  • Low voltage protection level, capable of protecting terminal equipment
  • Arrester consists of a protection module and a base part
  • Easy replacement of protection modules
  • All protection components integrated in the protection module
  • Two universal base parts with or without signal disconnection
  • Functional and appealing design
  • DIN rail mounted device with integrated earthing
  • Minimum space requirements, four single lines or two pairs over a width 12 mm
  • Vibration and shock-tested for safe operation

Description

BLITZDUCTOR SP arresters are pluggable and universal multipole DIN rail mounted surge arresters for protecting measuring and control circuits, bus systems, emergency alarm systems or telecommunication systems.
BLITZDUCTOR SP arresters combine a permanently high impulse current discharge capacity with an extremely low voltage protection level, thus ensuring effective protection of terminal equipment even in case of interference caused by impulse currents and surges resulting from switching operations.

The arresters provide protection against vibration effects and shock up to a 30-fold acceleration of gravity. The function-optimised arrester design ensures both fast and easy replacement of protection modules which house all relevant protection elements.
A wide range of accessories e.g. for earthing unused lines or easily testing lines round off the product range.
The protection module and base part have to be ordered separately!

Detail 1

Two-part design comprising a base part and a protection module.

Detail 2

The module locking mechanism ensures that the module is vibration-proof and protected against polarity reversal.

Detail 3

All protection elements are integrated in the plug-in module.

Detail 4

Two universal base parts with or without signal disconnection if the protection module is removed.
