Switching operations are far and away the most common cause of overvoltages. Type 2 surge protective devices provide effective protection against these dynamic disturbance variables. Whether in an industrial environment or in a residential building, type 2 protection ensures basic protection for your installations and devices.

Your advantages

  • Low voltage protection level with varistor-based protective circuit
  • Powerful disconnect device provides optimum protection against overvoltages
  • High short-circuit current rating up to 50 kA
  • Usage up to 315 A without a backup fuse saves time, money, and space
  • Universally pluggable protective devices enable ease of maintenance

The narrowest type 2 surge protective device in the world

Type 2 surge protection  

Type 2 surge protection in the subdistribution

With an overall width of just 12 mm per channel, VALVETRAB SEC is the narrowest type 2 surge protective device in the world. With an overall width of just 48 mm, you are able to implement excellent protection against overvoltages in a five-conductor system.

The protective device offers a voltage protection level of 1.5 kV. This means it meets the requirements of type 3 device protection. VALVETRAB SEC limits voltage peaks to such an extent that machines, systems, and household appliances are not damaged.

For industry and building installations with an external lightning protection system, type 2 surge protection is the second level of protection after the type 1 lightning arresters. The surge protective device handles short-circuit currents up to 50 kA. You can use the type 2 protective device without a backup fuse up to a main fuse nominal current of 315 A.

The world’s first type 2 Push-in surge protection

Type 2 Push-in surge protection  

Type 2 Push-in surge protection

The VAL-MS-PT is the first type 2 surge protective device in the world with Push-in connection technology. This connection method is already widely used in electrical engineering applications. Now you can also benefit from the easy handling during installation with surge protective devices as well. The Push-in connection technology allows tool-free installation, and it also means there is no need to check the recommended nominal torque.
The option of through-wiring also enables further savings, because no additional installation material is necessary.
Use the optional remote indication contact, which is also easy to install with through-wiring, to ensure that the protective devices are monitored.

Modular and pluggable

VALVETRAB MS  

VALVETRAB MS with ready-to-install arrester blocks

VALVETRAB MS devices are type 2 surge protective devices with a modular design. They consist of a base element and a protective plug. The overall width per path is 17.5 mm, which corresponds to one unit of horizontal pitch (HP).We make the choice easy for you with ready-to-install arrester blocks for various applications.

  • Ready-to-install arrester blocks combine various applications.
  • Biconnect terminal blocks enable easy bridging, e.g. for residual-current devices.
  • Mechanical coding upon inserting the protective plug into the base element for the first time.
  • Easy and impedance-neutral insertion and removal, e.g., for insulation measurements. There is no need for complicated disconnection and connection. 

Backup fuse included

Surge protection for 5-conductor networks  

Surge protection with coordinated backup fuse

If the main fuse in your application is > 315 A, you also have to provide surge protection with an additional fuse. In this case, we offer suitable surge protection in the form of the VAL-CP-MCB, consisting of a type 2 surge protective device with coordinated arrester backup fuse.

This means you get double the safety with minimal installation effort. Enjoy the benefits of easy planning, regardless of the installation environment. The integrated status indicator and option for remote signaling provide information regarding the effectiveness of the surge protection. The space-saving solution is available for 5-, 4-, and 3-conductor systems. 

Type 2 surge protection for 60 mm rail systems

VALVETRAB combination  

Surge protection with backup fuse for 60 mm rail systems

VAL-CP-MOSO are type 2 universal surge protective devices with a high short-circuit current rating on a narrow mounting base of just 54 mm.

These surge protective devices also feature a status indicator and remote indication contact.

You can install the protective devices in all common 60 mm rail systems.

This type of installation is incredibly easy: Snap on the surge protection, connect the equipotential bonding and you’re done!
