Why Choose the IMO LB69-4063 Switch Disconnector?
The IMO LB69-4063 is a robust 4-pole switch disconnector engineered for safe and dependable electrical isolation in industrial machinery, control panels and power distribution systems. Part of the established IMO LB69 Series, this non-fused isolator is well suited to panel builders, OEMs, electrical contractors and maintenance engineers.
Its four-pole switching arrangement allows three phase conductors and the neutral to be disconnected simultaneously. This makes the LB69-4063 particularly suitable for installations where complete isolation is required during inspection, servicing, repair or emergency shutdown procedures.
Offering an AC-21 rated current of 63 A, an AC-23 operational current of 45 A and a rated operational voltage of up to 690 V AC, the IMO LB69-4063 provides reliable switching for demanding industrial loads. The isolator body can be paired with compatible IMO extension shafts and external handles to create a practical door-coupled operating system.
Key Advantages
- 63 A AC-21 rated current for industrial isolation applications.
- 45 A AC-23 operational current for demanding inductive loads.
- 4-pole switching for simultaneous phase and neutral isolation.
- Rated operational voltage of up to 690 V AC.
- Compatible with suitable IMO extension shafts and external handles.
- Provides secure manual isolation for maintenance and servicing.
Key Features

- Suitable for door-coupled operation with compatible accessories.
Reliable Isolation for Industrial Electrical Systems
The IMO LB69-4063 provides a clearly defined method of separating machinery and electrical equipment from the incoming supply. Its manually operated switching mechanism supports safer maintenance procedures by helping prevent equipment from remaining energised while work is being completed.
The four-pole configuration is especially useful in systems where the neutral conductor must be disconnected alongside the three phases. When installed with an appropriate IMO extension shaft and external operating handle, the isolator can be operated from the enclosure door while the switching body remains securely mounted inside the panel.
Typical Applications
- Industrial control panels and switchboards.
- Three-phase systems requiring neutral isolation.
- Motor control and machinery isolation.
- Manufacturing and production equipment.
- OEM machinery and automation systems.
- Power distribution equipment.
- Maintenance and emergency isolation.
