2CPX041375R9999 ABB MA800ALAB OT800E03P Switch Expansion 2PW

Why Choose the ABB MA800ALAB OT800E03P Switch Expansion 2PW?

The ABB MA800ALAB is a factory-equipped CombiLine switch-disconnector expansion module designed for high-current isolation and switching within compatible ABB low-voltage distribution cabinets. Supplied under ABB order code 2CPX041375R9999, the module incorporates one ABB OT800E03P switch-disconnector with a maximum rated operational current of 800 A.

The MA800ALAB is configured for 2 panel widths (2 PW), with a field width of 500 mm and a module height of 600 mm. Its 4 RE format provides 96 space units, creating a coordinated high-current switching field for commercial and industrial low-voltage distribution assemblies.

The fitted OT800E03P is a 3-pole ABB OT switch-disconnector, providing dependable load switching and circuit isolation. The device is mounted on a cross member and protected by plastic covers with an equipment cut-out, RAL 7035 finish and 90-degree press-and-turn closures. The module is suitable for compatible cabinets from 325 mm depth and requires a separately ordered WR mounting frame.

Reliable High-Current Switching and Isolation

Switch-disconnectors provide controlled load switching together with a defined means of isolating electrical circuits for operational and maintenance requirements. The ABB MA800ALAB combines the CombiLine modular distribution platform with the ABB OT800E03P, providing a coordinated 800 A, 3-pole switching solution for substantial low-voltage distribution circuits.

The factory-equipped arrangement reduces the work required to incorporate a high-current switch-disconnector into a distribution cabinet. Its 2 PW field, dedicated mounting cross member and protective cover system provide an organised installation, while the OT-series device makes the module suitable for main distribution, feeder isolation and other demanding commercial or industrial switching duties.

Typical Applications

• Main low-voltage distribution boards.
• ABB CombiLine distribution assemblies.
• High-current feeder switching and isolation.
• Commercial building electrical distribution.
• Industrial low-voltage switchgear.
• Main switch and distribution cabinet applications.
• Three-phase circuits requiring an 800 A, 3-pole switch-disconnector.
