The Siemens 3RV20314XA10 is a robust circuit breaker from the SIRIUS 3RV2 series, specifically engineered for motor protection applications. This size S2 device offers a thermal overload release with an adjustable current response range of 49 to 59 Amps and a CLASS 10 trip class, ensuring reliable protection against overcurrents.
With a 3-pole configuration, it operates at a rated voltage of up to 690V and provides an operational current of 59A at 400V (AC-3 and AC-3e). The breaker boasts a high breaking capacity, with a maximum short-circuit current (Icu) of 65 kA at 240V and 400V. It also features phase failure detection for enhanced safety.
Designed for easy installation, it supports DIN rail mounting. The device operates within an ambient temperature range of -20 to +60°C and has a mechanical and electrical endurance of typically 20,000 switching cycles. It is also certified according to ATEX directive 2014/34/EU for use in potentially explosive atmospheres.
