Littelfuse SymCom 250600 MotorSaver Protection Relay.

Littelfuse SymCom 250600 MotorSaver Protection Relay is a unique microcontroller-based voltage and phase sensing circuit that constantly monitors the three 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 specified amount of time (Restart Delay), unless the unit is in the manual reset mode. The trip and reset delays prevent nuisance tripping due to rapidly fluctuating power line conditions.

The Model 250600 provides high and low voltage protection at fixed percentage of nominal voltage.

Protects 3-Phase Motors From:
• Loss of any phase (single-phasing)
• High and Low voltage
• Voltage unbalance
• Phase reversal

Standard Features:
• Manual - 2-300 seconds variable restart delay
• Advanced LED diagnostics
• Universal range from 475-600VAC 60/50Hz
• Transient protected to meet IC 1000-4-5:1995 Standards and stand up under tougher conditions
• DPDT relay provides two 10A @ 240VAC General Purpose Relays to switch heavier loads
