single-phase and 3-phase current & voltage monitor, on-board display, optional
communications to PLC/SCADA/monitoring systems
The Model 777 / 77C
is a fully programmable electronic overload relay
designed to protect any motor drawing 2-800
full load amps (external CTs are required above
90 amps). The 77C (family of products) is for
single-phase 100-240VAC applications and the 777
(family of products) is for 3-phase 200-480VAC
applications, with several specialized units for other
voltage ranges and unique applications. Common
applications include conveyer systems, HVAC
equipment, saws and grinders, fan motors, and
almost any pumping application. Some unique
applications include use with a Subtrol® equipped
Franklin submersible motor to detect high motor
temperatures and applications where a fast linear
trip is required.
All of the overload relays provide unsurpassed
protection by combining overload, underload,
voltage and power monitoring functions in one
package. The overload relays have a 3-digit display
for viewing real-time voltage and current and for
displaying the last or active fault code (to simplify
diagnostics) when tripped for a fault condition.
The units can be used as a stand-alone product
or the communications port can be used to form
a Modbus, DeviceNet™, Profibus, or Ethernet
network to monitor up to 99 units from a PC, PLC,
or SCADA system, and for data logging through a
PC with SymCom’s Solutions software (see page 15).
The communications port can also be used for
remote monitoring (see SymCom’s remote monitors
on page 13) to improve safety for personnel by
allowing them to monitor and control motor
operation without opening the electrical cabinet.
This capability allows for a simple, cost-effective
way to meet new requirements for arc-flash safety.

drawing.

wiring diagrams.

Overload Relay
Model 777 Product Line
single-phase and 3-phase current & voltage monitor, on-board display, optional
communications to PLC/SCADA/monitoring systems
-P2 The 777-P2 protects 200-480VAC, 2-800 full load amp (FLA) motors and provides protection from overvoltage and undervoltage,
overcurrent and undercurrent and unbalanced voltage or unbalanced current through adjustable setpoints. Provides adjustable Trip Class (TC)
settings that include settings from 2-60, with or without “jam” protection, and linear TC from <1 second to 60 seconds. The fast linear TC is ideal
for applications where very short trip delays are needed to prevent chain drives and other drive linkages from breaking in an overload or jam
situation (ex. sewage clarifiers, mixers, augers, conveyors). This family of products also includes network programmable alarm setpoints and
high and low power trip points (programmable through a network or SymCom’s Solutions Software).
-LR (Low Range) The 777-LR-P2 is specifically designed for use with 1-9 FLA motors to ease installation when wired directly, or for 10-800
FLA motors with use of external CTs.
-HVR The 777-HVR-P2 or 777-HVR-LR-P2 is required when a CPT (control power transformer) is not used on a 480V system. They have a
340-480VAC range, a relay rated at 470VA @ 600VAC pilot duty, and is commonly used in pumping applications to save the cost and extra
wiring associated with a CPT.
-HRG The 777-HRG-P2 / 777-LR-HRG-P2 are overload relays, designed for a high resistance ground sytem, that incorporates an internal zerosequence CT (HRG) or an external zero-sequence CT (LR-HRG) to detect ground faults. The HRG is only for 2-90 FLA and is wired directly. The
LR-HRG is only for 10-800 FLA and requires the use of external CTs that correspond with the built-in multipliers.
-MV The 777-MV-P2 is specifically designed for medium voltage applications where both PTs (potential transformers) and
CTs (current transformers) are used. It has a 115-230VAC nominal voltage range and built-in multipliers for 25:5, 50:5, 100:5, …CTs. The voltage
unbalance, single-phase and reverse-phase protection can be disabled to accommodate applications where only one PT is used.
-575 The 777-575-P2 has a nominal 500-600VAC range and 240V relay. They are commonly used in Canada and the Northeast US where 575V
utility power services are common.
-VA-02 The 777VA-02 has RD1 setpoints of 2-500 minutes and UCTD setpoints of 2-60 minutes. (Replaced 777-RD1M-UCTDM).
-VA-03 The 777VA-03 is specifically designed for use with static and rotary single to 3-phase converters. Voltage unbalance protection
is disabled and the high and low voltage trip features apply only to the utility supplied power. This allows the 777 to ignore the severely
unbalanced voltages that are inherent to unloaded phase converters. (Replaced 777-PH.)
-SP The 777-HVR-SP is specifically designed for single-phase, 480VAC applications. It has a high voltage relay rated at 480VA @ 600VAC pilot
duty to handle systems with no control power transformer.
-FT The 777-FT is intended for applications where a fast linear trip is required. It has an overcurrent trip delay that can be set to less than 500ms,
to be used in applications where very short trip delays are needed to prevent chain drives and other drive linkages from breaking in an overload or
jam situation. Often times these are referred to as shock relays. Some applications include sewage clarifiers, mixers, augers and conveyors. The trip
delay can be set to as long as 70 seconds, so the 777-FT can also be used in certain applications when a slower than normal trip is desired, such as
motor test panels in a rewind shop. The 777-FT also features an adjustable motor acceleration time and overcurrent trip delay time when using the
fast linear trip mode.
-TS The 777-TS is specifically designed for use with a Subtrol ®-equipped Franklin submersible motor to detect high motor temperatures.
-DEMO SymCom offers demo packages for the Model 777 family and remote monitors. These demos are powered via one power adapter (included)
and are very easy to set up for use as sales tools or for training purposes. Four packages of the MotorSaver® and four of the PumpSaver® versions
are available ranging from the basic model 777 up to a complete package including the Ethernet module and both remote monitors. Which package
to choose will depend on your markets and/or product focus.)
