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

Switch-Disconnector-Fuse Range FN & FNX
S-D-F range covers ratings from 32A to 800A. S-D-F’s range is available in both open execution & Sheet steel enclosure version (Suitable for 14x51 Cylindrical, DIN, BS type fuse-link)
S-D-F range provides users with a high level of safety & Convenience. The complete range conforms to IS/ IEC60947-3 standards.
It also carries the CE marking signifying compliance to stringent European safety norms.
S-D-F's superior features translate into better safety & convenience for the users.
Fuse barriers & Terminal shrouds provide protection against accidental direct contact. Terminal shrouds also protect against phase to phase short circuit through an external conducting path.
Double isolation of fuses when S-D-F is in OFF position makes replacement of fuses risk-free.
Positive ON / OFF indication ensures that the handle indicates OFF position only when main contacts are actually open.
Large ground clearance eliminates possibility of phase to ground flash over.
Built-in padlocking arrangement provided to lock the unit in OFF position prevents inadvertent operation of the unit.
The handle coupling has the following user-friendly features:
- Door interlock (defeatable)
- Padlock up to 3 locks
- Choice of operating quadrant
- Flexibility (± 3mm mismatch operational quadrant)
The Switch-Disconnector-Fuse provides complete Flexibility in mounting; Unit can be mounted at any angle in a vertical plane.
Handle depth can be varied and fixed as per requirement during installation. This is possible because the telescopic shaft can be adjusted for stepless variable depth.
