Littelfuse SymCom 202-200-SP-NHV MotorSaver Protection Relay.

Littelfuse SymCom 202-200-SP-NHV MotorSaver Protection Relay is a unique microcontroller-based voltage sensing circuit that constantly monitors the single-phase voltage to detect harmful power line conditions. When a harmful condition is detected, the 202-200-SP’s output relay is deactivated after a fixed 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.

Protects 1-Phase Motors From:
• Low voltage

Standard Features:
• Fixed Trip Delay (4 seconds)
• Adjustable Restart Delay (2-300 seconds)
• Constant monitoring of voltage
• Quick mounting: ¼” socket head cap screw (customer supplied)
• Advanced LED indication provides diagnostics for troubleshooting and to determine relay status
• Standard ¼” quick connects
• UL Listed*

*Notes: To obtain UL listing for the 202-200-SP-NHV, use insulated ¼” UL recognized female quick connects; NHV="No High Voltage Shutdown".
