Santon switchgear is used within several worldwide markets including industry, railway transport, maritime and offshore, machine building, the energy sector, defense and of course, the solar market.

Proven, trusted and reliable

Santon is at the forefront of technology specifically developed for the renewable energy market and in particular solar energy. Meeting the demands of safe and efficient DC switching you can be sure that Santon products have been developed to meet the highest technical and commercial standards.

Our range of X type switches have become the safety component of choice for many of the largest solar inverter manufacturers whilst the firefighter safety switch is an innovative solar panel shutdown solution that is compatible with all standard string inverters.

The Santon DC switch

The expectations of the DC switch are increasing: 

• DC disconnect switch is a human safety device, it needs to effectively operate under load when needed to keep operator safe.

• Besides static reliability, DC disconnecting can easily create arc – fire risk.

• As a safety device, It must work for minimum 20 years throughout the lifetime of the inverter without problem.

Safety first

We realize our clients are not the only ones who depend on the safety of our switchgear. Our clients’ clients do too. Whether our switches are used by an OEM for building an inverter or by an installer installing a solar plant, the safety and profitability of our clients partly rely on the quality of our switchgear and they therefore need our switches to be the best available. Working with high automation, skilled people and being NEN-EN-ISO 9001:2015 and IRIS ISO/TS 22163:2017 certified, guarantees our clients the best products they can buy. Internal audits are being held on a regular basis by ourselves, external auditors and our clients.

Market and customer specific solutions

Lead times should be as short as possible because of the unpredictable and fast growing demands for PV installations. Once demand exists, we have to be able to deliver fast. The modular design of our switches and our automatic production lines make sure we are able to meet this demand.

Although we have automatic production lines for mass production and a complete series of standard solutions, our clients often present us with very specific demands. This is what Santon does best and what we have always done best: working together with our clients to develop the best solution for their needs.

Customer specific demand can vary from a specific assembly of existing materials, but can also involve developing a special knob or mechanism. We are able to provide our clients with a very complete service and act as a true partner, with a team of engineers, designers and technicians.

The Santon Firefighter Safety Switch

The sun provides your energy, santon provides your safety. In most photovoltaic systems, the dc isolator is integrated into the dc/ac power inverter. After switching off the dc isolator, the cables between the dc solar modules and dc/ac power inverter running through the building are still subject to up to 1000 v dc. in the event of a fire, firefighters are exposed to a very serious source of potential danger. The santon firefighter safety switch (dfs) provides the solution. It directly disconnects the dc current in close proximity to the solar modules and creates a safer situation for firefighters.

• AC power shut down = automatic DC power shut down 

• Auto reset when AC power is back = DC power is back

• Easy to install for small to large, existing and new installations

• Based on the world’s most used DC switch from Santon
