Type 3 surge protective devices with screw and push-in connection technology

Type 3 surge protection

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.

Your advantages

  • Powerful protection for AC and DC applications enables use in a variety of applications
  • Disconnect device provides increased safety in the event of electrical and thermal overload
  • Information concerning the status of the protective device is always available by means of visual and mechanical status indicator and remote indication contact
  • Pluggable protective devices enable easy maintenance

Type 3 end device protection for installation in cable ducts or underfloor systems

Surge protection as type 3 device protection for installation in cable ducts or underfloor systems

Type 3 device protection for cable ducts or underfloor systems BLOCKTRAB

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:

  • Concealed surge protection with installation in device sockets or flush-mounted sockets
  • Can be installed directly using preassembled and color-coded cables
  • Audible signal in the event of overload
  • The compact design enables universal use

Intermediate plug with type 3 surge protection for the socket

Type 3 end device protection for sockets as an intermediate plug

Type 3 device protection as an intermediate plug MAINTRAB

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.

  • Easy retrofitting in existing installations
  • Safe disconnect device
  • Necessary accessories are included
  • Country-specific versions available
