ProBloc T1SG

The Raycap ProBloc T1SG is a VDE-certified Type 1+2+3 Surge Protective Device (SPD). Since it does not generate leakage current, it can be installed in the pre-meter area; it is designed for protecting sensitive electronics near building entry points, such as smart meters and electric vehicle charging systems. Available with 7.5 kA and 12.5 kA lightning current options.

The ProBloc T1SG is a VDE-certified Type 1+2+3 surge protective device. By combining three protection types in a single unit, it ensures the protection of sensitive electronic equipment located near the building's entry point. Smart metering systems and electric vehicle charging applications are key areas where the product excels.

The most distinctive feature of the device is that it does not generate leakage current. This allows it to be installed in the pre-meter area and meet the installation requirements for this space. Pre-meter installation means that any surge entering the facility is limited before it reaches the meter and all subsequent equipment.

ProBloc T1SG features universal energy coordination, ensuring compatible operation with any equipment located downstream. Thanks to its low let-through energy value, equipment in close proximity to the device remains protected under all conditions. The series includes two versions with 7.5 kA and 12.5 kA lightning current withstand capabilities.

ProBloc T1SG is preferred in applications requiring protection for sensitive equipment near the building entry point:

Smart metering systems — Protection of meters and communication modules
Electric vehicle charging stations — Surge protection for charging unit electronics
Pre-meter installation points — Suitable due to no leakage current generation
Residential and complex electrical entries — Building entry panel protection
Commercial building entries — Where compact, single-device solutions are needed
Small-scale facilities — Three types of protection with a single device instead of staged protection
Renovation projects — Adding protection to existing entry panels
