Why Choose the IMO LB69-4080 Switch Disconnector?
The IMO LB69-4080 is a heavy-duty 80 A 4-pole switch disconnector designed for dependable electrical isolation in industrial machinery, control panels and power distribution equipment. Part of the established IMO LB69 Series, this non-fused isolator provides a practical solution for panel builders, OEMs, electrical contractors and maintenance engineers.
Its four-pole switching configuration enables three phase conductors and the neutral to be disconnected simultaneously. This makes the LB69-4080 particularly suitable for installations where complete circuit isolation is required during inspection, servicing, repair or emergency shutdown procedures.
With an 80 A AC-21A rated operational current, a rated operational voltage of up to 690 V AC and an AC-23A motor rating of 15 kW at 400 V, the IMO LB69-4080 delivers reliable switching performance for demanding industrial applications. It supports DIN rail or screw-fixed installation and can be combined with compatible IMO shafts and external handles for door-coupled operation.

Reliable Isolation for Industrial Power Systems
The IMO LB69-4080 provides a clearly defined method of disconnecting 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 inspection or repair work is carried out.
The four-pole configuration is especially useful in systems where the neutral conductor must be isolated alongside the three phases. When installed with a compatible 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.
The handle, shaft and isolator body are normally specified as separate components, allowing the operating arrangement to be selected according to the enclosure depth and application requirements.
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.
- HVAC and building control panels.
- Maintenance and emergency isolation.

What is the current rating of the LB69-4080?
The IMO LB69-4080 has an 80 A rated thermal and AC-21A operational current.
What is the motor rating of the LB69-4080?
It has an AC-23A motor rating of 15 kW at 400 V. Published application data also identifies direct motor switching up to 18.5 kW at 380–440 V, so the relevant IMO technical data should be checked for the specific installation.
How many poles does the LB69-4080 have?
It is a 4-pole switch disconnector, allowing three phase conductors and the neutral conductor to be isolated simultaneously.
Is the LB69-4080 a fused isolator?
No. The LB69-4080 is a non-fused switch disconnector. Appropriate overcurrent and short-circuit protection must be provided separately where required.
Can the LB69-4080 be DIN rail mounted?
Yes. The LB69-4080 supports both DIN rail mounting and screw-fixed installation.
Can it be operated from an enclosure door?
Yes. It can be combined with compatible IMO E69 extension shafts and H69 external operating handles to create a door-coupled isolation arrangement.
Are the handle and shaft included?
The isolator body, operating shaft and external handle are normally supplied as separate components, allowing the correct accessories to be selected for the enclosure.
