The Siemens 3RV20324UA15 is a robust circuit breaker from the SIRIUS 3RV2 series, specifically designed for motor protection applications. This device features a size S2 frame and operates with a thermal magnetic release mechanism, offering a trip class of CLASS 10. It is adjustable for current response values ranging from 32 to 40 A and has a rated operational current of 40 A at 400 V AC-3.
The circuit breaker supports a wide operating voltage range from 20 to 690 V AC, with a maximum rated voltage of 690 V for AC-3 and AC-3e applications. It is equipped with 3 poles for the main circuit and includes a transverse auxiliary switch with 1 normally open (NO) and 1 normally closed (NC) contact. The mechanical and electrical endurance for both main and auxiliary contacts is typically rated at 50,000 switching cycles.
Designed for reliable operation, the 3RV20324UA15 offers phase failure detection and a breaking capacity of 100 kA at 240 V and 400 V AC. It operates within an ambient temperature range of -20 to +60 °C and is suitable for installation at altitudes up to 2,000 meters. The unit is designed for DIN rail mounting, making installation straightforward in control panels and electrical enclosures. Compliance includes ATEX, CCC, CE, CSA, EAC, IECEx, UL, and VDE approvals.
