ProTec T2-PV 5Y
The Raycap ProTec T2-PV 5Y is a pluggable EN Type 2 / Type 1CA PV surge protection device, developed for 1100 V DC photovoltaic systems and designed for DIN rail mounting. It can protect two or three PV strings in a single housing, making it an ideal solution for string combiner boxes and PV inverters.
The ProTec T2-PV 5Y consists of high-performance, pluggable, DIN rail-mountable protection devices designed for 1100 V DC photovoltaic systems. It features EN Type 2 and Type 1CA PV SPD classification.
Type 2 protection does not carry direct lightning current; it reduces induced and switching overvoltages to a level the device can withstand. This is the most common protection class in PV installations where no external lightning protection is present or the risk of direct strike is low.
The distinguishing feature of the series is its "5Y" structure: the device is configured to protect two or three PV strings in a single housing. Instead of using separate surge arresters for each string in combiner boxes, multi-string protection is achieved with a single device—significantly reducing panel module width and wiring complexity.
All devices feature low-profile modules, ensuring no installation issues in shallow combiner boxes. Two different terminal connection options are offered, facilitating adaptation to existing panel designs.
Vibration and shock resistance are suitable for the mechanical conditions of ground-mounted PV sites. A precise and reliable remote contact allows monitoring of the surge arrester's status via SCADA—eliminating the need for on-site inspection in geographically dispersed installations.
