The Schneider NSX250F 3P is a 3-pole molded case circuit breaker (MCCB) from the NSX series, designed for overload and short-circuit protection in three-phase electrical systems.
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 250A
Frame Size: NSX250F (denotes the frame size and current rating of the breaker)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal-Magnetic Protection: The breaker provides thermal protection against overloads and magnetic protection for short circuits.
Magnetic Trip: Instantly disconnects the circuit when a short circuit occurs, minimizing the risk of damage to electrical components.
Fixed Thermal Trip Settings: The thermal protection setting is pre-configured, making it ideal for applications where no adjustments are necessary.
Breaking Capacity: Typically 25 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 equipment damage.
Short-Circuit Protection: The breaker trips instantly when a short circuit is detected, protecting the circuit and connected devices.
Manual Reset: After tripping, the breaker can be manually reset once the fault condition is cleared.
