Description

Overview

The Siemens 3RV2021-4AA10 is a specialized circuit breaker optimized for motor protection. As part of the Siemens SIRIUS 3RV2 generation, it provides reliable protection against short circuits and overloads. This specific model is engineered for Size S0 applications, offering a thermal-magnetic release range of 10 to 16 A and a high instantaneous magnetic trip (N-release) of 208 A.

Key Features & Benefit

  • Space-Saving Design: The S0 frame size allows for high-density installation in control cabinets.

  • Global Compliance: Approved for worldwide use (IEC, UL, CSA), making it ideal for export-oriented machinery.

  • Modular Integration: Seamlessly compatible with SIRIUS contactors and accessories for a complete motor feeder solution.

  • High Reliability: Offers a standard switching capacity with robust mechanical and electrical endurance.

  • Easy Installation: Equipped with classic screw terminals for secure and straightforward wiring.

Function & Application

  • Motor Protection: Provides Class 10 overload protection and short-circuit protection for 3-phase induction motors.

  • Short-Circuit Protection: Features an instantaneous N-release of 208 A to prevent equipment damage.

  • Manual Switching: Functions as a manual On/Off switch for motor circuits.

  • Industrial Use: Perfect for pumps, fans, conveyors, and general machine tool manufacturing.
