PE69-4080 IMO Isolator 4 Pole, 80A Enclosed, IP66

Why Choose the IMO PE69-4080 Enclosed Isolator Switch?

The IMO PE69-4080 is a heavy-duty 4-pole enclosed switch disconnector designed to provide safe and dependable electrical isolation for industrial machinery, commercial installations, distribution systems and OEM equipment. Part of the established IMO 69 Series, it disconnects all three phase conductors and the neutral conductor simultaneously during maintenance, servicing and emergency shutdown procedures.

The PE69-4080 is housed in a robust IP66 and NEMA 4X-rated enclosure, offering effective protection against dust and water ingress in demanding industrial environments. An interlocked external rotary handle provides clear ON and OFF indication and can be secured with up to three padlocks in the OFF position to support safe lockout procedures.

With an 80 A AC-21A operational rating, a 45 A AC-23 main-switch rating at 400 V and an AC-23B motor switching capacity of 22 kW at 380–440 V AC, the IMO PE69-4080 is suitable for isolating larger motors, pumps, compressors, HVAC systems, production machinery and three-phase distribution circuits requiring switched-neutral isolation.

Reliable Isolation for Higher-Current Electrical Systems

The IMO PE69-4080 provides a clear and secure means of disconnecting higher-current three-phase equipment before inspection, maintenance or repair work begins. Its 4-pole configuration isolates all three phase conductors together with the neutral conductor, providing complete circuit disconnection where switched-neutral isolation is required.

Its heavy-duty switching mechanism and weather-resistant enclosure make it suitable for factories, processing plants, commercial buildings and OEM machinery. The spacious enclosure also provides practical access for larger conductors and cable glands.

The interlocked rotary handle helps prevent the enclosure from being opened while the switch is in the ON position. During maintenance, the handle can be secured in the OFF position with up to three padlocks to help prevent accidental or unauthorised reconnection.

Typical Applications

• Industrial machinery and production equipment.
• Three-phase and neutral distribution circuits.
• Large motors, pumps and compressors.
• HVAC and refrigeration systems.
• Conveyors and material-handling equipment.
• Process automation systems.
• OEM control panels and machinery.
• Commercial and industrial power isolation.
