3RV1021-4DA10

The Siemens 3RV1021-4DA10 circuit breaker exemplifies reliability in electrical applications. Capable of managing an operating voltage of 690 volts, this device is suitable for various uses. With a provision for auxiliary switches, it allows additional functionalities. This circuit breaker exhibits a typical active power loss of 8 watts, ensuring efficient operation. It is resistant to surge voltages up to 6000 volts, giving it considerable durability in demanding environments.

The device employs a thermomagnetic system for both overcurrent and short-circuit protection, which provides an effective safety mechanism. Its mechanical service life is notable, offering around 100,000 switching cycles for the main contacts, ensuring longevity in performance. Furthermore, the circuit breaker can function with an operating current of 25 amps in a 400V, three-phase setup while managing a maximum power of 11 kW.

It is designed to be mounted in any orientation and is compatible with standard 35 mm DIN rails, promoting versatility during installation. The environmental operation range extends from -20 degrees to 60 degrees Celsius, making it adaptable to varying ambient conditions. With an IP20 protection rating, it offers adequate shielding against solid foreign objects but is not waterproof. This makes it ideal for controlled environments within industrial settings.
