Single Phase Protection Relay Dealers

• Trip Time delay: 2-3 seconds.
• Output contact rating: 5 Amps at 230 V AC.

Protection of induction motors against single phasing or reverse phasing or unbalance supply is one of the major problems in electrical systems. For safe running of 3-phase motors, special protections that keep a continuous watch on supply conditions are very essentials. The major cause of maxium motors burn-out is overloading which occurs due to unbalance supply or single phasing. Phase failure occurs in case of fuse blown-off, loose connections or loss of phase from supply itself.

• Frequency: 50 Hz
• Aux Supply: 415 VAC

Now a days in industries people suffering cause of three phase load problemsburns due to single phasing. SYCON provides Solution On that in form of Single Phase Preventor. General Features Easy installation User Friendly

These relays are useful for protection of 3-phase AC induction motors against various hazards. With their unique advantages they eliminate use of a thermalbimetal relay for motor protection. Being current sensing, they are to be selected according to motor rating and are available for practically all ranges of motors. These relays are ideally suitable for Air-conditioning Compressor motor protection, as also for motors in machines, conveyors, craneshoists and lifts, and for pumps. FEATURES Fixedadjustable unbalance settings Fixedadjustable settings for underover voltage, current, load Fixedadjustable trip delays Resetting Auto or Manual Output contacts : 1 CO or 2 CO Choice of enclosures (DIN-Rail, Flush) Models with Micro-Controller based design Serial Communication (RS485) port 2 line alpha-numeric LCD display Use of SMD Technology User-friendly LED indications

• Features:: Single Phasing Prevention,Reverse Sequence Protection,Unbalance Protection

LECS Auto Switch is designed to monitor the sequence of three phase system. It protects single phasing, reverse sequence and voltage unbalance. It operates in AutoManual mode. It is widely used in agricultural starter panels.

We bring forth vast industrial experience and expertise in this business, involved in offering a high-quality range of Single Phase Protection Relay.

• Supply Voltage: 3 Phase 415 VAC,50 Hz
• ON Delay: 1 to 60 sec.
• Relative HumidityC: 10% to 95%

Protection of 3 Phase devices against Over voltage, Under voltage,Single Phasing, Reverse Phasing & unbalance supply are one of the major issue in electrical systems. For safe running of 3-phase devices, special protections that keep a continuous watch on supply conditions are very essential. The major cause of maximum load burn-out is overloading which occurs due to unbalance supply, Single Phasing & Reverse Phasing conditions. VMR3P detects such Conditions & protect the load from burn out. PROTON's VMR 3P' offer above protections along with 3 digit display showing R-Y,Y-B,BR voltages in scanning mode with precise accuracy. LOWHIGH voltage tripping to ensure trouble free running of 3-phase Loads.

Relay MPR300 is a three-phase LT motor protection relay for motor sizes up to 50KW (max. 88 A current). It is a low cost solution, offering five major protections for motors widely used in fans, pumps, crushers, mills, compressors, belt conveyors, centrifuges, mixers, ventilators, escalators, motorized valves etc. Major advantage is that it provides EF co-ordination in contactor-started motors, thus offering greater security, operator safety and economy. The relay is micro controller based, highly user friendly and compact with inbuilt CTs. The relay can also be used for protection of larger motors by using external CTs. medium voltage and high voltage sub-stations.
