The Schneider IID 4P 25A 30mA is a Residual Current Circuit Breaker with Overload Protection (RCBO), designed to provide earth leakage protection along with overload protection for electrical circuits.
Parameters:
Rated Current (In): 25A
Poles: 4P (4-pole design, suitable for 3-phase circuits with neutral protection)
Rated Voltage (Un): 230/400V AC (typical voltage for both single-phase and 3-phase electrical systems)
Residual Operating Current (IΔn): 30mA (designed to trip in the event of earth leakage currents exceeding 30mA, providing protection against electrical shock hazards)
Rated Frequency: 50/60Hz
Rated Insulation Voltage (Ui): 500V
Short-circuit Withstand Capacity (Icn): 6kA (maximum fault current the device can safely interrupt)
Overload Protection: Yes, provides thermal overload protection that ensures the device trips when the current exceeds the rated value for a prolonged period.
Overload Tripping Curve: Suitable for general-purpose loads with moderate inrush currents.
Insulation Resistance: ≥ 100MΩ (at 500V DC)
Ambient Temperature Range: -25°C to +60°C (suitable for various environments)
Mechanical Durability: 20,000 operations
Electrical Durability: 4,000 operations (under rated current and short-circuit conditions)
