GE Energy Industrial Solutions Spectra RMS Circuit Breakers with microentelliguard Trip Units Greater system coordination, arc flash protection and reliability for new equipment and retrofit applications imagination at work
Spectra RMS Circuit Breakers with microentelliguard Trip Units Enhanced performance for SG600 and SK1200 molded case circuit breakers Spectra SG600 and SK1200 molded case circuit breakers now feature microentelliguard trip units, which bring improved system protection, coordination, selectivity, performance and diagnostics. Advanced interface and capabilities Based on the EntelliGuard TU trip unit platform, microentelliguard delivers the same HMI interface, advanced features and protective functions, including enhanced time-current curve shaping capability, ground fault alarm, direct Modbus communications, reduced energy letthrough setting, zone selective interlock, neutral protection, waveform capture and programmable output contacts. Common accessories and backwards compatibility The microentelliguard trip unit utilizes the same power management accessories offered for the Spectra MicroVersaTrip trip unit, and adds a new advanced junction box, interconnect cable and terminal boards. The footprint and interrupt ratings of the breakers are unchanged, and they are backwards compatible with existing equipment and installations. The microentelliguard trip unit uses the same universal rating plugs and test kit as the EntelliGuard TU trip unit.
microentelliguard Trip Units put you in control of your system You get the flexibility to create the curve shape that best suits your system s need not a one-size-fits-allsolution. Standard Long Time characteristics exactly mimic the curve of a thermal magnetic circuit breaker and closely match our new line of global Record Plus molded case circuit breakers. Optional fuse-like Long Time and Ground Fault curves allow optimum selectivity in systems that employ both fused and circuit breaker devices, providing selectivity and protection simultaneously. MVT I 2 t, thermal CB & fuse I 4 t curves Broad range of adjustments, shapes, slopes, delays You gain the ability to adjust to exactly what your system needs. A wide range of continuous adjustment Long Time delays ensure the circuit breaker can be exactly dialed in to your selectivity and protection needs. You can sustain load and protect optimally all the time. Twelve Short Time bands allow you to set your circuit breaker to sustain load requirements without slowing your protection more than you absolutely must. Flexible curve shaping adapts to every need. Multiple Short Time diagonal bands tune your protection to exactly where it needs to be. You get selectivity and instantaneous clearing at the same time. 1 The Zone Selective Interlocking system simultaneously provides short time, ground fault and instantaneous selectivity. Current metering is standard, and optional power, energy and reactive power metering and waveform capture are available. Flexible serial communications via Modbus RTU makes programming easy for any power or building management system. microentelliguard integrates directly into GE s EnerVista Power Management System. Flexible programmable output contacts are useful for such various needs as load shedding, ground fault alarm, trip indication and many others. A large, easy-to-see, backlit LCD screen makes it easier to set up the trip unit in such environments as a darkened electrical room. Fine adjustment exact delay No more No less ZSI Unrestrained Fuse shaped GF for enhanced selectivity in all systems ZSI Restrained 1 Instantaneous ZSI is available only as an output signal on Spectra microentelliguard trip units Advanced ZSI allows Instantaneous ZSI to withstand ratings
