      What is the difference between an LUB12 32 & LUB120 320 Tesys U starter?

      What is the difference between an LUB12 32 & LUB120 320 Tesys U starter?
      The Tesys U non reversing starter controller offers two types of power base units in its range
      LUB12 & LUB120 (0 – 12A, 5.5kw at 400V)
      LUB32 & LUB320 (0 – 32A, 15kW at 400V)
      LUB12 & LUB32 power bases have gone through an evolutionary change.
      Pre 2010 wk36, the base unit was coloured black\white & the contact block LU9BN11 was removable.
      Post 2010 wk 36, the base unit is black, to denote power & the contact block LU9BN11 is now fixed.
      LUB210 & LUB320 will always be delivered with all slots empty (removable plastic covers) which will enable the customer to select their own contact \communication arrangements. Therefore, part No.: LU9BN11 is compatible
      The LUB120 & 320 have also gone through the same colour change as previously mentioned
      Part No.: LU9BN11:
      Is a contact block comprising of, 1NO (13-14) & 1NC (21-22), which indicate the state of the main poles
      Although, some customers are familiar with the model U bases with plug in units. It is worth a reminder that, the new pre wired contacts in the LUB12 & 32 arefixed & are not meant for removal.
      If they are removed (with some effort) it will render the base unit inoperable & a new one will have to be purchased.

      The LUB32 can be used in CAT 3 Safety applications as the contacts are mirrored and linked.

      What would be a replacement mech for a WHT35 ?

      The WHT35 has been replaced with the WHB340-RG however we don't do spare mechanisms for it.

      Surface Switches - Weather Protected, Surface Switches - WHB Series - Weathershield - IP66, Switch 440V 40A - triple pole.

      The WHA/WHB/WHC series of weatherprotected isolating switches is a robust range of switches suitable for virtually any external application. The impact resistant base and cover will survive the hardest knocks in almost any installation. The two sections are sealed with a co-injection gasket. The range provides ample conduit entries and is suitable for side entry from a vertical duct. Its compact size means it is aesthetically pleasing and suits installations where space is limited such as with residential air conditioning applications.

      Please see following link under the documentations tab for complete whb range and technical data.

      What, if any, are the mounting restrictions for the U-Line starter operating positions ?

      The devices are limited to a tilt (front to back ) of no more than 30 degrees from vertical and a sway (sideways) of no more than 90 degrees to the left or the right.
