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.

Versatile handle
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.
