The Schneider NSX 3P 250H 200A 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: 200A
Frame Size: 250H (indicating the high capacity frame for large current protection)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal Protection: The thermal protection ensures that the breaker trips if the current exceeds the rated value for a prolonged period, protecting the circuit from overheating. The thermal settings are adjustable, providing flexibility for different load conditions.
Magnetic Protection: The magnetic protection provides instantaneous disconnection in the event of a short circuit, preventing severe damage to the circuit.
Adjustable Thermal Settings: The thermal trip settings can be adjusted to accommodate different system requirements, making it versatile for a wide range of applications.
Breaking Capacity: Typically 36 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: The breaker disconnects the circuit when sustained overload conditions are detected, preventing overheating of cables and equipment.
Short-Circuit Protection: Provides instantaneous protection in the event of a short-circuit, ensuring rapid disconnection of the faulted circuit.
Manual Reset: After tripping, the breaker can be manually reset once the fault has been cleared.
