This Siemens 3RV20324WA15 is a robust circuit breaker from the SIRIUS line, specifically designed for motor protection applications. It features a size S2 frame and a thermal magnetic overload release with an adjustable current response value ranging from 42 to 52 A. The breaker is rated for a maximum operational current of 52 A at 400V (AC-3 and AC-3e) and supports a wide operating voltage range from 20 to 690V.
With a trip class of CLASS 10, it provides reliable protection against overloads and short circuits. The unit includes a transverse auxiliary switch with one normally closed (NC) and one normally open (NO) contact. It is designed for DIN rail mounting and has a mechanical and electrical endurance of typically 50,000 switching cycles.
The circuit breaker operates within an ambient temperature range of -20 to +60 °C and has an installation altitude limit of 2,000 meters. It meets ATEX directive requirements with type of protection Ex II (2) GD and carries certificate DMT 02 ATEX F 001. The breaking capacity at 400V AC is rated at 100 kA.
