Power & Protection: A Sparky's Guide to Electrical Switchgear

The switchboard is the command centre of any electrical installation. The components inside—the switchgear—are what provide the critical, life-saving protection against overloads, short circuits, and electric shock. For any professional sparky, choosing high-quality, compliant switchgear is the most important part of ensuring a safe and reliable job.

At SCHNAP, our comprehensive Switchgear range is designed to keep your projects powered, protected, and compliant with Australian standards, whether it’s a residential fit-out, a commercial install, or a large-scale industrial job.

Core Circuit Protection: RCBOs & MCBs

These are the workhorses of any modern switchboard.

• MCBs (Miniature Circuit Breakers): Your first line of defence for a circuit. An MCB provides essential protection against overcurrent (overload) and short circuits. We stock a huge range of breaking capacities and trip types (like C-curve for general purpose loads) to suit any application.
• RCBOs (Residual Current Circuit Breakers with Overload): The all-in-one safety solution and the modern standard for final sub-circuits in Australia. An RCBO combines the full function of an MCB with a life-saving RCD (safety switch), providing protection against overcurrent, short circuits, AND earth leakage.

Switching & Control Gear

Beyond simple protection, we have all the gear for controlling your circuits.

• Main Switches: The primary isolation point for the entire installation, allowing you to safely de-energise the board.
• Contactors: Think of these as a heavy-duty, remote-controlled switch. A contactor is perfect for switching large loads like motors, commercial lighting circuits, or HVAC systems, and can be controlled by a timer, sensor, or smart system.
• Thermal Overloads: The specific protection required for motors. A thermal overload is designed to trip if a motor is working too hard and drawing too much current, preventing it from burning out.

Metering & Other Essentials

Our switchgear range also includes all the other DIN-rail-mounted essentials you need:

• Surge Protectors: To protect the entire installation from damaging voltage spikes from lightning or the grid.
• Kilowatt Hour (kWh) Meters: For sub-metering and accurately monitoring energy usage on specific circuits or in different tenancies.
