You can replace Integral by Tesys U, although it isn’t a direct replacement and in some applications all the functionalities might not be available. This relates with the vast range of purposed made accessories that the Integral did offer and will not be available in Tesys U, you can still achieve the functionalities but that needs to be checked case by case and using other ranges of products.
This FAQ only focus on the base units and the control units, for more complex arrangement you can contact us (https://www.se.com/uk/en/work/support/customer-care/contact-schneider-electric.jsp) and discuss alternatives:Integral Replaced by Tesys U
Integral 18 and 32 reversing DOL (old model) Tesys U reversing LU2B (new model)The Integral 18 and 32 series starters have been discontinued. They have been replaced by the Tesys U series.
The old Integral and the current range Tesys U serve similar purposes but they are very different devices.
- Integral - was very much "traditional" and conventional technology.
- Tesys U - employs different, more modern and efficient structures and technology, therefore there is no compatibility or interchangeability between any of the parts. This means that to replace any part of the Integral starter will require changing the complete unit for a Tesys U. As there are no directly equivalent
There are 4 levels of control unit (2) with varying levels of functionality, Standard (LUCA) Advanced (LUCB, LUCC and LUCD) and Multifunction (LUCM) and also a Magnetic only version (LUCL).
When replacing Integral it is probably best to go with the Advanced unit (LUCB****) as this gives the optimum level of simplicity and cost combined with flexibility to add additional modules to replicate some of the more complex functions possible with Integral.
