Specifications General Product Type: Miniature Circuit Breaker (MCB) Model: EZD160S Configuration: 3P (three-pole) Rated Current (In): 125A Mounting: DIN rail Application: Overload and short-circuit protection for three-phase electrical circuits Electrical Ratings Rated Operational Voltage (Ue): 400V AC (Three-phase) Rated Insulation Voltage (Ui): 690V AC Rated Impulse Withstand Voltage (Uimp): 6kV Short-Circuit Withstand Capacity (Icu): 10kA Rated Frequency: 50/60Hz Overload Protection: Thermal mechanism Short-Circuit Protection: Magnetic mechanism Trip Curve: Typically C-curve (General-purpose, moderate inrush currents) Protection & Trip Characteristics Thermal Overload Protection: The thermal element protects against sustained overload currents, automatically tripping the breaker if the current exceeds the rated value for a certain time. Short-Circuit Protection: The magnetic trip mechanism provides instantaneous protection for high fault currents, ensuring that the breaker trips quickly to prevent damage to the circuit. Adjustable Settings: The trip unit settings are adjustable to suit various overload and fault conditions for different applications.
