An ac isolator（Disconnector）, also known as an ac disconnect switch, is an electrical safety device that allows you to quickly and safely cut off the power supply to a specific circuit or piece of equipment. It prevents any electrical faults or accidents during maintenance or inspection work. In simple terms, it’s a switch that you can use to turn off the power when needed.
For outdoor ac isolators, the IP66 rating is essential because it ensures that the device can withstand harsh environmental conditions such as heavy rain, snow, and dust. This rating guarantees that your isolator will remain safe and functional, even in extreme weather conditions, providing you with reliable protection and peace of mind.
When selecting an IP66 outdoor isolation switch, the amp rating must be matched to the electrical load. Common amp ratings are 30, 60, 100 and 200A. The switch amp rating should meet or slightly exceed the rating of the circuit breaker supplying the AC unit. A properly sized switch will safely handle the starting current and running loads of the outdoor AC condenser. It’s advisable to consult an electrician to ensure the switch amp capacity matches your specific AC equipment.
IP66 rated AC isolation switches feature an external handle that allows the power to be safely turned on or off. This allows the AC system to be isolated for routine maintenance or repairs. The power on/off positions are clearly labeled or have visual indicators. Some models have provisions for padlocking the switch in the off position when necessary.

A: Yes, you can use an IP66 AC isolator indoors. It provides additional protection against dust and water, which may be beneficial in certain indoor environments, such as industrial settings or areas with high humidity.
A: It’s recommended to inspect your IP66 ac isolator at least once a year or more frequently, depending on your specific application and environmental conditions. Regular inspections can help identify any potential issues and ensure that the isolator is functioning correctly.
A: While IP66 is a common rating for outdoor AC isolators, other IP ratings may also be suitable depending on the level of protection required. For example, IP67 offers protection against temporary immersion in water, while IP68 provides protection against continuous submersion.
A: No, IP66 ac isolators are specifically designed for use with ac circuits. If you require an isolator for a DC circuit, you should look for a suitable isolator with the necessary protection rating.
A: An isolator is a manually operated switch that disconnects the power supply for maintenance or safety purposes, while a circuit breaker is an automatic safety device that trips and disconnects the power supply when it detects an electrical fault or an overcurrent condition. Both devices serve different purposes but work together to ensure the safety of electrical circuits and equipment.
