Why Choose the ABB MA630ALAB OT630E03P Switch Expansion 2PW?
The ABB MA630ALAB, order code 2CPX041374R9999, is a populated load break switch expansion module designed for ABB CombiLine low-voltage sub-distribution systems. Supplied mounted for cabinet installation, it incorporates an ABB OT630E03P 3-pole switch-disconnector to provide reliable high-current switching and isolation within professional electrical distribution assemblies.
Designed for demanding commercial and industrial power distribution, the MA630ALAB has a rated operational current of 630 A. The installed ABB OT630E03P provides 3-pole switching, while the module's mounting cross-member arrangement and protective plastic cover with equipment cut-out provide an integrated solution for incorporating the switch into a compatible CombiLine cabinet.
The MA630ALAB occupies 2 panel widths (PW/FB) and 3 grid units (GU/RE), with dimensions of 450 mm high × 500 mm wide × 260 mm deep and 72 space units (PLE). It is suitable for cabinets from 275 mm deep and is designed for installation using a compatible WR mounting frame, which must be ordered separately.
