The MAS64-250A-4P is a heavy-duty mild steel enclosed switch disconnector designed to provide safe and dependable isolation of low-voltage electrical circuits in demanding industrial, commercial and infrastructure applications. Incorporating a high-quality ABB 4-pole switch disconnector, the assembly delivers reliable switching performance for three-phase electrical distribution systems with higher current requirements.
The switchgear is housed within a robust powder-coated mild steel enclosure finished in RAL 7035. Its durable construction provides excellent protection against dust, water ingress and accidental mechanical damage, while the removable galvanised mounting plate, bottom gland plate and internal earthing points support efficient installation and cable management.
With a rated operational current of 250 A, a 4-pole switched-neutral configuration and suitability for 415–440 V AC systems, the MAS64-250A-4P is ideal for industrial machinery, manufacturing plants, commercial buildings, utilities and infrastructure projects requiring secure high-current electrical isolation.
The MAS64-250A-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 supply.
The ABB switch disconnector provides dependable operation under demanding electrical loads, while the IP66 mild steel enclosure protects the internal equipment in challenging industrial environments. The external rotary handle gives a clear visual indication of the switch position and can be padlocked in the OFF position to help prevent accidental or unauthorised re-energisation.
