Compact NSX DC & DC PV direct current molded case circuit breakers ( MCCB) and switch disconnectors are used for circuit control and disconnection for low voltage distribution systems. The range comes in three frame sizes with a wealth of compatible accessories and auxiliaries compatible with Compact NS & NSX AC circuit breakers and disconnectors, including for motor mechanism and manual source-changeovers (Transferpact).


  • Flexible installation: any position; switchboard or wall-mounted.

  • Breaking capacities for the 2 sizes for the molded case circuit breakers (MCCB).

  • Compact NSX DC up to 1200 A: up to 100kA and to 750 V DC.

  • Compact NSX DC PV up to 500 A: up to 10kA and to 1000 V DC.

  • Switch disconnectors: 16 A to 1500 A.

  • 1,2, 3 and 4 pole versions available.

  • Manual and remote operation.

  • Fixed and withdrawable versions.

  • Accessories for insulation and series or parallel connection of pole, suited to the particularities of DC applications, including heat sinks, phase barriers, and terminal shields.


    Easy and efficient

  • Usable in any position.

  • Three standardized frame sizes for your convenience.

  • Select, configure, and generate BOM more efficiently and accurately with the Schneider Electric tool MyPact.

  • Compatible accessories

  • Save space, time and effort with the same extended range of accessories as with the Compact NS & NSX AC molded case circuit breakers (MCCB) and switch disconnectors.

  • Manuel source-changeover systems (Transferpact).

  • Specific accessories for your application including heat sinks, terminal shields, serial and parallel connections.
