The Schneider NSX 4P 100F 100A is a 4-pole molded case circuit breaker (MCCB) from the NSX series, designed for protecting electrical circuits in four-wire systems (three-phase with a neutral conductor)
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 4P (4 poles) – Suitable for four-wire systems (three-phase + neutral)
Current Rating: 100A
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal Protection: Provides overload protection by disconnecting the circuit if the current exceeds the rated value for a sustained period, preventing overheating of cables and equipment.
Magnetic Protection: Offers instantaneous protection during short-circuit conditions, ensuring the circuit is rapidly disconnected to prevent significant damage from fault currents.
Fixed Protection Settings: The thermal and magnetic protection settings are pre-configured, simplifying the setup process and making it suitable for standard applications.
Breaking Capacity: 25 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: The breaker disconnects the circuit during sustained overcurrent conditions, preventing damage due to excessive heating.
Short-Circuit Protection: Disconnects the circuit instantly in the event of a short circuit, protecting the system from the high fault currents associated with short-circuit conditions.
Manual Reset: The breaker can be manually reset after it trips, ensuring the circuit can be safely re-energized once the fault is cleared.
