The IMO IS11C (Manufacturer Code: PE69-4080) is a heavy-duty, 4-pole rotary isolator switch. It is a vital manual safety component used to provide a guaranteed physical disconnection of power to high-current machinery, ensuring a safe environment for maintenance or emergency repairs.
The IMO IS11C is a high-performance, surface-mounted rotary isolator designed for demanding industrial and commercial power circuits. Rated at 80A, it sits at the high end of the rotary range, providing reliable isolation for heavy-duty three-phase loads and the neutral line. The switch is housed in a robust, flame-retardant polycarbonate enclosure with an IP66 rating, making it completely dust-tight and resistant to high-pressure water jets from any direction.
For rigorous safety compliance, the unit features a high-visibility red and yellow handle that is padlockable in the OFF position. This allows for secure Lockout/Tagout procedures, preventing the system from being re-energized while work is in progress. The "knife-edge" contact mechanism ensures rapid switching and superior arc suppression, which is essential for the high currents found in large factory plants, massive HVAC systems, and commercial solar installations.

Frequently Asked Questions
Q: Can this handle a 30kW motor?
A: Yes. The IS11C is specifically rated to handle 30kW at 415V for motor (AC23) loads, making it an excellent choice for large industrial pumps, fans, and compressors.
Q: Is the enclosure large enough for thick 25mm² cables?
A: Yes. The IS11C uses a significantly larger enclosure (240mm x 160mm) than the lower-amperage models. This provides the necessary "bend space" and terminal clearance required for the heavy cables used in 80A circuits.
Q: Does it have a neutral link included?
A: This is a true 4-pole isolator, meaning the neutral is switched simultaneously with the three phases. This provides complete electrical isolation of the load from the supply, which is often required in specific industrial safety standards to ensure the neutral is also disconnected.
Who can install this?
Installation must be carried out by a qualified industrial electrician. Managing an 80A supply requires working with heavy-gauge cables (up to 25mm²). Correct terminal torque is vital; at 80A, even a slight resistance due to a loose connection can lead to rapid heat buildup and catastrophic electrical failure. The installer must also ensure that heavy-duty cable glands are used to maintain the IP66 environmental seal.
What is this for?
The IMO IS11C is the industry standard for High-Amperage Safety Isolation:
- Industrial Plant Machinery: Main isolation for large production lines, heavy-duty metal presses, and industrial shredders.
- Massive HVAC Units: Acting as the local disconnect for large-scale commercial chillers and complex air handling systems.
- Commercial Solar PV: Serving as the AC side isolator for high-capacity solar inverters before they connect to the main building distribution.
- Water Treatment & Pumping: Providing a weatherproof disconnect point for high-power pumping stations and treatment facility equipment.
