The MAS64-315A-4P is a heavy-duty mild steel enclosed switch disconnector engineered to provide safe and dependable isolation of low-voltage electrical circuits in demanding industrial, commercial and infrastructure applications. Incorporating a premium ABB 4-pole switch disconnector, the assembly delivers reliable switching performance for high-current three-phase electrical distribution systems.
The switchgear is housed within a durable powder-coated mild steel enclosure finished in RAL 7035, providing excellent protection against dust, water ingress and mechanical damage. The enclosure includes a removable galvanised mounting plate, lower gland plate, internal earthing points and IP20 terminal shrouds for straightforward installation and long-term reliability.
With a rated operational current of 315 A, a 4-pole switched neutral configuration and suitability for 415–440 V AC systems, the MAS64-315A-4P is ideal for industrial machinery, manufacturing plants, commercial buildings, utilities and infrastructure projects requiring dependable high-current electrical isolation.
The MAS64-315A-4P provides safe manual isolation of three-phase electrical supplies during maintenance, servicing and emergency shutdown procedures. The ABB switch disconnector delivers dependable switching performance while the robust steel enclosure protects internal equipment against harsh industrial environments. The external rotary handle provides clear ON/OFF indication and can be padlocked in the OFF position for additional maintenance safety.
Purpose-built for demanding industrial installations, the enclosure offers generous internal wiring space, making cable routing and termination straightforward while maintaining excellent accessibility for installers and maintenance engineers.
