Protection Function

The primary purpose of ABB SH201-15C is to protect electrical circuits from damage caused by excessive current. The device uses thermal protection technology to respond to continuous overload situations and electromagnetic protection technology to react quickly during short circuit events.

When an electrical circuit experiences a prolonged overload condition, the internal thermal release mechanism detects the increase in current and disconnects the circuit after reaching the required operating condition. This helps prevent overheating of cables and connected electrical components.

During short circuit conditions, the electromagnetic release mechanism provides rapid circuit interruption. This fast response helps reduce the impact of fault currents and improves the overall safety of electrical installations.

The C characteristic curve of ABB SH201-15C allows the device to handle moderate temporary current peaks generated by certain electrical equipment while maintaining effective protection against dangerous fault conditions. This makes it suitable for circuits containing equipment with higher initial current requirements.
