Isolator Switches

Isolator Switches

Electrical safety relies heavily on isolation switches. In addition to protecting equipment from electrical problems, they also make it possible to safely examine electrical circuits and prevent maintenance-related electrical shocks.

Uses of Isolation Switches

Isolator switches are widely used in renewable energy systems, business and industrial buildings, and residential locations, and you can buy them from us at market-competitive pricing. You should consider your needs, the environment, the specifications, and the advice of experts before buying an isolator switch. Because, these isolator switches are available in a variety of ranges. You can get isolation switch that have Sparkelec 1/2 Pole 35amp Isolator Switch IP66, Sparkelec 3 Pole 35amp Isolator Switch IP66, or Sparkelec 4 Pole 63amp Isolator Switch IP66, or you can get an isolator that has three phases.

Installation Tips for Isolator Switches

• To start setting up isolator switch correctly, read the instructions thoroughly.
• Utilizing the appropriate apparatus will protect you from any potential harm or errors that may occur during the installation process.
• Among the many precautions you should take to stay safe are disabling any power sources and wearing protective gear.          
• Lastly, after installation is complete, test your installed switch to ensure it is fully functional and secure.

FAQ

What is an isolator (disconnector) switch used for? 

It provides a visible, physical break in an electrical circuit, enabling safe maintenance by ensuring no current flows to the isolated area.  

What types of isolator switches are available? 

Common types include single-pole, double-pole, triple-pole, load-break, rotary, and DC-specific isolators each suited to different systems and phase requirements.

Can isolator switches break the circuit under load? 

No they are off-load devices, designed to isolate circuits only after load has been cleared by a circuit breaker or other protection.  

Are isolator switches necessary for safety compliance? 

Absolutely they support lockout/tagout procedures, prevent accidental re-energization, and are essential for safe maintenance in industrial settings.

What special isolators are used for DC or solar applications? 

For PV systems, True DC isolators provide fast, arc-reducing disconnection and comply with UL508I standards for safe DC switching.
