3-pole protection 400V rated 10kA breaking capacity C-curve tripping 2A current rating 70mm depth

Product description

The Siemens 5SY4302-7 is a 3-pole miniature circuit breaker designed for reliable protection in three-phase electrical systems. It operates at 400V with a 10kA breaking capacity and features a C-curve tripping characteristic, suitable for loads with moderate inrush currents. This breaker is rated for 2A and has a standard depth of 70mm.

This 2A, 3-pole circuit breaker with a C-curve is ideal for protecting circuits with moderate inductive loads, such as small motors, control transformers, and lighting systems in three-phase applications. It provides essential safety against overloads and short circuits.
