4 FAQs about Main breaker switch for sale in Melbourne

What is a main switch?

Main switches are electrical isolator devices that disconnect entire installations or circuits from power supply. Available in 80A-100A ratings with single-pole, double-pole, or three-pole configurations, they enable safe maintenance isolation, emergency disconnection, and comply with AS/NZS 3000:2018 Australian standards.

What is the difference between a main switch and a circuit breaker?

A main switch (or isolator) is designed purely to switch power on and off manually—it does not provide overcurrent protection. A circuit breaker automatically trips during overload or fault conditions to protect circuits. Main switches are used for isolation during maintenance and servicing, allowing electricians to safely de-energise circuits.

Where can a load-break switch be used?

Load-break switches can be used anywhere where compact ON-OFF switches with large contact gaps (isolators), high contact pressure, and greater short circuit protection is required.
