The Siemens 3RV21214BA10 is a circuit breaker in size S0, specifically designed for motor protection applications with an integrated overload relay function. It operates on a thermal magnetic principle and offers an adjustable current response value for the overload release ranging from 13 to 20 Amps.
This device features 3 poles for the main current circuit and has a rated operational current of 20A. It supports a wide operating voltage range from 20 to 690V, with a maximum rated voltage of 690V for AC-3 and AC-3e applications. The circuit breaker provides a breaking capacity (Icu) of up to 100 kA at 240V AC and 55 kA at 400V AC.
With a CLASS 10 trip class, it is suitable for protecting motors against overloads and phase failures. The unit is designed for DIN rail mounting and features screw terminals for connection. Its mechanical and electrical endurance are rated for a typical 100,000 switching cycles, ensuring reliability in demanding industrial environments.
Environmental conditions for operation include an ambient temperature range of -20 to +60 °C and a relative humidity of 10 to 95%. The circuit breaker also has a shock resistance of 25g / 11 ms according to IEC 60068-2-27.
