Protection Function and Operating Principle

The primary function of ABB SH202-6C is to protect electrical circuits from damage caused by excessive current. Electrical systems may experience abnormal conditions such as continuous overload or sudden short circuit faults. The circuit breaker is designed to detect these conditions and disconnect the affected circuit to improve system safety.

During overload situations, the internal thermal protection mechanism responds according to the amount of current passing through the device. When excessive current continues for a certain period, the thermal element activates the tripping mechanism and interrupts the circuit. This helps reduce the possibility of overheating in cables and connected electrical equipment.

During short circuit conditions, the electromagnetic release mechanism provides fast operation. The rapid response helps limit the effect of high fault currents and protects electrical components from severe damage.

The C characteristic curve allows ABB SH202-6C to support circuits where moderate temporary current peaks may occur during equipment startup. This characteristic provides a balance between avoiding unnecessary tripping and maintaining effective protection against dangerous fault conditions.
