What Is an Isolation Switch?

An isolation switch, also known as a disconnector or isolator, is a critical safety device in electrical systems. It ensures a circuit is completely de-energized for maintenance, repairs, or emergencies by physically disconnecting power flow. Unlike standard circuit breakers, isolation switches provide a visible break in the circuit, guaranteeing no residual current remains. At Sfere, our meter isolation switch is engineered for reliability, safety, and compliance with international standards.

What Is the Purpose of an Isolator Switch?

The primary purpose of an isolator switch is to enhance electrical safety. It allows technicians to:

Safely shut off power to specific circuits or equipment.

Perform maintenance without risking electric shock or equipment damage.

Comply with safety regulations during installations or upgrades.

In applications like meter boxes or industrial systems, isolators like the MTS Isolation Switch SFG ensure seamless disconnection, protecting both personnel and infrastructure.

What Does an Isolation Switch Do?

An isolation switch acts as a fail-safe barrier between electrical components and their power source. Key functions include:

Complete Circuit Isolation: Creates a physical gap to prevent accidental re-energization.

Overload Protection: Works alongside circuit breakers to safeguard against surges.

Versatility: Suitable for residential, commercial, and industrial setups.

For example, Sfere’s MTS model is designed for smart meter systems, ensuring compliance with modern grid requirements.

Who Installs Meter Isolators?

Certified electricians or utility professionals typically install meter isolators. This ensures:

Compliance with local electrical codes.

Proper integration with existing meter boxes or distribution boards.

Safe handling of high-voltage components.

At Sfere, we recommend partnering with licensed experts for installing our MTS Isolation Switch SFG to guarantee optimal performance and safety.

Installation of New Smart Meter and Meter Isolator

Modern smart meter installations often require a meter isolator for enhanced safety and convenience. Here’s how the process works:

Power Disconnection: A certified technician shuts off the main supply.

Isolator Mounting: The MTS Isolation Switch SFG is installed between the meter and main panel.

Smart Meter Integration: The isolator allows easy meter replacement without disrupting the entire system.

Testing: The system is re-energized and tested for safety.

Sfere’s isolators are designed for quick, tool-free installation, reducing downtime and labor costs.
