Shop surge arrestors and surge protection devices to guard switchboards and sensitive equipment against transient voltage spikes from lightning, switching events and grid fluctuations. Trusted by electrical contractors Australia-wide.
NAW Controls’ Surge Protection range guards electrical installations against transient voltage spikes caused by lightning strikes, switching events, grid fluctuations and internal faults. Left unprotected, these spikes can damage sensitive electronics, industrial automation equipment and control systems, leading to costly downtime and equipment replacement.
Surge arrestors are typically installed at the main switchboard, and in some cases at sub-boards protecting particularly sensitive equipment, providing layered protection through the installation. Our range is selected for reliable clamping performance and compliance with relevant Australian standards, making it a practical addition to any new or upgraded switchboard.
Yes, RCDs and MCBs protect against earth leakage, overload and short-circuit faults, but not transient voltage spikes. Surge protection is a separate, complementary layer for sensitive equipment.
Surge arrestors are typically installed at the main switchboard, with additional units at sub-boards protecting particularly sensitive equipment for layered protection.
Surges can be caused by lightning strikes (direct or nearby), switching of large loads, grid fluctuations, and internal faults within a facility’s own electrical system.
How do I know if my surge arrestor needs replacing?
Most surge arrestors include a visual indicator showing whether they’ve absorbed a surge event and need replacement; check your specific product’s indicator after any significant surge.
Can surge protection be retrofitted to an existing switchboard?
In most cases yes, provided there’s suitable space and DIN rail mounting available; our team can help confirm compatibility with your existing board.
