Siemens 3RV2421-1CA10 SIRIUS 3RV2 S0 thermal-magnetic circuit breaker

Product Positioning

The 3RV2421-1CA10 is one of the models with the lowest current rating in the SIRIUS 3RV2 series S0 chassis, with a thermal overload adjustment range of only 1.8 to 2.5A. It is originally marked as a transformer protection specification.

Core Product Advantages and Features

Low current fine adjustment

The thermal overload trip can be finely adjusted between 1.8 and 2.5A, making it suitable for small-capacity circuit protection.

High short-circuit breaking capacity

The rated short-circuit breaking capacity Icu can reach 100kA under 400V and 50Hz conditions.

Momentary short circuit tripping

The instantaneous magnetic trip value is 52A, which, combined with the low current carrying characteristic, quickly disconnects faults.

Standard screw terminals

The main circuit uses screw terminal connections, making installation and wiring operations intuitive and convenient.
