Siemens Motor Protection Circuit Breaker, 10 to 16A Current Rating - 3RV2 Series - 3RV2021-4AA10


This circuit breaker from Siemens is ideal for protecting motors from damage caused by an overcurrent or short circuit. It has an impulse voltage resistance of 6kV (kilovolts) and an insulation capacity of 690V (volts) for robust protection. Thanks to its compact dimensions of 97 (length) x 45 (width) x 91mm (depth), it takes up a minimal amount of space. The unit is part of Siemens' SIRIUS Innovations range for creating modular systems of contactors, overload relays and motor starter protectors.

• Long mechanical service life of 100,000 switching cycles for long-lasting performance

• Power loss of only 7W (watts) for improved efficiency

• IP20 (ingress protection) rating means it's finger-proof and protected against objects greater than 12mm in size

• Wide operating temperature range of -20°C to +60°C for use in demanding environments

Does this component offer any shock protection?


Yes, this circuit breaker provides protection of up to 25g/11ms (milliseconds) for effective resistance to shock.

How should I install this circuit breaker?


This breaker is simple to install using a screw connection or spring clamp to attach it to a standard DIN rail.
