Product description

The Siemens 5SJ4206-8HG42 is a 2-pole circuit breaker with a D-curve trip characteristic, designed for applications that require protection against overcurrents while accommodating high inrush currents. It features a 6A rating, a 10kA interrupting capacity, and is UL 489 listed for 480Y/277V AC systems.

This breaker is particularly suitable for protecting circuits with inductive loads such as motors and transformers, where significant temporary current surges occur during startup. The D-curve prevents nuisance tripping from these inrush currents, ensuring reliable operation.
