Switch-Disconnector-Fuse Switch-Disconnector Type FN

1 Switch-Disconnector -Fuse switch -DisconnectorType FN Features of FN series : Compact design saves space Electrodynamic Compensation Quad break Contact System Full AC - 23 A rating for the Complete range Highest fused Short Circuit Capacity Quick make / Quickbreak / Positive break Clear ON / OFF indicator Separate arcing / Current carrying zone High clearance & Creepages Separate bridge for each pole Maximum ground Clearance Phase barrier & Terminal Shroud as a Standard accessory Fuse stationary & Isolated from both sides Direct access to mounting & terminal screws Generous terminal

2 Capacity Replaceable contacts for enhanced life Suitable for vertical & horizontal orientation Wide range of Spares & Accessories Handle coupling as per IS 8623 The handle coupling has the following user-friendly fixing of handle on panel door by two interlockfor safety of operating personnel when switch is ON . The interlock can be defeated if required. Built-in padlocking arrangement to lock the unit in either ON or OFF handle coupling can take a mismatch or 3mm in all making & breaking capacity Due to Quad break Electrical & Mechanical ON / OFF indication is provided on the switch (by a red pointer)Built-in neutral : Switch-Disconnector -Fuse consist of an integral neutral, making the units suitable for 3 phase, 4 - wire application.

3 FN 32 / 63 has switched neutral while higher ratings have isolable : This mechanism is front operated quick-make / quick-break and independent of speed of FEATURES1 Compact construction : To ensure light weight low operating torque switch which saves panel to maintain barriers :Interphase barriers are provided to eliminate the possibility of interphase short Switch-Disconnector -Fuse units can be mounted at any angle in a vertical are isolated from both sides. This offers safety to operating personnel while replacing remain stationery during switching Ground Clearance to eliminate possibility of phase-ground flash terminals to accommodate Aluminium bus bars.

4 The terminals can be shrouded for protection against phase-phase short circuit through an external conducting path and also for protection against accidental human contact to live shrouds, to protect against phase-phase short circuit Contact System : Contact system is QUAD BREAK. There are no. of parallel moving contacts per pole per break. Hence,better Arc Quenching & more electrical life of contacts. Each pole has separate bridge, carrying the moving contacts, achieving a high order of interphase separation & avoiding phase-phase flash Interior in Sheet Steel Enclosure : Complete range of S-D-F is also available in attractive powder coated sheet steel 32 / 63 in sheet steel enclosure comes fitted with gland of poles in series, utilization categoryat rated current3, DC-23 A3, DC-23 A2, DC-23 A2, DC-23 A2, DC-23 A2, DC-23 A2, DC-23 A2, DC-22 A2, DC-22 A2, DC-22 A2, DC-22 B32 TECHNICAL DATANo.
