Tsubaki Guide to Forestry Products

SHOCK RELAYSWhen control really mattersAt Tsubaki, our commitment is tobring you the highest value in theindustry today. Period.And as a full line supplier of power transmission products, thiscommitment extends to our complete line of Shock Relay productsas well.Protect your equipment and investment with Tsubaki shock relays andexternal current transformers. Unexpected shock loads can damagechains, drives, gears, turbines – entire mechanical assemblies. Thatmeans high maintenance, costly repairs and expensive downtime.Simply put, when the shock relay detects a problem, it acts like anelectronic shear pin that shuts down the line – quickly, safely andsecurely. That means big savings in both time and money.After the problem is corrected, the shock relay is reset at the touch ofa button. No tear down is required. That means improved effi ciencyand reduced downtime.“SS” Series Shock Relay Plus ExternalCurrent TransformerModel Numbers: TSBSS100, TSBSS200 and TSBSS300The external current transformer is wired together with the“SS” series shock relay to provide overload protection forapplications using large motors – typically over 100A.Start TimeTestConnectionTerminals(contacts)ShockTimeTrip Current“SS” SeriesShock RelayResetExternal CurrentTransformerStandard SpecificationStandard UsageUnit PartsExternal CTPortionTSBSS05 TSBSS30 TSBSS60 TSBSS100 TSBSS200 TSBSS300Load current (current setting range) * 3 0.5~5A 3~30A 5~60A 10~100A 20~200A 30~300AApplicablemotor capacity200V class 0.08hp - 1.5hp 2hp - 7.5hp 10hp - 15hp 20hp - 25hp 30hp - 50hp 60hp - 100hp400V class 0.27hp - 3hp 5hp - 15hp 20hp - 30hp 40hp - 60hp 75hp - 120hp 150hp - 175hp* 4Ambient temperature-20 o C~60 o CAmbient humidity45-85%RH; no condensationOutput Relay * 1Work environment Vibration Less than 5.9m/s 2AltitudeLess than 1000mAmbient atmosphereNo corrosive gas, dustUnit model No. TSBSS05 TSBSS30 TSBSS60 TSBSS05 TSBSS05 TSBSS05Current setting accuracy10% (full scale)Set time rangeStart time * 30.2~30sShock time * 30.2~10sOperation power source (L1-L2)AC90~250V, 50/60HzMaximum motor circuit voltageAC600V, 50/60HzCurrent detection systemTwo-phase CT systemAt the time of tripWhen it trips or the power is shut off, the output relay is not engagedContact capacity1c contact, AC250V 3A (in the case of a resistance load)Self-holding Includes self-holdingNormal stateAt start up there is a 0.5s delay, then the output relay engagesMin. applicable load * 2DC10V, 10mAReset methodPress the RESET button or cut the operation powerOutput relayMechanical100,000,000 timeslife spanElectrical100,000 timesTest functionsinternal circuit and output relay operation checkBetween the circuit & caseAC2000V, 60Hz, 1 minute (power supply circuit and contact circuit)Withstand voltage Between contactsAC1000V, 60Hz, 1 minuteBetween circuitAC2000V, 60Hz, 1 minute (power supply circuit and contact circuit)Gross mass0.2kg (not including external CT)Power consumptionWhen AC110V2.7VA (0.35W)When AC200V11.0VA (1.2W)DIN rail mounting 0 XcUL 0 XCE 0 XExternal CT Model No. Not needed TSB2CT100 TSB2CT200 TSB2CT300Rated primary current - 100A 200A 300ARated secondary current - 5ARated load - 5VAMass - 0.5kgNotes: *1. During normal operation the ouput relay is ON, and when the Shock Relayoperates it is OFF.*2. When directly inputting output relay contact into the programmable controller (PLC),be aware that a minute electric current can cause contact failure.As for the input to PLC, it is recommended to drive the relay coil for minute currentby relay signal of Shock Relay at fi rst, then input this relay contact to PLC.*3. Current and time setting ranges can be set within the warranty range, but notthe upper or lower level of setting volume.*4. When motor size is over 175hp, please contact Tsubaki.Digital DisplayShock Relay & ExternalCurrent TransformerModel Number: TSBED88 89
