We have been supplying a wide range of L & T Switchgears Products to Various Industries, through our Work, we have built a reputation as a company that combines innovation with integrity with quality range.
Direct On-Line (DOL) method is the simplest starting method for 3-phase pump set. L&T offers two variants of DOL method – starter and controller.
DOL starters are basic electrical starters with contactors and relay for ON/OFF operation and overload protection of the pump set.
Over and above the ON/OFF operation and overload protection features equipped in Controllers, it also provides additional features like Auto ON, indications of Supply ON/OFF and Pump ON/OFF, reading of real time voltage & current of pump with unique Dual analog meter. Single phasing protection relay (SPPR) inside Controller unit provides the advanced protection features viz. single-phasing prevention, phase-reversal protection, phase-unbalance protection, variable time-delay adjustment for delayed operation of pump set
DOL Starters:
- MK1 DOL - with MK1 contactor and MK1 relay
- MU DOL - with MU contactor and MU relay
- MB DOL - with MU contactor and MN relay
- ML DOL - with MU contactor and MN relay
- MU-G6 – with MK1 contactor, MK1 relay and Sz5 (SPPR)
- MU-G10 & MU-G10H - with MU contactor, MU relay and Sz5 (SPPR)
Star Delta Starting is one of the methods of starting of 3-Phase pump-sets. In Fully Automatic version of Star-Delta (FASD) Starter, the changeover from star winding to delta winding is done with the help of a timer. L&T offers two variants of FASD – called starters and controllers.
FASD starters are basic electrical starters with contactor and relay combination for ON-OFF operation and overload protection of the pump-sets. Over and above the ON/OFF operation and overload protection features equipped in Controllers, it also provides additional features like Auto ON, indications of Supply ON/OFF and Pump ON/OFF, reading of real time voltage & current of pump with unique Dual analog meter. Single phasing protection relay (SPPR) inside Controller unit provides the advanced protection features viz. single-phasing prevention, phase-reversal protection, phase-unbalance protection, variable time-delay adjustment for delayed operation of pump set.
FASD Starters:
- MK1 FASD – with MK1 contactors, MK1 relay and GT200 timer
- MU FASD – with MU contactors, MU relay and ST100 timer
- MB FASD – with MU contactors, MN relay and ST100 timer
- ML FASD – with ML contactors, ML relay and ST100 timer
- MU-G15 – with MK1 contactors, MK1 relay and SDz5 (SPPR + timer)
- MU-G20 & MU-G20H – with MU contactors, MU relay and SDz5 (SPPR + timer)
- MU-G30 – ML contactors, MN relay and SDz5 (SPPR + timer)
- MU-G50 - ML contactors, MN relay and SDz5 (SPPR + timer)
- MU-G75 - ML contactors, MN relay and SDz5 (SPPR + timer)
Semi Automatic Star Delta (SASD) is the method of starting 3-phase pump-sets. During the starting of pump-sets, the changeover from star winding to delta winding is done manually. L&T’s SASD starter provides basic function of ON/OFF operation and overload protection of the pump set.
SASD Starter:
- MK1 SASD - with MK1 contactors and MK1 relay
- MU SASD - with MU contactors and MU relay
- MB SASD - with MU contactors and MN relay
- ML SASD - with ML contactors and ML relay
M-POWER – Module for mobile starter is the product for remote operation of the pump set through mobile. The farmer can operate his pump set of the farm through his mobile from anywhere. Farmer just has to give a “Miss Call” to make ON / OFF the pump in his farm.
M-POWER is an auxiliary unit which to be connected along with the starter/controller, so that once connected with starter; a user can control the operation of starter/controller from anywhere anytime.
L&T offers comprehensive solution for single phase submersible pump set and monoblock pump set. There are two version of solution – Starter and Controller. Apart from ON/OFF operations, the starters and controllers provide protection against overload of the pump set.
In addition to this basic function, controller also provides ON/OFF indications, reading of real time voltage & current of pump set through unique Dual analog meter.
Starter:
- MF1 – without no volt coil (only mechanism)
- MU-2P with no volt coil
- MR-G2 – with MU-2P contactor, MK1-2P relay and condensers
- MF-G1 – with MF1 mechanism and condensers
