## Summary description

pro tec BY1-B+C/3 FW10 is a PV surge protector rated for 1000V DC with combined T1+T2 protection (B+C) providing 20/40kA discharge capability. Designed for photovoltaic arrays, it protects inverters and DC conductors from lightning-induced and switching overvoltages. Intended for rooftop and ground-mounted solar installations as part of PV system surge protection.

## Long description

pro tec BY1-B+C/3 FW10 1000V DC is a surge protector designed for photovoltaic systems. It provides combined T1+T2 (B+C) protection with a rated voltage of 1000 V DC and discharge capability specified as 20/40 kA, intended to reduce the impact of lightning-induced and switching overvoltages on inverters, combiner boxes and DC conductors in rooftop and ground-mounted solar arrays.
Advantages
This surge protector offers coordinated two-stage protection (type 1 + type 2) in a single device, enabling effective handling of both high-energy lightning currents and lower-energy switching surges. The device is compact and built for PV applications, allowing direct installation near the array or inverter DC input. Its 1000 V DC rating makes it suitable for modern high-voltage string configurations, and the defined discharge capability provides measurable protection performance against transient overvoltages.
Suitable for
Protection of photovoltaic inverters and DC combiner boxes
Rooftop solar installations and ground-mounted PV arrays
New PV systems with string voltages up to 1000 V DC
Systems requiring coordinated T1+T2 surge protection for lightning-prone areas
Key specifications
Rated voltage: 1000 V DC
Protection class: combined T1+T2 (B+C)
Discharge capability: 20/40 kA (specified impulse discharge levels)
Application: photovoltaic DC side protection
Mounting location: near inverter DC input or combiner box
How to use
Install the surge protector in the PV system’s DC circuit according to national electrical codes and the inverter manufacturer’s recommendations. Mount the device close to the inverter DC terminals or inside the combiner box to minimise conductor length between the array and the protector. Ensure secure connections to the positive, negative and protective earth conductors as required for combined T1+T2 devices. Verify correct polarity and proper earthing before energising the system. Periodically inspect the unit for signs of damage or operation indicators following extreme events.
Usage recommendations
Use this device as part of a coordinated PV surge protection concept: pair it with appropriate DC fusing, correct cable routing and separate AC-side protection to achieve comprehensive system protection. Replace or service the protector after a significant surge event according to local safety rules and manufacturer instructions.
