The Schneider NSX 3P 160A is a 3-pole molded case circuit breaker (MCCB) from the NSX series, designed to provide overload protection, short-circuit protection, and fault current interruption 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: 160A
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Tripping Characteristics:
Thermal Protection: Protects against overload conditions by disconnecting the circuit if the current exceeds the rated value for a sustained period, preventing overheating and damage to cables or connected devices.
Magnetic Protection: Provides instantaneous disconnection in case of short circuits, protecting the system from high fault currents.
Adjustable Settings: The thermal protection and magnetic protection settings are adjustable, allowing the breaker to be configured for specific applications, providing the right level of protection.
Breaking Capacity: Typically 50 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Disconnects the circuit if the current exceeds the rated value for an extended period, preventing damage to wiring and equipment.
Short-Circuit Protection: Provides instantaneous protection by disconnecting the circuit during a short circuit, ensuring the safety of connected systems.
Manual Reset: The breaker can be manually reset once the fault has been cleared, allowing the system to return to normal operation.
