The Schneider PRD 3P+N 12.5KA is a 3-pole + neutral (3P+N) residual current circuit breaker (RCCB) with a 12.5 kA breaking capacity, designed for protecting electrical systems from earth leakage faults and overcurrent conditions.
Specifications:
Type: Residual Current Circuit Breaker (RCCB) with Overload and Short-Circuit Protection
Number of Poles: 3P+N (3 poles + neutral) – Suitable for three-phase systems with a neutral conductor (4-wire systems)
Rated Current: Typically nominal current values range from 10A to 100A, depending on the configuration (ensure the right configuration for your application)
Rated Voltage: 400V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Residual Current Protection (RCD): Offers earth leakage protection, ensuring disconnection if the leakage current exceeds the set threshold, protecting against electrical shocks.
Overload Protection: Disconnects the circuit if the current exceeds the rated value, preventing damage to electrical devices and wiring due to prolonged overcurrent.
Short-Circuit Protection: Provides instantaneous disconnection during short-circuit conditions, preventing damage to circuits and equipment.
Breaking Capacity: 12.5 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Earth Leakage Protection: The RCD component disconnects the circuit when harmful earth leakage currents are detected, providing protection against electric shock hazards and fire risks caused by leakage currents.
Overload Protection: The breaker disconnects the circuit in case of overload conditions, preventing overheating and damage to electrical equipment.
Short-Circuit Protection: Offers instantaneous disconnection during short-circuit situations, ensuring the circuit remains safe.
Manual Reset: The breaker can be manually reset after the fault condition has been cleared, allowing the circuit to be restored to normal operation.
