The Schneider NS 3P 1000A is a 3-pole molded case circuit breaker (MCCB) from Schneider Electric’s NS series, designed to provide reliable protection for electrical systems in industrial, commercial, and infrastructure applications.
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 1000A
Frame Size: 1000A (suitable for circuits carrying up to 1000A of continuous current)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Breaking Capacity:
50 kA at 415V (maximum fault current the breaker can safely interrupt)
65 kA at 480V (maximum fault current at higher voltages)
Tripping Characteristics:
Thermal Protection: Provides overload protection by disconnecting the circuit if the current exceeds the rated value for an extended period.
Magnetic Protection: Provides instantaneous protection against short circuits, disconnecting the circuit quickly to limit damage.
Adjustable Settings: Both thermal and magnetic settings are adjustable to suit the specific needs of the installation.
Protection Functions:
Overload protection
Short-circuit protection
Adjustable settings for both overload and short-circuit protection
Auxiliary Contacts: Optional auxiliary contacts for remote monitoring and control.
Compliance: Complies with international standards such as IEC 60947-2 for low-voltage circuit breakers.
