Is your Surge Protection Device (SPD) coordination still relying on legacy Over Current Protection Device (OCPD)?
Standard surge protection is not enough if the disconnection fails. That was the focus of the NOVARIS Surge Protection Masterclasses we hosted in Singapore and Johor Bahru late last year. These sessions were not just theory refreshers. They were designed for consultants, switchboard builders, and engineers who need surge protection that performs reliably in the field, not just on paper.
During the two masterclasses, we explored the key factors that define SPD reliability, including:
- Why SPD-specific disconnectors are replacing traditional OCPDs. Safer, more predictable coordination in practice.
- Installation pitfalls that compromise protection. Real-world case studies show how even advanced SPDs can fail when installation practices are ignored.
- What is next for the industry. A first look at the upcoming IEC 61643-06 standard for SPD-specific disconnectors.
The key takeaway is simple: reliability is a design choice. The right SPD is only part of the equation. How it is coordinated, protected, and installed determines whether it will perform when the system is under stress.
If your coordination strategy still relies on traditional OCPDs, it is worth reviewing whether your protection approach is keeping up with current best practice.
For engineers wanting to explore the technical side, including coordination behaviour, safer disconnection, and why SPD-specific devices are becoming the preferred approach, you can access the product documentation below.
