Product catalog summary
Introduction
The document discusses the advantages and features of the new range of line reactors by BLOCK Transformatoren-Elektronik GmbH, a company specializing in transformers, power supplies, EMC filters, and reactors.

Advantages of the New Range
  • Robust terminals supporting up to 250A or flat copper connections.
  • Resource-saving use of materials and compact design.
  • Integrated lifting rings and multifunctional fixing rails.

Features of Line Reactors
  • Minimizes system reactions such as harmonics.
  • Reduces charging currents in the DC link capacitor, increasing the service life of frequency converters.
  • Improves reactive-power components and cos(phi).
  • Fast assembly and small footprint, matched to Rittal's system dimensions.

Company Overview
BLOCK Transformatoren-Elektronik GmbH, founded in 1939, is a family-owned company based in Verden, Germany. It employs over 600 people and generates a revenue of €60 million. The company develops and manufactures all products in-house, ensuring high quality and compliance with international standards.

LR3 Reactors Brochure-2

BLOCK line reactors can be found throughout the world in many sectors of industry - including mechanical engineering, machine building, electronics, materials handling technology, in servo drives and wherever frequency converters are used. The highly technical and complex automation of industrial systems means that the mains network has to be handled very sensitively. The LR3 line reactor reduces power harmonics and thereby protect your systems against costly downtimes. The well thought-out, completely redesigned structure of the LR3 allows fast and easy installation in even the tightest of spaces....
