Isolator switches are essential safety devices used to disconnect electrical circuits during maintenance, installation, or emergency shutdowns. Available in both 1-phase and 3-phase versions, they provide reliable power isolation for residential, commercial, and industrial applications.
The 1-phase isolator is commonly used for household and light-duty equipment such as air conditioners, small pumps, water heaters, and lighting circuits. A compact 2-pole design is rated for 220–240V. Its smaller size makes it ideal for outdoor AC compressors and general home installations.
The 3-phase isolator is built for heavy-duty performance, designed to safely disconnect large pumps, industrial machinery, commercial HVAC systems, and equipment operating on 380–415V. With a 4-pole configuration, it offers greater capacity, higher amperage ratings, and increased mechanical durability for demanding environments.
Both types feature weatherproof enclosures, rotary ON/OFF operation, and lockable safety mechanisms, ensuring safe isolation even in outdoor or harsh conditions. Easy to install and built for long-term use, these isolators provide dependable power control and protection for any electrical system — from homes to industrial facilities.
