BLITZDUCTOR® VT

Lightning Current / Surge Arrester

Compact DIN rail mounted surge protective device with screw terminals for multi-core lines.
  • Cost-effective protection of multi-core signal lines
  • Interface-specific versions, e.g. RS485 or telecommunication systems
  • Versions for d.c. power supply systems

Description

BLITZDUCTOR VT is a family of compact DIN rail mounted arresters and consists of different types of enclosures with different connection methods. Both devices for protecting four-wire signal interfaces with screw connections, but also devices for protecting terminal equipment of telecommunication systems as well as telephone systems with RJ connection are for example available. All types can be mounted on DIN rails and are earthed via a screw terminal.

Different types of BLITZDUCTOR VT arresters are available depending on the application.

Detail 1

BVT enclosure type with a width of 1.5 modules and screw terminals:
BVT AV/LD: Two protected lines for d.c. power supply systems

Detail 2

BVT enclosure type with a width of 3 modules and screw terminals:
BVT RS485 specifically designed for protecting RS485 / RS422 interfaces.

Detail 3

BVT enclosure type with a width of 1.5 modules and RJ connection:
BVT TC1 for protecting telecommunication interfaces.

Detail 4

Separate earth connection on the unprotected side of the device. The second slot of the double terminal is intended for connecting the terminal equipment to the equipotential bonding.

Owing to the additional decoupling resistors at the output, even diodes with a low absorption capacity integrated in terminal equipment are energy-coordinated with the protection stages. This is especially important for optocoupler interfaces.

BVT TC

Basic circuit diagram BVT TC
Dimension drawing BVT TC

Energy-coordinated and leakage-current-free surge arrester for a/b lines, ISDN Uk0 or ADSL with RJ45 connections and additional screw terminals. Pinning of the RJ45 sockets is compatible with RJ11/12. The parallel screw terminals are more robust than the RJ45 sockets and increase the total nominal discharge current to 10 kA.
