With the help of our mechanically
advanced production unit, we are able to manufacture and export a wide assortment of Single
Cum Reverse Phasing Preventor(Auto/ Mannul). The offered phasing
preventor is used for controlling and avoiding the reverse phasing or current
lacking in the circuit. Thee are demanded in agricultural, automobile,
chemical and electrical industry. The provided phasing preventor is properly designed
and assembled in accordance with the industry standards at our well equipped
unit. Further, this Single
Cum Reverse Phasing Preventor(Auto/ Mannul) is available in different specifications at
economical price range.

Features:

Option for auto/manual resetDesigned to operate under all tropical conditions Excellent durability Specifications:Unbalanced supply or Single Phasing results in current increase and double frequency currents in the rotor, which causes over heating and ultimately burn the motor windings.Absence of one phase, while starting the motor causes it to draw a very heavy current, which burn the motor winding in no time.Reverse Phase Sequence results in reverse running of the motor, which endagers the machine connected to it.SINGLE PHASING-CUM-REVERSE PHASING PREVENTOR Provides protection against all the above cases, whether they are caused due to fuse failure, loose connections or loss of phase from the supply itself. The thermal over load relay provided with motor starters does not give protection in any of the above cases. Description It is a small and compact unit based on the latest electronic devices. It monitors the negative sequence voltages in a three phase supply and actuates an electromagnetic relay when it is beyond the set limit. The voltage unbalance and the trip time delay are adjustable from 2 to 10% and 1 to 10 seconds. Input supply and relay ON conditions are indicated by two LED's provided on top of unit.Working Voltage415 VAC, Three Phase 50HzRelay Contact Rating6Amps resistive load at230/440 VAC or 24 VDCInsulation2.5 KV 50 Hz for one minute between all external terminals connected together and body.DimensionsBase------70 x 120 mm, Height---110 mmConnections for D.O.L.
