The Schneider PRD1 25 3P+N is a Residual Current Circuit Breaker with Overload Protection (RCBO), designed to offer earth leakage protection and overload protection for 3-phase electrical circuits with neutral.
Parameters:
Rated Current (In): 25A
Poles: 3P+N (3-pole configuration with neutral, ideal for 3-phase systems with neutral protection)
Rated Voltage (Un): 400V AC (standard voltage for 3-phase systems)
Residual Current Sensitivity (IΔn): Typically 30mA (used for personnel protection; other sensitivities may be available based on local requirements)
Rated Frequency: 50/60Hz
Breaking Capacity (Icu): 10kA (maximum fault current the RCBO can safely interrupt)
Overload Protection: Yes, provides thermal overload protection, which will trip the device if the current exceeds the rated value for an extended period.
Short Circuit Protection: Yes, provides magnetic protection, which trips instantly in the event of a short circuit, preventing circuit damage.
Insulation Resistance: ≥ 100MΩ (at 500V DC)
Ambient Temperature Range: -25°C to +60°C (suitable for a wide range of environmental conditions)
Mechanical Durability: 20,000 operations
Electrical Durability: 4,000 operations (under rated current and short-circuit conditions)
