The Schneider NSX630L 3P 630A is a Molded Case Circuit Breaker (MCCB) designed to provide overcurrent protection for industrial and commercial electrical installations.
Parameters:
Rated Current (In): 630A
Poles: 3P (3-phase protection)
Rated Voltage (Un): 415V AC (for 3-phase systems)
Rated Frequency: 50/60Hz
Breaking Capacity (Icu): 50kA (the maximum fault current the breaker can withstand without being damaged)
Overload Protection: Yes, the MCCB provides overload protection, ensuring it trips when the current exceeds the rated value for an extended period.
Short Circuit Protection: Yes, provides instantaneous tripping in case of a short circuit, protecting the electrical installation and equipment from damage.
