Parameters: Rated Current (In): 125A Poles: 4P (Four-pole configuration, providing protection for 3-phase systems with neutral) Rated Voltage (Un): 415V AC (suitable for 3-phase electrical systems) Rated Frequency: 50/60Hz Residual Current Rating (IΔn): 300mA (earth leakage current sensitivity) Rated Short-Circuit Breaking Capacity (Icn): 10kA (maximum fault current the MCB can safely interrupt) Tripping Curve: C-curve (ideal for moderate inrush currents, such as in lighting and HVAC systems) Overload Protection: Yes, the MCB provides thermal overload protection that trips the breaker when the current exceeds the rated value for a prolonged period. Short Circuit Protection: Yes, the breaker offers magnetic short-circuit protection to instantly disconnect the circuit in case of a short-circuit. Residual Current Protection (RCD): Yes, the 300mA residual current protection offers earth fault protection, reducing the risk of electric shock and potential fire hazards caused by leakage currents. Insulation Resistance: ≥ 100MΩ (at 500V DC) Ambient Temperature Range: -25°C to +60°C (suitable for a variety of environmental conditions) Mechanical Durability: 20,000 operations Electrical Durability: 4,000 operations (under rated current and short-circuit conditions) Auxiliary Contacts: Available for remote monitoring or signaling.
