This Siemens 3RV20314EA15 is a size S2 circuit breaker specifically designed for motor protection applications. It features a thermal magnetic overload release with an adjustable current response value ranging from 22 to 32 A and a CLASS 10 trip class. The breaker operates at a rated voltage of up to 690 V and has an operational current rating of 32 A at 400 V AC-3.
With a breaking capacity of 65 kA at 400 V, this circuit breaker ensures reliable protection against short circuits. It includes transverse auxiliary switches with 1 NO and 1 NC contacts, suitable for control circuits. The device is designed for DIN rail mounting and has a mechanical and electrical endurance of typically 50,000 switching cycles.
Environmental conditions for operation include an ambient temperature range of -20 to +60 °C and a maximum installation altitude of 2,000 m. The circuit breaker also meets ATEX directive requirements for use in potentially explosive atmospheres.
Key electrical specifications include a 3-pole configuration, a rated frequency of 50-60 Hz, and various operating power ratings depending on the voltage and AC-3/AC-3e usage category.
