We are Manufacturers, Exporters & Leading Suppliers of FT Switch / FT Switches Located in Mumbai, India. The housing is robust, high grade phenolic moulding, capable of long, trouble free performance in varied climatic conditions. It is designed and manufactured for indoor application. The terminals are brass, duly nickel plated. The contacts are spring loaded, silver plated and supported by phosphor bronze strips. Each contact is separated with a SRBP shroud. Screws are provided at the rear for terminations. Alternatively, studs with nuts and washers could also be provided. Sealing holes on cover studs are provided to prevent unauthorized access. The front cover can be removed for test purpose and replaced, thereafter. This cover is fitted with a silver plated contact finger to close the trip contact, when inserted. Otherwise, the trip contact would remain open. Thus the contact finger on the cover, completes the entire circuit. Isolation of the trip circuit is feasible by removing the contact finger fitted to cover thus avoiding unwarranted tripping under test conditions.   FEATURES :  * Facilitates easy in-situ, onload testing of relays, metering and control panels without disrupting load circuit. * Easy and safe for technicians to isolate protection relays, inject test signals and verify system performance. * Rugged Construction* Substantially reduces commissioning and routine maintenance* Compatible with other popular brands of test plugs. INSULATION* Conforms to requirements of IS-3231* Tested for 2.5 KV. IR Valve - 100   MOUNTING* Test block can be projecting or flush mounted     OVERALL DIMENSIONS* Heigh - 100 mm     Width - 180 mm      Depth - 88 mm* Add 25mm for blocks with terminal screws* or add 40 mm for blocks with terminal studs.

Semaphore indicators are designed to perform on Instrumentation. Control &  Relay Panel's mimic diagram. It indicates the 'open' or 'close' position of the circuit Breaker.   PT ON / OFF switch, Earth Switch, Isolator etc. The Dial Needle Positions itself to right angle with reference to the mimic, when the-Isolator, breaker etc .. is in 'Open' position. In "Closed' position of the Isolator. Breaker etc, the needle positions itself to bridge the gap between the lines and provide continuity in the mimic diagram. When supply to the Semaphore Indicator fails. the needle moves to occupy the intermediate position at 45o.   Application : For automatic status indication of Isolators, Earth Switches. Circuit Breakers etc. on Mimic diagram of Control Panels.   Features : Continuously rated heavy duty solenoid coil Dust & vermin proof Exceeds IS-3231 1965 ., specifications Superior operating torque & locking Prolonged test for each unit, for operational accuracy & endurance Aesthetically designed Quality standards matches international standards.

We are offering semaphore indicator. accurate & durable. Tested for 10000 operations before shipment.
