Description:

The Phoenix Contact VAL-MS 1000DC from the VALVETRAB series is a modular Type 2 Surge Protective Device (SPD) designed for DC applications up to 1000 V, making it ideal for photovoltaic systems and industrial DC installations.

Manufactured by Phoenix Contact, this surge arrester provides reliable protection for inverters, PV strings, and sensitive electronic components against transient overvoltages caused by indirect lightning strikes, atmospheric disturbances, and switching events.

Configured in L+ / PE / L− topology, it ensures full pole protection for DC systems. The device features plug-in replaceable protection modules with integrated visual status indicators and is designed for quick installation on a DIN rail inside electrical panels or combiner boxes.

🛠 Warranty: 12 months by Green Energy

⚡ Operating Principle:

When a transient overvoltage occurs:

• The SPD intercepts the voltage spike.

• Excess energy is safely diverted to earth (PE).

• Residual voltage is limited to safe levels.

• Downstream equipment remains protected.
