Suntree AC Surge Protective Device (SPD) / OVR 40kA 550VDC 2 Pole

The Suntree AC Surge Protective Device (SPD) / OVR 40kA 550VDC 2 Pole is a high-performance surge protection solution designed to safeguard solar photovoltaic (PV) systems and DC electrical installations from transient overvoltage caused by lightning strikes and switching surges. Engineered for reliability and long-term performance, this surge protective device helps prevent costly damage to sensitive electrical equipment while improving overall system safety.

With a maximum surge current capacity of 40kA, a 550V DC voltage rating, and a 2-pole configuration, this SPD delivers comprehensive protection for both positive and negative DC conductors. Its rapid response time ensures excess surge energy is safely diverted before it can damage inverters, charge controllers, batteries, combiner boxes, or other connected equipment.

Manufactured using high-quality components and designed for DIN rail mounting, the Suntree OVR 40kA SPD is easy to install and suitable for residential, commercial, and industrial solar power systems.
