Benefits

The Siemens 5SP4491-7RC provides reliable circuit protection for higher-current applications with its 100 A rated current and 10 kA breaking capacity. Its C characteristic makes it suitable for circuits where connected equipment can experience moderate starting or inrush currents.

The 4-pole configuration allows switching and protection across four poles as required by the electrical system design. The SENTRON 5SP4 family also supports compatible accessories for additional signalling and monitoring functions.

For installations with motors, transformers or other loads having significant starting currents, the C characteristic can be appropriate when correctly coordinated with the load and upstream/downstream protective devices.
