequency of 50 to 60 Hz.
