Quick Links

IMAX SWITCHES is uniquely inbuilt, shrouded, compact with generous terminal capacity and a fused short circuit capacity upto 80 KA.
IMAX SWITCHES are feature rich with asthetic looks, elegance, sturdy & economical. Features that no other SDF offers Because of these unique characteristic the IMAX SWITCHES are in the frontline of protection.

The design of imax switch type FS is based on the innovative : 'QUAD BREAK' principle. This design enables a drastic reduction in the intensity of arc, which is produced at the time of breaking. During breaking the current path is broken at four places in series, thus the arc is reduced. This leads to less strain on the contacts and the life of the switch is increased.
The moving contacts are designed to make two parallel current paths, which produce high electro-magnetic attraction forces during high faults and increase the contact pressure, this eliminates chance of arcing at the contacts and allow the fuse to safely clear the fault. The self-cleaning contacts ensure wiping of deposits during each operation and increase the life of the contacts.

The fuses in imax switches type FS are stationary and are isolated at the both the incoming and outgoing ends, this offers complete safety for fuse replacement in OFF condition.
The switch mechanism is quick-make quick-break i.e. independent of operating speed. Positive ON/OFF indication is provided at the switch handle and mechanism assembly.
The complete range from 32A to 250A is offered in TP/TPN versions. Phase barriers are provided as a standard feature to prevent any accidental fault between the fuses.

Complies with IEC 947-3/IS 13947 part 3

Hitech fuses short circuit capacity : upto 80 KA

No movement of fuses / long life : Stationery fuses with double break arrangement ensure long mechanical & electrical life of switch fuses. The fuse does not run the risk of getting popped out due to shock of movement.

Kompact size / space saving in panels, mcc's & db's. As a result of patented contact construction & the quick make, quick break mechanism, the switch disconnector fuse unit are very compact.

Unique handle with unmatched standard

Provide Ip54 degree of protection.

Adjustable telescopic shaft.

Unbreakable engineering plasting moulded handles.

Provisions for Defeating interlock.

Door interlocking in 'ON' position.

Padlocking facilities both in ON & OFF position.

Range : Switch disconnector fuse units from 32A to 250A

Available in isolable neutral switched neutral design.

The unique contact system and quick Switching mechanism prevents contacts from opening at extreme fault currents.

Fuse links remains isolated from both incoming and outgoing circuits, when the switch is in OFF position.

Available with Knife fuse contacts & also bolted on request.

Available in open execution and with enclosure.

Can be mounted in vertical or horizontal position.

Padlock, door interlock and defeat interlock provided.

Ideally suited for power control centres (PCC).

The Switch disconnector fuses are designed to perform as

Main Switches
Motor circuits switches (AC23 rating upto 660V)
Isolator switches
Local safety switches
Special switches
