Application
JR28 series thermal overload relay are suitable foroverload and phase-failure protection of AC motors with frequency of 50/60Hzvoltage up to 690V,current up to 0.1-630A under 8-hoursdutyor uninterrupted duty.
Functions provided by these relays,are phase-failure protection,ON/OFF indication,temperature compensation,andmanual/automatic reset.
International Standard:IEC 60947-4-1The relays can bemounted onto contactorsor installed as single units

The main function of the built-in bypass soft starter is to reduce the pressure on the motor during startup by controlling the voltage and current changes, thereby increasing startup efficiency and extending the motor’s lifespan. The built-in bypass soft starter typically includes bypass contactors and control power supplies, enabling a smooth transition to bypass mode during startup to prevent the motor from experiencing excessive current and voltage shocks.

Unique magneic arc extinguishing design with1500V cut-off function Unique contact structurewith higher surge resistance and current tolerance. Environmentally friendly products (RoHS compliant). Load connecton without polarity.
Unique anti short circuit structure,Short circuit resistance:20A~40A:/;60A~100A24000A; 150A-1000A:28000A.
High and low voltage withstand voltageabove 4000V.
The coil connections are all non-polar(60A-100A).The coi can be energy-saving,and the energy-saving coil is connected with polarity(150A-1000A).

General
Grounded socket TMS-5 issuitable for single-phase power supply,used in theauxiliary AC circuit for connecting electrical appliances(portable lamps,powersupply,etc.).
Standard:IEC60884-1.

Introduction
AVR series full-automatic ac voltage regulator is a newly designed products on thebasis ofSVCseries product.With good functions,such as time delay,over voltage,undervoltage etc,the use ofrelay switchoutput transformertap,quick response,andlow energy consumtion can be widely used where need stable woltage likehousehold,hospital,office,industrialautomationandsoon.

Introduction
TSD series servo type hanging automatic ac voltage stabilizer is a newand perfectdesign on the base of the SVC series products.It hasthe excellent function like overvoltage,under voltage protection,main protection and steady voltage shiftautomatically,the hanging type installation can effectively use the space,smoothappearance and color,can give usersaflesh feeling.It can be widely used in mostsituationslike home,hospital,office and where the voltagestability is required.

Introduction
SVC series full-automatical voltage regulator consist of contact autotransformer,servomotor,automatic control circuit etc.When grid voltage or load is changedautomatically sampling control circuit sends a signal to driveservomotor,adjust theposition of the self coupling voltage regulator for carbon brush,make the outputvoltage rating reach the stable state
This product has the waveform distortionless,reliable performance.long-termoperation and other characteristics,such as time delay,over voltage,undervoltageprotection.It can bewidely used in electricitywhich need stablevoltage,it is an idealvoltage stabilized supplytoensurethe normal operationof electricalequipment.

SBW three phases AC voltage stabilizer is a adjustable automatic voltage compensation regulating power device. When voltage from support network is varied due to loading current influence, it automatically regulates the output voltage to ensure the normal function of the electric equipments. Compared with other types of voltage stabilizer, this series product has large capacity, high efficiency, no waveform distortion, stable voltage regulation and other advantages, it supports widely load application, instantaneous overload and continuous long work, manual/auto switch, can also provide over voltage、 lack phase、 phase order and machine faulty automatically protection.
Conveniently assemble and reliable operating (can be digital display/analog display).
