Overview

Voltage surges caused by lightning, grid switching, or equipment faults can severely damage electrical infrastructure. Chadwick’s SPD Enclosures provide a purpose-built housing for surge protection devices — keeping your systems operational and protected in the most demanding environments.

Engineered with durability and safety in mind, our SPD Enclosures are available in both wall-mounted and modular formats. Each unit is designed for effective thermal management, accessibility, and compliance with relevant Australian Standards.

Whether integrated into a larger switchboard system or used as a standalone protection unit, our enclosures ensure your assets — from data centres to industrial machinery — remain protected from harmful transients.

FAQs

How long does it take to manufacture a switchboard?

Lead times vary depending on the complexity of your board and current production capacity. Standard boards can be completed in 2–4 weeks, while fully custom solutions may take 6–8 weeks. For urgent requirements, speak with our team — we’ll do our best to accommodate your timeline.

Do you offer site inspections or on-site switchboard modifications?

Yes. Our technicians regularly attend shutdowns and site visits for maintenance, upgrades, or compliance modifications. We also offer thermal imaging and grading studies as part of our service options.

Can Chadwick supply switchboards for projects outside NSW?

Absolutely. We supply to VIC, QLD, ACT, and other regions nationally. Freight, crating, and delivery options can be discussed during quoting to ensure safe and timely arrival.

Are your switchboards built to Australian standards?

Yes — our boards are engineered in alignment with AS/NZS 61439 standards and built in accordance with NESMA best practices. If you require project-specific compliance documentation, we’re happy to provide it.

Do you offer spare parts or support for non-Chadwick boards?

We do. Our team can help source or recommend compatible components and provide alternatives if your original parts are obsolete or discontinued.

Can I send through drawings or specs for a custom quote?

Yes — we encourage it. You can upload drawings directly through our quote request form or email them to [email protected]. Our estimators will get back to you promptly.
