The Schneider NSX 3P 630N 600A 6.3E is a 3-pole molded case circuit breaker (MCCB) from the NSX series, designed for overload and short-circuit protection in high-current, three-phase electrical systems.
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 600A
Frame Size: 630N (denotes the frame size, ensuring that it can carry and protect circuits rated up to 600A)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal-Magnetic Protection: The breaker offers both thermal protection for overload conditions and magnetic protection for short circuits.
Adjustable Thermal and Magnetic Settings: The 6.3E indicates adjustable thermal settings (for overload protection) and adjustable magnetic settings (for short-circuit protection), allowing for customized protection based on the specific load and application needs.
Magnetic Trip: Provides instantaneous disconnection when a short circuit is detected, minimizing the risk of damage to electrical equipment.
Breaking Capacity: Typically 50 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Disconnects the circuit when the current exceeds the rated value for a prolonged period, preventing overheating and damage to the system.
Short-Circuit Protection: Provides rapid disconnection when a short circuit occurs, protecting sensitive electrical components from damage.
Manual Reset: After tripping, the breaker can be manually reset once the fault is cleared and the system is safe to reconnect.
