This Siemens 3RV24314UA10 is a thermal magnetic circuit breaker designed for transformer protection. It features a size S2 designation and a 3-pole configuration for main current circuits.
The breaker has an adjustable current response value ranging from 32A to 40A, with a nominal operational current of 40A at AC-3 and AC-3e ratings. It supports a wide operating voltage range from 20V to 690V, with a maximum rated voltage of 690V for AC-3 and AC-3e applications. The power loss at AC in a hot operating state is 20W.
With a breaking capacity of up to 100 kA at 240V (Icu) and 30 kA at 400V (Ics), this circuit breaker provides robust protection. It includes phase failure detection and operates with a Class 10 trip class. The device is suitable for DIN rail mounting and features a rotary actuator type.
Environmental conditions for operation include an ambient temperature range of -20°C to +60°C and a relative humidity of 10% to 95%. The mechanical service life for both main and auxiliary contacts is a typical 50,000 switching cycles.
