Littelfuse SymCom 460 MotorSaver Protection Relay.

LittelfuseSymCom 460 MotorSaver is designed to protect 3-phase loads from damaging power conditions. The 460's wide operating range of voltages, combined with UL and CE compliance, makes this a perfect choice for your motor's protection. This is a must have device for applications where power supply quality is uncertain. This premium quality and cost-effective protection device is an alternative from high replacement costs of your electric motor.

MotorSavers unique microcontroller-based voltage and phase-sensing circuit constantly monitors the 3-phase voltages to detect harmful power line conditions. When a harmful condition is detected, the MotorSaver's output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to an acceptable level for a specified amount of time (restart delay). The trip delay prevents nuisance tripping due to rapidly fluctuating power line conditions.

Protects 3-Phase Motors From:
• Loss of any phase
• Low voltage
• High voltage
• Voltage unbalance
• Rapid Cycling

460 MotorSaver automatically senses whether it is connected to a 190-240V, 60Hz system, a 440-480V, 60Hz system, or a 380-416V, 50Hz system. An adjustment is provided to set the nominal line voltage from 190-240 or 380-480VAC. Other adjustments include a 1-30 second trip delay, 1-500 second restart delay, and 2-8% voltage unbalance trip point.

• The 460’s universal range from 190-480VAC, 50/60 Hz provides the versatility needed to handle global applications.
• Dagnostic LEDs indicate trip status and provide simple troubleshooting.
• Microcontroller-based circuitry provides better accuracy and higher reliability than analog designs.
• Transient protection meets IEEE and IEC standards to allow operation under tough conditions.
• One 10 Amp general purpose Form C relay
