Type 3 surge protection completes the protection concept. As device protection, it limits the last remaining pulses which could cause damage to the building installation or system. Type 3 SPDs are installed directly upstream of the end device. This way, they even protect sensitive end devices, such as servers, controllers, or power supply units.

Surge protection as type 3 device protection for installation in cable ducts or underfloor systems
The BLOCKTRAB product family protects your end devices, concealed in cable ducts or underfloor systems, against surge voltages. A DIN-rail-mountable product is not always the right solution. The BLT-T3 is installed in device sockets, cable ducts, and underfloor systems. The BLT-SKT is installed on the rear of standard sockets. The connected loads remain in operation even in the event of an overload:
Narrow type 3 surge protection for protecting 24 V power supplies
Protect the 24 V power supply of end devices such as I/Os or controllers with our narrowest type 3 surge protection solution. Just 6 mm wide, the narrow design ensures space-saving installation. Our pluggable protection modules enable easy testing and replacement.
Type 3 end device protection for sockets as an intermediate plug
The adapters for mains sockets are ideal for retrofitting surge protection upstream of electronic end devices. A green LED indicates the surge protection function of the protective device. Optimum protection is provided for all connected loads. By plugging the surge protection in before the socket strip, all connected end devices will be protected against surge voltages.
The intermediate plug with interface protection simultaneously protects the power supply and another interface against surge voltages.
