The Siemens 3RV20110CA10 is a motor protection circuit breaker from the SIRIUS 3RV2 series. It is designed for robust protection with a thermal overload release and a fixed N-release of 3.3 A. The breaker operates with a 3-pole main current circuit and supports a wide operating voltage range from 20 to 690 V.
Key electrical specifications include a rated operational current of 0.25 A at AC-3 and AC-3e, with a maximum breaking capacity of 100 kA at various voltages up to 690 V. The trip class is CLASS 10, ensuring reliable protection for motors.
This circuit breaker is suitable for mounting on a DIN rail and operates within an ambient temperature range of -20 to +60 °C. It also meets ATEX directive requirements for use in potentially explosive atmospheres.
Additional features include phase failure detection and a mechanical service life of up to 100,000 switching cycles. The breaker is compatible with contactor sizes S00 and S0.
The adjustable current response value for the current-dependent overload release is 0.18 to 0.25 A.
The maximum short-circuit breaking capacity (Icu) is 100 kA at AC voltages from 240 V to 690 V. The operating short-circuit breaking capacity (Ics) is also 100 kA.
The ambient temperature during operation is -20 to +60 °C.
The rated operating voltage range is 20 to 690 V AC.
It is approved by ATEX, CCC, CSA, EAC, IECEx, and UL.
The mounting type is DIN Rail.
Yes, phase failure detection is included.
