Littelfuse SymCom 460-14 MotorSaver Protection Relay.

Littelfuse SymCom 460-14 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

The Model 460-14 automatically sense whether they are 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. It is equipped with 2 sets of contacts: Form A (NO) and Form B (NC) (used for applications requiring 2 different voltages such as 5VDC for a PLC input and 115VAC for an alarm). Other adjustments include a 1-30 second trip delay, a 1-500 second restart delay, and a 2-8% voltage unbalance trip point adjustment.

• Isolated output contacts: 1 NO and 1 NC
