IMO IS06C 40A 4-Pole Enclosed Rotary Isolator – IP66 Rated AC Disconnect Switch

This is the IMO IS06C 40A 4-Pole Enclosed Rotary Isolator – an IP66 Rated AC Disconnect Switch   available at SparksDirect for the best price. Purchase this item with confidence at Sparks today.

The IMO IS06C is a high-visibility, surface-mounted rotary isolator designed to provide a secure and reliable means of electrical disconnection. Rated at 40A, it is capable of isolating three-phase loads along with the neutral, making it a critical safety component for industrial machinery, HVAC units, and large motor installations. The switch is housed in a high-impact, flame-retardant enclosure that carries an IP66 rating, ensuring the unit remains completely dust-tight and resistant to powerful water jets.

For maximum safety, the handle features a padlockable "OFF" position, which allows technicians to lock the switch during maintenance to prevent accidental re-energization (Lockout/Tagout). The IS06C utilizes a "knife-edge" contact design that ensures efficient arc suppression and long-term electrical reliability. It is a standard choice for commercial kitchens, factory floors, and outdoor air conditioning units as a primary AC disconnect point.

Frequently Asked Questions

Q: Can this be used for a 230V single-phase supply?

A: Yes. Although it has 4 poles for three-phase systems, you can use two of the poles to isolate a single-phase Live and Neutral. This provides a full physical break of the circuit for safety.

Q: What is the difference between an isolator and a circuit breaker?

A: A circuit breaker is designed to trip automatically during a fault. An isolator like the IS06C is a manual switch. It does not provide overcurrent protection; its sole purpose is to provide a guaranteed physical disconnection so work can be performed safely.

Q: Does it have knockouts for cable entry?

A: Yes, the enclosure features standard M25 threaded knockouts. To maintain the IP66 rating, you must use appropriately rated M25 cable glands when bringing cables into the box.

Who can install this?

Installation must be carried out by a qualified electrician. Because an isolator is a primary safety device, it must be wired correctly to ensure all phases are broken simultaneously. The installer is responsible for ensuring the cable entries remain watertight and that the unit is positioned in an accessible location for emergency use.

What is this for?

The IMO IS06C is used for Manual Safety Disconnection:

• Local Machinery Isolation: Positioned near industrial lathes, conveyors, or pumps to allow for instant power cutoff during repairs.
• HVAC Maintenance: Used as the external disconnect switch for air conditioning condensers and large ventilation fans.
• Commercial Kitchens: Providing a waterproof means of isolating heavy appliances like industrial fryers or dishwashers for cleaning.
• Outdoor Installations: Frequently used as an AC isolator for solar PV inverters or outdoor pumping stations due to its high weather resistance.
