Motor and Pump Protection Relays

77C Series

Single-Phase Current & Voltage Monitor

Description

The single-phase 77C unit is a fully-programmable, electronic overload relay designed to protect any motor drawing 2-800

full load A (external CTs are required above 90 A). Common applications include conveyor systems, HVAC equipment,

saws and grinders, fan motors, and almost any pumping application. The 77C and 777-HVR-SP (family of products) are

for single-phase 100-240 V ac applications.

All of the overload relays provide unsurpassed protection by combining overload, underload, and voltage in one unit.

For standalone applications, the units incorporate a 3-digit LED display that is used for programming, providing real-time

operational information, and displaying diagnostic codes to aid in troubleshooting a fault condition. These units also feature

a communications network port that can be used with communication modules, listed in the 777 accessories section, to

form a Modbus, DeviceNet^™, Profibus, or Ethernet network. Up to 99 units can be remotely monitored and controlled from

a PC, PLC, or SCADA system, and data logging through a PC with the optional Solutions software. This capability allows

for a simple, cost-effective way to meet new requirements for arc-flash safety.
