ABB MBT244 is a 2-panel-width CombiLine N expansion module prepared for two NH2 fuse switch disconnectors with a 3-pole busbar system, 72 space units and a maximum rated current of 440 A.
Why Choose the ABB MBT244 NH2 Fuse Switch Expansion 2PW?
The ABB MBT244 is a CombiLine NH2 fuse switch disconnector expansion module designed for integrating high-current fuse switching into compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041783R9999, it forms part of the ABB DESUJ Sub Distribution product group and is supplied as an unassembled, unequipped kit ready for the installation of compatible NH2 fuse switch disconnectors.
Designed for a 2-panel-width (2PW) configuration, the MBT244 measures 450 × 500 × 215 mm and provides 72 space units. The module is prepared for the installation of 2 NH2 fuse switch disconnectors and incorporates a 3-pole busbar system, providing a structured solution for fused power distribution within CombiLine assemblies.
The MBT244 supports a maximum rated current of 440 A in its single-level arrangement. Plastic covers with cut-outs, finished in RAL 7035 and secured using 90-degree press-and-turn fasteners, provide a professional cabinet finish. The module can be used from a cabinet depth of 215 mm, while the compatible EDF or WR mounting frame and NH2 fuse switch disconnectors must be ordered separately.
Key Advantages
Designed for installation of 2 NH2 fuse switch disconnectors.
Supports a maximum rated current of 440 A.
Integrated 3-pole busbar system for structured power distribution.
2-panel-width (2PW) format provides space for two NH2 switching positions.
72 space units support systematic CombiLine cabinet planning.
Compatible with both EDF and WR mounting-frame systems.
Compatible EDF or WR mounting frame ordered separately.
NH2 Fused Power Distribution up to 440 A
The ABB MBT244 provides a dedicated mounting field for two NH2 fuse switch disconnectors, allowing high-current circuits to be switched and protected within a structured CombiLine distribution assembly. Its 3-pole busbar system supports a maximum rated current of 440 A, making the module suitable for substantial commercial and industrial distribution duties.
The MBT244 is supplied unequipped, allowing compatible NH2 fuse switch disconnectors to be selected separately for the application. Its 450 × 500 mm modular footprint provides 72 space units, while the cut-out covers maintain accessibility to the installed switching equipment. Cabinet depth must be considered carefully around the operating and locking area, with a minimum installation depth of 215 mm.
