Overload Relay

-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

zero-sequence 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.)
