You can replace Integral with TeSys Ultra, although it is not a direct replacement and in some applications all the functionalities might not be available. This relates to the vast range of purpose-made accessories that the Integral offered but are not available in TeSys Ultra. You can still achieve the functionalities but that needs to be checked case by case and using other ranges of products and / or combinations of accessories

Integral Replaced by TeSys Ultra
Integral 18 and Integral 32 DOL (old model) TeSys Ultra - LUB (new model)
The Integral 18 and 32 series starters have been discontinued. They have been replaced by the TeSys Ultra series.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 parts.
To replace the simple motor starter aspect is easy. A basic TeSys Ultra Motor Starter comprises only 2 parts, the base unit (1) which contains the contactor (non-reversing) , rated at up to 12A, 32A (LUB12 or LUB32 respectively) and a Control unit (2), which determines both the control voltage and the overload current range.
There are 3 levels of control unit (2) with varying levels of functionality, Standard (LUCA) Advanced (LUCB, LUCC and LUCD) and 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.
