MAS43-80A-4P Mild Steel Enclosed 80A Switch Disconnect 4 Pole
£390.80
Why Choose the MAS43-80A-4P Mild Steel Enclosed Switch Disconnector?
The MAS43-80A-4P is a robust mild steel enclosed switch disconnector designed to provide safe and reliable isolation of low-voltage electrical circuits in industrial, commercial and infrastructure applications. Incorporating a high-quality ABB 4-pole switch disconnector, the unit delivers dependable switching performance for three-phase electrical distribution systems.
The switchgear is installed within a durable powder-coated mild steel enclosure finished in RAL 7035. Its strong construction provides excellent protection against dust, water ingress and mechanical damage, while the removable galvanised mounting plate, lower gland plate and internal earthing points support straightforward installation and cable management.
With a rated operational current of 80 A, a 4-pole switched-neutral configuration and suitability for 415–440 V AC systems, the MAS43-80A-4P is ideal for machinery isolation, manufacturing facilities, commercial buildings and industrial power distribution applications.
