The Schneider IC65N 4P 63A 300mA S is a type of circuit breaker that combines protection against both overloads and short circuits, while also providing residual current protection.
Parameters:
Rated Current (In): 63A
Rated Voltage (Un): 230/400V AC
Type of Residual Current: S (Selective)
S stands for "Selective" or "Time-delayed" — this version is used to allow selective tripping in the event of earth leakage faults, useful in systems with multiple RCCBs to prevent unnecessary shutdowns.
Rated Residual Operating Current (IΔn): 300mA
Rated Frequency: 50/60Hz
Breaking Capacity (Icn): 10kA (at 230V)
Insulation Resistance: ≥ 100MΩ at 500V DC
Ambient Temperature Range: -25°C to +60°C
Mechanical Durability: 20,000 operations
Electrical Durability: 4,000 operations (at rated current and 30% overload)
