1+N pole configuration B-trip characteristic 6kA breaking capacity 230V AC rated voltage DIN rail mountable Fast tripping for low overcurrents

Product description

The Siemens 5SY6506-6 is a 1+N-pole miniature circuit breaker featuring a B-trip characteristic, a 6A current rating, and a 6kA breaking capacity at 230V AC. The Type B characteristic makes it ideal for circuits with very low inrush currents, such as those protecting sensitive electronic equipment or long cable runs.

This breaker's 1+N pole design ensures simultaneous switching of live and neutral conductors for complete circuit isolation. It is commonly used in residential applications, for protecting sensitive electronics, and in control systems where rapid tripping for low overcurrents is required.

Frequently asked questions

What is the difference between a Type B and Type C tripping characteristic?

A Type B tripping characteristic (like in the 5SY6506-6) trips between 3 to 5 times the rated current, making it suitable for sensitive electronics and long cables. A Type C characteristic trips between 5 to 10 times the rated current, offering more tolerance for inrush currents common in general applications or motors.
