Why Choose the ABB MG303 Modular Expansion?
The ABB MG303 is a CombiLine modular expansion for DIN rail-mounted devices, designed for professional ABB sub-distribution assemblies. Supplied under ABB order code 2CPX041213R9999, the module provides a structured internal installation area for modular electrical devices and is supplied mounted within the cabinet.
The MG303 provides 108 modular space units across three DIN rails, with 36 modular spaces per rail. It uses 35 × 15 mm DIN rails with perforations for wire holders, while the three-field-wide construction incorporates an additional stabilisation profile to provide a secure mounting arrangement.
With dimensions of 450 × 750 × 120 mm, a 125 mm row spacing and compatibility with installation devices according to DIN 43880, the MG303 is designed for efficient integration into CombiLine distribution systems. Plastic covers with cut-outs, 90-degree press-and-turn closures and an RAL 7035 finish complete the modular assembly.
