AC Isolator switches are devices or systems that isolate a particular circuit for maintenance and prevent currents from passing through. The main isolator switch, also known as an isolator, typically consists of two sets (or one set) of electrical contacts mounted in series. The line side is connected to a power supply outside the building.
Product Benefits
What are the Different Types of Electrical Isolator Switches?
01 Add-on Auxiliary Contacts
The isolating switch adopts the same auxiliary contact, and the auxiliary contact and the main pole of the switch act at the same time. A normally open contact with pre-disconnect function can be provided as required.
The isolation switch can be installed with up to four auxiliary accessories (2 on the right, 2 on the left)
02 Terminal shrouds
The isolation switch terminal shroud has a simple appearance design, high-quality transparent PC material, flame-retardant, high strength, no color change after long-term use, high-quality waterproof and easy to install.
03 Side Mount Add-on Fourth Pole
Simultaneous or early contact operation of the fourth pole with respect to the switch disconnector poles.
04 Switch body
Onccy switch adopts compression contact opening and closing technology, and has the function of complete disconnection indication. It is an isolator,a
breaker or a switch, and with inlerlock mechanism, it can be to an exchage switch.
