Additional Details:

The 5SY8113-8 MCB is characterized by its current rating (e.g., 13A) and tripping characteristic (e.g., C-curve). The C-curve indicates that the MCB is suitable for circuits with moderate inrush currents. The thermal-magnetic trip mechanism provides both overload and short-circuit protection. The overload protection is achieved by a thermal element that trips the breaker when the current exceeds the rated value for a prolonged period. The short-circuit protection is provided by a magnetic element that trips the breaker instantaneously when a high fault current is detected. The trip-free mechanism ensures that the breaker trips even if the handle is held in the ON position. The clear contact position indicator shows whether the breaker is ON or OFF. The MCB is designed for DIN rail mounting, making it easy to install in standard electrical panels.
