Siemens 3RV2421-4AA10 SIRIUS 3RV2 S0 thermal-magnetic circuit breaker

Product Positioning

The 3RV2421-4AA10 is a Siemens SIRIUS 3RV2 series S0 enclosure thermal-magnetic circuit breaker. Its thermal overload trip is adjustable from 10 to 16A and it also has instantaneous short-circuit trip capability. The manufacturer indicates that it is suitable for transformer circuit protection.

Core Product Advantages and Features

Adjustable current range

The thermal overload trip can be finely adjusted between 10 and 16A according to the actual load current, improving protection accuracy.

Momentary short circuit tripping

The instantaneous magnetic trip value is 286A, which can quickly disconnect the circuit when a short circuit fault occurs.

Screw terminal design

The use of screw terminals makes wiring installation and subsequent maintenance and repair more convenient.

DIN rail mounting

It conforms to 35mm DIN rail specifications and can be directly installed in standard distribution boxes.
