SCHNEIDER ELECTRIC NSX250F

SCHNEIDER ELECTRIC NSX250F is heavy-duty moulded case circuit breaker from Schneider ComPact NSX series, rated 250A, available in 3-pole or 4-pole versions. The moulded case circuit breaker has 36kA short-circuit breaking capacity at 415VAC power network. This moulded case circuit breaker can be fitted with TMD thermal-magnetic trip or MicroLogic electronic trip units. The moulded case circuit breaker can be equipped with rich accessories: shunt release, undervoltage release, auxiliary contact and earth leakage protection module.

This breaker provides thermal & magnetic overcurrent protection for low voltage power feeders and heavy motor loads. The thermal & magnetic overcurrent protection uses thermal element to protect against long-time overload. The thermal & magnetic overcurrent protection triggers instantaneous magnetic trip when short-circuit fault occurs. The thermal & magnetic overcurrent protection can connect with DCS via communication modules for power network monitoring. The thermal & magnetic overcurrent protection protects busbars, power cables and downstream electrical assets.

This SCHNEIDER spare is an essential low voltage distribution spare for power panel maintenance and retrofit. The low voltage distribution spare can replace damaged NSX250F breakers directly. The low voltage distribution spare meets IEC, CE and UL international electrical safety standards. The low voltage distribution spare is widely applied in factory, petrochemical and marine low voltage power distribution cabinets.

SCHNEIDER ELECTRIC NSX250F MCCB is a widely used feeder protection device for LV power system. It integrates overload, short-circuit and optional earth fault protection, supports modular accessory installation, ensures fast fault isolation for industrial and marine power networks.
