Protection Relays Voltage Monitoring Relays 460-XXX-SP SERIES Single-phase voltage monitor Description The 460-100-SP is used on 95120 V ac, 50*/60 Hz single-phase motors and the 460-200-SP is used on 190240 V ac, 50*/60 Hz single-phase motors to protect them from damaging high and low voltage conditions. An adjustment knob allows the user to set a 1500 second restart delay. The variable restart delay is also a power-up delay and can be utilized to stagger-start motors on the same system. A unique microcontroller-based, voltage-sensing circuit constantly monitors the voltage to detect harmful power line conditions. When a harmful condition is detected, the MotorSavers output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to an acceptable level and a specified amount of time has elapsed (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions. Features & Benefits FEATURES BENEFITS Proprietary Constant monitoring of voltage to detect harmful microcontroller Wiring Diagram power line conditions, even before a motor starts based circuitry Prevents nuisance tripping due to rapidly fluctuating Fixed trip delay 4 s power line conditions Adjustable restart Allows staggered start up of multiple motors on the same system to prevent a low voltage condition delay (1500s) Provides diagnostics which can be used for Advanced LED indication troubleshooting and to determine relay status DIN rail or surface Allows flexibility for panel assembly mountable Ordering Information MODEL LINE VOTAGE 460-100-SP 95120 V ac 460-200-SP 190240 V ac 2020 Littelfuse, Inc.
