The Model 777 is a fully-programmable electronic overload relay with a LED display Sixteen programmable parameters for extremely flexible use.

• Approvals: UL, cUL, CE, CSA
• Network interface options available.

777 Series Options - Part-Number Suffix.

• -P "Plus" - includes a network programmable HP (high power) setpoint; the TC (trip class) can be set from 2-30 Network requires com module
• -P1 Network alarms - same as -P but includes high and low power alarms that are programmable via the network
• -HVR "High Voltage Relay" Used to eliminate the need of a CPT(Control Power Transformer) on 480V systems. Used in the 380-480V range. Relay rated 480VA @600Vac. Commonly used in pumping applications to save the cost and extra wiring associated with a CPT.
• -MV "Medium Voltage" for use with PT (Potential Transformers) and CT(Current Transformers) 115-240Vac with built in multipliers for CT of 25:5, 50:5, 100:5. Voltage unbalance, single and reverse phase protection can be disabled for use with a single PT.
• -575 480-600Vac range and 240Vac relay. Often used in Canada and NE USA where 575 power is sometimes used.
• -690 600-690Vac range and 240Vac relay. CE listed - but not UL targeted fro central and south America.
• -KW/HP Under load trip based on power. Often used with centrifugal pumps.
• -FT - "Fast Trip" as 500ms - 70s. Often used to prevent damage in overload or jam situations. Sometimes called 'shock relays'.
• -LR - for "Low Range" 1-9A full load motors
• -TS - for Temp Sensor Franklin submersible motors with subtrol.
• -NP "No Parity" on modbus networking
• -SP Sinle Phase 480Vac applications
• -AccuPower for 3-phase pumping applications when the user wants to input the motor’s efficiency and is desired over the utility power. Provides a 4-20mA analog signal proportional to the output power when using a 4-20mA communications module.
