777-HVR-SP规格书详情
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.
Applications
• Conveyor systems
• HVAC equipment
• Saws and grinders
• Fan motors
FEATURES BENEFITS
Built-in display Visual indication for programming, viewing real-time voltage or
current, and last fault code
Programmable voltage and current settings Allows usage on a wide range of systems
3 selectable restart options Choose from automatic, semi-automatic, or manual to best meet
individual application needs
3 programmable restart delay timers Program separate restart delay time for rapid cycle protection, motor
cool down, and dry-well recovery
Remote display compatibility Increases safety through remote display of real-time data and fault
history. Aids with arc-flash safety regulations
Flexible reset Reset can be done through pushbutton on relay or remotely with
optional 777-MRSW or OL-Reset remote reset kit
