MAS64-400A-4P Mild Steel Enclosed 400A Switch Disconnect 4 Pole
£895.00
Why Choose the MAS64-400A-4P Mild Steel Enclosed Switch Disconnector?
The MAS64-400A-4P is a heavy-duty mild steel enclosed switch disconnector designed to provide safe, reliable isolation of high-current low-voltage electrical circuits. Incorporating a premium ABB 4-pole switch disconnector, this robust assembly is suitable for demanding industrial, commercial and infrastructure power-distribution applications.
The switchgear is housed within a durable powder-coated mild steel enclosure finished in RAL 7035. Its robust construction provides excellent resistance to dust, water ingress and accidental mechanical damage. A removable galvanised mounting plate, lower gland plate, internal earthing points and IP20 terminal shrouds support safe, efficient installation.
With a rated operational current of 400 A, a 4-pole switched-neutral configuration and suitability for 415–440 V AC systems, the MAS64-400A-4P provides dependable high-current isolation for machinery, manufacturing plants, commercial buildings, utilities and infrastructure installations.

Reliable High-Current Electrical Isolation
The MAS64-400A-4P provides a secure means of manually disconnecting three-phase electrical supplies during planned maintenance, equipment servicing and emergency shutdown procedures. Its four-pole arrangement switches the neutral conductor together with all three phases, helping ensure comprehensive isolation from the incoming electrical supply.
The ABB switch disconnector delivers dependable operation under demanding electrical loads, while the IP66 mild steel enclosure protects the internal equipment in challenging industrial environments. The door-coupled rotary handle provides clear ON and OFF indication and can be padlocked in the OFF position to help prevent accidental or unauthorised re-energisation.
Typical Applications
