262 Series Panel Mounted Protector Trip Relays - Crompton ...

262 Series Panel Mounted Protector Trip RelaysA.C. Current Protector Relays262 series A.C. current protector relays provide continuous surveillance. When thecurrent value moves outside the zone limit, the relay operates giving double polechange-over contacts for alarm, control or tripping functions. The unit can be used toprotect against over current or under current conditions for load detection,monitoring of electric heating systems, motors etc. For 3 phase systems, thesequence of connection is not important: simply connect each phase (C.T. secondary)to any pair of terminals marked. An illuminated red LED indicates when the relayis energized.FeaturesAlarm, control or tripping functionsProtection against over or under currentLoad detection and monitoringLED indication of relay and auxiliarypower statusUser accessible reset button optionUser selectable setpoint adjustmentwith optional tamper proof cover5A two pole change over relayBenefits20 second time delay optionLatching option availableEnergize/de-energize function optionsNuisance tripping avoidanceSimple installation and operationApplicationsSwitchgearDistribution systemsGenerator setsControl panelsProcess controlMotor protectionTransformersOverload protectionSpecificationNominal Input Current1A, 5A or 10ASystem Frequency50, 60 or 400HzInput Current Burden0.5VA per phaseOverloads2 x rating continuously, 10 x rating for 3 secondsSet Point Repeatability0.5% of full spanDifferential (Hysteresis)Preset at 1%.

262 Series Panel Mounted Protector Trip RelaysA.C. Voltage Protector RelaysThe 262 series A.C. voltage protectors provide continuous surveillance of themonitored circuit. When the measured voltage moves outside the setpoint limit, therelay will operate giving an alarm or initiation signal. The protector can be used toprotect against under or over voltage, to start up stand-by generators, to operatemains failure units, for switching standby hybrid supplies, protecting computersupplies and similar applications where close regulation is required. The 3 phase, 3or 4 wire models, monitors all of the phases.

262 Series Panel Mounted Protector Trip RelaysFrequency Protector RelaysThe 262 series frequency protector relays will operate giving an alarm, control ortripping signal when the frequency moves outside the setpoint limit. Since the speedof a genset determines the A.C. power frequency this unit can be used to protect A.C.generator plant against overspeed or underspeed. Typical applications include dieselgeneratorsets, standby supplies for industrial, hospital or marine use, mainssupplies, computer supplies and other control gear.
