The Siemens 3RV2011-0KA20 circuit breaker is an electrical component specifically designed for motor overload and short - circuit protection.
With a structure size of S00 (45mm wide), its rated current (AC - 3) is 1.25A, current setting range is 0.9 - 1.25A, breaking capacity Icu (KA) is up to 100kA. The tripping device type is A, load class reaches [Tripping Class CLASS10], with 3 poles and no auxiliary contacts. It uses spring terminals, and both its mechanical life and electrical life are 100,000 times, with a maximum frame - level rated current of 16A.
With precise current control and high breaking capacity, this circuit breaker can effectively protect motors from overload and short - circuit hazards. It is suitable for protecting low - power motors and plays an important role in industrial automation and other fields, providing reliable protection for the stable operation of motors.
