The Schneider NSX100F DC 3P 63A is a Molded Case Circuit Breaker (MCCB) designed to provide overcurrent protection for direct current (DC) electrical circuits.
Parameters:
Rated Current (In): 63A
Poles: 3P (3-pole configuration, suitable for 3-phase DC systems)
Rated Voltage (Un): 250V DC (standard voltage for DC circuits in industrial and renewable energy systems)
Rated Frequency: DC (direct current systems)
Breaking Capacity (Icu): 10kA (maximum fault current the breaker can safely interrupt without damage)
Overload Protection: Yes, provides thermal overload protection, which ensures the breaker trips when the current exceeds the rated value for a prolonged period.
Short Circuit Protection: Yes, the magnetic protection ensures the breaker trips instantly in the event of a short circuit.
Insulation Resistance: ≥ 100MΩ (at 500V DC)
Ambient Temperature Range: -25°C to +70°C (suitable for diverse environments)
Mechanical Durability: 20,000 operations
Electrical Durability: 10,000 operations (under rated current and short-circuit conditions)
Auxiliary Contacts: Available for additional signaling and monitoring requirements.
