Schneider NSX400F 4P 400A MCCB

Schneider NSX400F 4P 400A MCCB is a high-capacity moulded case circuit breaker designed for electrical distribution applications where dependable overload and short-circuit protection is required. This ComPacT NSX400F configuration uses a MicroLogic 2.3 electronic trip unit and provides 4-pole protection for suitable low-voltage AC distribution systems.

The breaker has a 400A rated current at 40°C and a rated operational voltage of up to 690V AC. At 380/415V AC, the NSX400F has a 36kA ultimate short-circuit breaking capacity, making it suitable for a wide range of commercial, industrial and power-distribution applications. Schneider documentation specifies IEC 60947-2 compliance and identifies the device as a Category A circuit breaker.

The MicroLogic 2.3 electronic trip unit provides adjustable long-time and short-time protection, together with instantaneous protection. This adjustment capability allows the protection settings to be selected according to the requirements of the electrical installation rather than treating every application as a fixed-current arrangement. Schneider’s product information lists nine long-time pickup adjustment settings for the relevant configuration.

For customers looking for a Schneider NSX400F 4P MCCB in Pakistan, correct model identification is particularly important because NSX400F products are available with different trip units, ratings and accessories. The exact reference should therefore be checked against the required protection characteristics and installation requirements before ordering.

The 4-pole configuration can be useful in distribution systems where switching and protection requirements extend across three phases and neutral. The breaker is a fixed-mount design and supports optional accessories depending on the specific configuration. The published dimensions for the 4-pole version are approximately 185 × 255 × 110 mm.

HN Electric can provide product availability and pricing information for customers in Lahore and across Pakistan. Before purchase, confirm the exact Schneider reference, trip-unit configuration, breaking capacity, accessories and required quantity with the supplier.

Important: the older LV432677 reference has been discontinued by Schneider Electric and Schneider lists C40F42D400 as its recommended replacement. If the product being sold is advertised under LV432677, verify the exact manufacturer reference and product generation before listing it as new stock.
